Embodiment 1.
FIG. 1 is a configuration diagram showing the configuration of a monitoring and control device 11 provided in a combined heat and power generation system 100 according to the first embodiment. The combined heat and power system 100 is installed, for example, at the facility 5A. A monitoring control device 11 is installed within the facility 5A. The facility 5A is a building, a factory, or the like. Furthermore, electric load equipment 1, heat load equipment 2, power supply equipment 3, and heat source equipment 4 are installed in facility 5A. Further, an entrance/exit control system 18 is installed at the entrance/exit of the facility 5A. Further, the facility manager or facility user of the facility 5A carries a smartphone 17. The smartphone 17 transmits input data 9 to the monitoring control device 11 when data is input by a facility manager or a facility user.

The monitoring and control device 11, the electric load equipment 1, the heat load equipment 2, the power supply equipment 3, the heat source equipment 4, and the room entry/exit management system 18 are connected via a communication path so that they can communicate with the smartphone 17. The communication path consists of only wireless communication or a combination of wired and wireless communication. Further, the supervisory control device 11 is connected to the Internet 20 via a communication device 16.

Additionally, a plurality of sensors 10 are installed within the facility 5A. The sensor 10 measures various data and transmits the measured data 7 to the monitoring control device 11 . The sensor 10 may be built into equipment within the facility 5A, added to the equipment later, or installed independently. Here, the equipment includes, for example, the electric load equipment 1, the heat load equipment 2, the power supply equipment 3, the heat source equipment 4, and the room entry/exit management system 18. In addition, the equipment is a switchboard or power receiving equipment that supplies power to each equipment such as the electric load equipment 1, the heat load equipment 2, the power supply equipment 3, the heat source equipment 4, and the access control system 18, or the facility manager or There are smartphones 17 owned by facility users. Among the sensors 10, examples of the sensors 10 that are installed independently include, for example, a thermometer that measures indoor or outdoor temperature, or a hygrometer that measures indoor or outdoor humidity.

The monitoring control device 11 includes a storage unit 12 and an operation planning device 13. The storage unit 12 stores registered data 6 including architectural design data for the facility 5A and equipment design data for each of the electrical load equipment 1, heat load equipment 2, power supply equipment 3, and heat source equipment 4. I remember it in advance. The registration data 6 includes, for example, the total floor area of the facility 5A, the purpose of use of the facility 5A, and the equipment specifications of each of the equipment 1 to 4 of the electrical load equipment 1, the heat load equipment 2, the power supply equipment 3, and the heat source equipment 4. Contains data such as. The operation planning device 13 utilizes the registered data 6 stored in the storage unit 12 and the measurement data 7 that can be collected from the sensor 10 to create an operation plan for the power supply equipment 3 and the heat source equipment 4, and to provide information to the facility manager. Proposals will be made on how to operate Facility 5A, etc.

The supervisory control device 11 holds the registration data 6 held by the supervisory control device 11 in the storage unit 12 in advance. Therefore, the supervisory control device 11 refers to the design information of the facility 5A and each of the facilities 1 to 4, such as the total floor area and intended use of the facility 5A, and the equipment configuration of each of the facilities 1 to 4, based on the registered data 6. can.

Additionally, the monitoring and control device 11 can acquire measurement data 7 from each sensor 10. Furthermore, the supervisory control device 11 can acquire external data 8 obtained through communication with the outside via the Internet 20. External data 8 is data obtained from content 21 on the Internet 20. As shown in Figure 1, examples of the content 21 include weather information, weather forecasts, infrastructure recovery information, other monitoring and control equipment 11X installed in remote locations, disaster information, disaster response status, social network service information, etc. can be mentioned. In this way, the external data 8 includes, for example, information regarding weather and information regarding disasters.

Additionally, the supervisory control device 11 can obtain input data 9 that a facility manager or a facility user inputs to the supervisory control device 11 via an interface (not shown) included in the supervisory control device 11. . Examples of interfaces included in the supervisory control device 11 include a keyboard, a mouse, and a display connected to a computer that executes each function of the supervisory control device 11. Furthermore, other examples of interfaces provided by the supervisory control device 11 include a computer, a smartphone 17, and the like that can access the functions of the web server provided by the supervisory control device 11.

These data 6 to 9 are used by the supervisory control device 11 to determine how to operate the facility 5A in the event of a disaster. However, all of these data 6 to 9 are not necessarily necessary, as it is enough to have enough data to determine the operation method. That is, the supervisory control device 11 uses at least one of these data 6 to 9 as necessary. For example, a case will be described in which data on the number of evacuees at the time of a disaster is required in order to determine the operating method of the facility, such as how to accommodate evacuees in each space of the facility 5A at the time of a disaster. In this case, for example, there are the following three cases.
(1) A predetermined expected number of people is stored in the registration data 6 held by the monitoring and control device 11, and the number of people in the registration data 6 is used as the number of evacuees.
(2) The sensor 10 attached to the entry/exit management system 18 measures the number of people staying in the facility 5A, and the measurement data 7 obtained by the measurement is used as the number of evacuees.
(3) The facility manager of the facility 5A inputs the number of people confirmed at the site using the smartphone 17. Then, the input data 9 may be transmitted to the monitoring control device 11 and used as the number of evacuees.
In this way, the monitoring and control device 11 may use, for example, any one of the registration data 6, the measurement data 7, and the input data 9 in order to determine the operation method of the facility.

FIG. 2 is a diagram showing the connection relationship among the electric load equipment 1, the heat load equipment 2, the power supply equipment 3, and the heat source equipment 4 in the combined heat and power supply system 100 according to the first embodiment. The power supply equipment 3 is connected to the electric load equipment 1 and the heat source equipment 4. Further, the heat source equipment 4 is connected to the heat load equipment 2.

The power supply equipment 3 consumes fuel to generate electricity. Fuel is supplied to the power supply equipment 3 from outside the facility 5A during normal times, but when supply from the outside cannot be received during a disaster, fuel stored in advance in the facility 5A is consumed. Examples of the power supply equipment 3 include a micro gas turbine generator, a diesel generator, and the like. The electricity generated by the power supply equipment 3 is mainly supplied to the electrical load equipment 1 which consumes electricity for operation. The main energy consumption of the electric load equipment 1 is electricity. However, here, the electric load equipment 1 also includes equipment that operates by receiving supplementary heat supply. Examples of equipment classified as electrical load equipment 1 include electric lights 1a, individual distributed air conditioners 1b, and the like. The electric light 1a is installed in a space to be illuminated, and generates light that illuminates the space. The individual distributed air conditioner 1b is installed in a space to be air-conditioned, and supplies heat (cold heat or hot heat) to the air in the space. The individual distributed air conditioner 1b has a heat exchanger, and performs heat exchange between the refrigerant flowing inside the heat exchanger and the air flowing around the heat exchanger. Further, the electricity generated by the power source equipment 3 can also be supplied to the heat source equipment 4. Furthermore, exhaust heat that is generated as a secondary product when the power supply equipment 3 generates electricity can be supplied to the heat source equipment 4 and used effectively.

The heat source equipment 4 receives electricity, fuel, or both electricity and fuel and generates heat (cold heat, hot heat, steam). Electricity and fuel are supplied to the heat source equipment 4 from outside the facility 5A during normal times, but if supply from the outside cannot be received in the event of a disaster, fuel stored in advance in the facility 5A may be consumed, or , is supplied and operated from the power supply equipment 3. Examples of the heat source equipment 4 include heat source equipment such as a chiller and a boiler. Other examples of the heat source equipment 4 include an exhaust heat recovery heat exchanger, an exhaust heat injection type absorption refrigerator, etc., which are operated using the exhaust heat received from the power supply equipment 3. The heat generated by the heat source equipment 4 is mainly supplied to the heat load equipment 2 that consumes heat. The main energy consumption of the heat load equipment 2 is heat. However, here, the heat load equipment 2 also includes equipment that is operated by receiving an auxiliary supply of electricity. Examples of equipment classified as heat load equipment 2 include a central heat source type air conditioner 2a, a water heater 2b, and the like. The central heat source air conditioner 2a cools or heats the room by supplying cold or hot heat to the indoor air. The central heat source type air conditioner 2a sends cold water or hot water to a heat exchanger, and in the heat exchanger, heat exchange is performed between indoor air and cold water or between indoor air and hot water. The water heater 2b supplies hot water to the hot water tank by supplying warm water to water.

FIG. 3 is a diagram showing the connection relationship among the power source/heat source equipment 30, the electric load equipment 1, the heat load equipment 2, and the heat source equipment 4 in the combined heat and power supply system 100 according to the first embodiment. In FIG. 3, a facility 5A is provided with a power source/heat source facility 30 configured such that the power source facility 3 and heat source facility 4 shown in FIG. 2 function as one. The power source/heat source equipment 30 receives fuel supply and generates electricity and heat. Examples of the power source/heat source equipment 30 include a gas cogeneration system, a fuel cell, and the like. In the example of FIG. 3, a heat source facility 4A is installed alongside the power source/heat source facility 30. Here, in order to distinguish the heat source equipment 4A from the heat source equipment 4 that constitutes the power supply/heat source equipment 30, the letter "A" is added to the end of the code, but the configuration and operation of the heat source equipment 4A are It is basically the same as equipment 4. As explained using FIG. 2, the heat source equipment 4 and 4A receive electricity, fuel, or both electricity and fuel to generate heat (cold heat, hot heat, steam). Note that in FIG. 3 as well, as in FIG. 2, the electricity and waste heat generated by the power source/heat source equipment 30 are utilized by the heat source equipment 4A. Further, the electricity generated mainly by the power source equipment 3 of the power source/heat source equipment 30 is consumed by the electric load equipment 1, and the heat generated mainly by the heat source equipment 4 of the power source/heat source equipment 30 is consumed by the heat load equipment 2. . Further, the heat generated by the heat source equipment 4A is consumed by the heat load equipment 2. In this way, the operations of the power source equipment 3 and the heat source equipment 4 included in the power source and heat source equipment 30, and the attached heat source equipment 4A are the same as those of the power source equipment 3 and the heat source equipment 4 shown in FIG.

The power supply equipment 3 and the heat source equipment 4 can be installed either by combining the power supply equipment 3 and the heat source equipment 4 and installing them individually as in the example of FIG. The heat source equipment 4 and the heat source equipment 4 may be operated as an integrated unit. However, in either case, the system as a whole is configured to be able to meet the demands of both the electric load equipment 1 and the heat load equipment 2, and the exhaust heat generated in the power supply equipment 3 is used in the heat source equipment 4. shall be. Such a system is called a "combined heat and power system 100."

The combined heat and power generation system 100 generates electricity and heat, but the efficiency of the combined heat and power generation system 100 changes depending on the ratio of the amount of energy between electricity and heat. When the power supply equipment 3 generates electricity, exhaust heat is generated from the power supply equipment 3 at the same time as electricity. When the power supply equipment 3 generates electricity according to the usage amount of the electric load equipment 1, the amount of exhaust heat is determined according to the characteristics of the power supply equipment 3. The waste heat is converted by the heat source equipment 4 so that it can be used by the heat load equipment 2. Exhaust heat in an amount greater than the amount consumed by the heat load equipment 2 is no longer needed and is therefore not effectively utilized and is discarded. Here, "throw away" refers to natural heat radiation or heat radiation via a cooling tower. For this reason, of the energy of the fuel input into the power supply equipment 3, the amount of waste heat that is wasted becomes energy that is not effectively utilized, and thus the energy efficiency of the entire system decreases.

The ratio of the electricity generated by the combined heat and power system 100 to the heat generated accordingly is called the thermoelectric ratio. Here, "heat" includes both the exhaust heat generated by the power source equipment 3 and the heat generated by the heat source equipment 4. The thermoelectric ratio of the combined heat and power generation system 100 is determined based on the characteristics of the combined heat and power generation system 100. The thermoelectric ratio may only take a fixed value depending on the combined heat and power generation system 100, or the thermoelectric ratio may be variable within a certain range. However, because it is impossible to convert all the energy of the fuel input into the power supply equipment 3 into electricity due to the principle of the generator that constitutes the power supply equipment 3, the thermoelectric ratio does not take any value.

The closer the ratio of electricity and heat used by the electric load equipment 1 and the heat load equipment 2 to the thermoelectric ratio of the combined heat and power generation system 100, the more efficiently the combined heat and power generation system 100 can use energy. Generally, facilities such as office buildings use a large amount of electrical load equipment 1 and a small amount of heat usage from thermal load equipment 2, so the thermoelectric ratio may not match with the existing combined heat and power system 100. On the other hand, in facilities that use a large amount of heat, such as hospitals and hotels, the thermoelectric ratio is often close to that of the existing combined heat and power system 100, and efficient energy use can be achieved. In this way, the combined heat and power system 100 calculates the efficiency, that is, the amount of energy effectively used out of the input energy, based on the amount of heat and electricity used in the electric load equipment 1 and the heat load equipment 2 on the energy use side. The proportion changes.

Next, energy usage in the facility 5A in the event of a disaster will be explained. In the event of a disaster, the actual state of energy usage in the facility 5A changes depending on the level of the disaster, but here, we will consider a case where electricity and fuel cannot be procured from outside the facility 5A, or a case where there is a limit to the amount procured. "Limited" means that there is a power outage but it is possible to discharge from the storage battery, that new fuel cannot be procured but there is fuel stockpiled, or that there is a rotating power outage and there is a period of power outage. There may be times when it can be used, etc.

In the event of a disaster, the facility 5A is given a guideline for continued independent operation or an "energy sustainment target time" according to the needs of the time or region.

Depending on the scale of the disaster, rescuing survivors is prioritized for 72 hours after a disaster occurs. For this reason, it is said that relief supplies and aid for evacuees will not begin in earnest until 72 hours after the disaster occurs. Furthermore, since it takes a considerable amount of time to restore energy infrastructure such as electricity and gas, it is desirable for facility 5A to be energy independent for at least 72 hours, and ideally for about a week. In this way, the "energy continuation target time" is a target period during which the facility 5A continues to operate in an energy-dependent manner without receiving support supplies or aid. Note that the above-mentioned values such as 72 hours and 1 week are merely examples and are not limited thereto.

If energy procurement is restricted and the facility 5A is to be operated in an energy-independent manner for the duration of the "target energy duration time", it may be necessary to limit energy use. For example, when running a generator by consuming fuel to meet electricity demand, if the future demand for electricity is known, the generator can be operated based on the remaining amount of fuel and the characteristics of the generator. Predictable uptime. In addition, if the predicted operating time is less than the "Energy Sustainability Target Time", we will give up on meeting some of the electricity demands and respond to the demand depending on the importance or urgency, or according to human judgment. , supplying electricity only to selected demands.

As mentioned above, the electric load equipment 1 and the heat load equipment 2 are present in the facility 5A. As described above, in the combined heat and power generation system 100, the efficiency changes depending on the thermoelectric ratio. When energy procurement is restricted, by changing the ratio between the amount of electricity used by the electric load equipment 1 and the amount of heat used by the heat load equipment 2 of the facility 5A, and the total amount of electricity and heat used, Allows self-sustaining operation to continue for a preset "energy duration target time".

FIG. 4 is a diagram illustrating an example of reducing the amount of energy used and extending the target energy duration time by changing the thermoelectric ratio in the combined heat and power system 100 according to the first embodiment. FIG. 4(a) shows a graph before the thermoelectric ratio is improved, and FIG. 4(b) shows a graph after the thermoelectric ratio is improved. FIGS. 4(a) and 4(b) each show two bar graphs, a bar graph representing the demand amount and a bar graph representing the supply amount. Further, in the following description, the configuration of FIG. 3 in which the power source/heat source equipment 30 is provided is cited as an example.

As shown in the graph on the left side of FIG. 4(a), before the improvement, there is a demand D1 for electricity and a demand D2 for cold water as heat. The demand for electricity D1 is greater than the demand for cold water D2. At this time, as shown in the graph on the right side of FIG. 4A, the electricity demand D1 is satisfied by the electricity supply G1 generated by the power source/heat source equipment 30. The demand D2 for cold water is satisfied by converting the waste heat G2 generated from the power source/heat source equipment 30 into cold water via the heat source equipment 4, which is the exhaust heat input type absorption refrigerator. Among the exhaust heat of the power source/heat source equipment 30, there is exhaust heat G3 that is not used for generating cold water, and this exhaust heat G3 is discarded without being used.

Therefore, it is desirable to reduce the electricity demand D1 and increase the cold water demand D2 so that the waste heat G3 is reduced. Therefore, in order to realize such improvements, the operating methods of each of the facilities 1 to 4 will be changed.

Specifically, for the individual distributed air conditioners that constitute the electrical load equipment 1, in order to reduce the electricity demand D1, an area is created where they are not subject to operation, and the operation of the individual distributed air conditioners is stopped in that area. do. On the other hand, regarding the central heat source type air conditioner 2a that constitutes the heat load equipment 2, the operation of the area will be increased. In this way, the operating method of the electrical load equipment 1 and the thermal load equipment 2 is changed. This change can be realized by changing the operating method of the facility 5A, such as simply stopping the individual distributed air conditioners or changing the evacuation area for evacuees to the central heat source air conditioner area. By changing the evacuation site for evacuees to an area that is air-conditioned by central heat source air conditioners, there is no need to operate individual distributed air conditioners, and the amount of operation of central heat source air conditioners can be increased. In order to create such a situation within the facility 5A, the operating method of the electrical load equipment 1 and the thermal load equipment 2 is changed by changing the operating method of the facility 5A.

As shown in the graph on the left side of FIG. 4(b), after the improvement, compared to before the improvement, the demand for electricity D1 has decreased and the demand for cold water D2 has increased. As shown in the graph on the right side of FIG. 4(b), the electricity demand D1 is satisfied by the electricity supply G1 generated by the power source/heat source equipment 30. The demand D2 for cold water is satisfied by converting the waste heat G2 generated from the power source/heat source equipment 30 into cold water via the heat source equipment 4, which is the exhaust heat input type absorption refrigerator. Among the exhaust heat from the power supply and heat source equipment 30, there is exhaust heat G3 that was not used to generate cold water, but the exhaust heat G3 has decreased compared to before the improvement.

In this way, after the improvement, the electricity consumed by the individual distributed air conditioner 1b is reduced, so the electricity demand D1 is reduced. The amount of power generated by the power source/heat source equipment 30 can be reduced by this amount. In other words, the amount of fuel consumed by the power source/heat source equipment 30 is reduced.

If the individual distributed air conditioner 1b is simply stopped, the demand for cold water D2 remains unchanged. When the evacuation site for evacuees is changed and the operation amount of the central heat source air conditioner 2a is increased, the demand for cold water D2 increases. In either case, the demand for electricity D1 decreases and the demand for cold water D2 remains unchanged or increases, so the ratio of heat to electricity consumption increases.

As the demand for cold water D2 increases, the amount of cold water generated by the power source and heat source equipment 30 from waste heat increases, so the amount of waste heat G2 used increases. As the amount of power generation decreases, the amount of exhaust heat also decreases, but if the sum of the absolute value of the decrease in the amount of exhaust heat and the increase in the amount of waste heat usage is less than the exhaust heat G3 before improvement, the chilled water demand D2 can be fully satisfied.

If the demand for cold water D2 increases by changing the evacuation site for evacuees and increasing the operation amount of the central heat source air conditioner 2a, the demand for cold water D2 will increase after satisfying the required demands D1 and D2. The fuel consumed by the heat source equipment 30 can be reduced. Furthermore, by combining the simple method of reducing electricity demand by stopping individual distributed air conditioners with the method of changing evacuation areas, fuel consumption can be further reduced.

As described above, by changing the control of each facility 1 to 4 or changing the operation method of facility 5A so as to change the thermoelectric ratio of demands D1 and D2, energy consumption can be reduced and the facility It is possible to extend the "target energy duration time" during which 5A continues autonomous operation.

The control of the equipment 1 to 4 is not limited to reducing the electricity demand D1, but may also consider increasing the electricity demand D1.

FIG. 5 shows that in the combined heat and power system 100 according to the first embodiment, the energy consumption is reduced by increasing the demand for electricity D1, decreasing the demand for heat from hot water, and changing the thermoelectric ratio. It is a figure which shows the example which extends time. FIG. 5(a) shows a graph before the thermoelectric ratio is improved, and FIG. 5(b) shows a graph after the thermoelectric ratio is improved. FIGS. 5(a) and 5(b) each show two bar graphs, a bar graph representing the demand amount and a bar graph representing the supply amount.

As shown in the graph on the left side of FIG. 5(a), before the improvement, there is a demand D1 for electricity and a demand D2 for hot water as heat. The demand for electricity D1 is smaller than the demand for hot water D2. At this time, the electricity demand D1 is satisfied by the electricity supply G1 generated by the power source/heat source equipment 30. The demand for hot water D2 is achieved by converting the exhaust heat from the power source and heat source equipment 30 into hot water via a heat exchanger, but this alone is insufficient. For this reason, the boiler constituting the heat source equipment 4 generates hot water BO to compensate for the shortage.

As shown in the graph on the left side of FIG. 5(b), after the improvement, compared to before the improvement, the demand for electricity D1 increases and the demand for hot water D2 decreases.

In this way, after the improvement, the control of each of the facilities 1 to 4 or the operating method of the facility 5A is changed so that the electricity demand D1 increases, so the power generation amount of the power source/heat source facility 30 increases. are doing. Therefore, the amount of fuel consumed by the power source/heat source equipment 30 increases. On the other hand, since the amount of exhaust heat generated by the power source/heat source equipment 30 also increases, the amount of hot water generated from the exhaust heat also increases. Since the shortage in the amount of hot water supplied to the demand D2 is reduced, the operation of the boiler that constitutes the heat source equipment 4 is reduced. Therefore, the amount of fuel consumed by the boiler constituting the heat source equipment 4 is reduced. The fuel consumption can be reduced by the amount by which the increase in the fuel consumption of the power source/heat source equipment 30 is less than the decrease in the fuel consumption of the boiler constituting the heat source equipment 4.

FIG. 18 is a plan view showing an example of the configuration of a facility 5A in which the operation planning device 13 according to the first embodiment is installed. As shown in FIG. 18, the facility 5A has a plurality of areas R1 to R5. The areas R1 to R5 are, for example, living spaces in the facility 5A, and are partitioned from each other by walls or the like. Electric lights 1a constituting electrical load equipment 1 are provided in each area R1 to R5. Furthermore, a central heat source type air conditioner 2a that constitutes the heat load equipment 2 is provided in the area R1. On the other hand, individual distributed air conditioners 1b constituting the electric load equipment 1 are provided in areas R2 to R5.

Therefore, if the operation method of the facility 5A is determined so that all evacuees stay in area R1, the demand for hot water or cold water D2 increases, and the demand for electricity D1 can decrease. Furthermore, if the operating method of the facility 5A is determined so that all the evacuees are divided into areas R2 to R5 and stay there, the demand for hot water or cold water D2 can be reduced, but the demand for electricity D1 will increase. Furthermore, if the operation method of the facility 5A is determined so that all evacuees stay in one of areas R2 to R5, the demand for hot water or cold water D2 can be reduced, and the demand for electricity D1 can also be reduced. be able to. However, in this case, the evacuees will be crowded in the area, so there is a possibility that the evacuees will feel uncomfortable. In this way, by determining the operating method for the facility 5A, the operating method for the electrical load equipment 1 and the thermal load equipment 2 is also determined. Furthermore, since the electric load and the heat load are determined thereby, an operation plan for the power supply equipment 3 and the heat source equipment 4 can be generated accordingly.

Further, the input data 9 may include data as a result of judgment by a facility manager or a user.

The measurement data 7 is data measured by each sensor 10. The measurement data 7 includes physical quantities including, for example, the temperature, humidity, illuminance, flow rate, and pressure at the location where the sensor 10 is installed in the facility 5A, as well as the electric power and electric energy in the power supply equipment 3 or the electrical load equipment 1.

Furthermore, the measurement data 7 includes the start/stop, operation mode, and abnormality of each equipment for each equipment 1 to 4 installed in the facility 5A, such as electrical load equipment 1, heat load equipment 2, power supply equipment 3, and heat source equipment 4. , etc., may also include data on the operational status of the equipment. Furthermore, the measurement data 7 may include data on the flow of people, including the number of people entering and exiting the facility 5A, each room in the facility 5A, or the region 50 (see FIG. 8), or personal data. good.

This information includes at least one of the information transmitted and received from the remote monitoring and control device 11X.

The remaining energy amount obtaining unit 102 obtains the remaining amount of energy that can be used until the "energy duration target time" representing the time during which the power supply equipment 3 and heat source equipment 4 are desired to continue operating has elapsed. The remaining energy amount acquisition unit 102 calculates the remaining amount of usable energy, for example, based on the amount of fuel stored in advance in the facility 5A.

Based on the data acquired by the data acquisition unit 101, the load prediction unit 103 tentatively determines the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A. For example, the load prediction unit 103 operates the ventilation by an air conditioner or a ventilation device (not shown) based on the space where evacuees stay in the facility 5A, how they spend their time, the number of people, weather information, and the insulation performance of the facility 5A. The operating amount of the electrical load equipment 1 and the thermal load equipment 2, including the operating amount of the air conditioner and the operating amount of the electric light 1a, is calculated, and the predicted value of the electrical load and the predicted value of the thermal load are calculated. The predicted value of the electrical load and the predicted value of the thermal load calculated by the load prediction unit 103 are the predicted value of the load of the electrical load equipment 1 and the predicted value of the thermal load equipment 2 until the “energy duration target time” elapses. This is the predicted value of the load.

The equipment operation planning unit 104 operates the power supply equipment 3 and the heat source equipment 4 so as to satisfy the load of the electrical load equipment 1 and the load of the thermal load equipment 2 based on the predicted value of the load calculated by the load prediction unit 103. Generate a plan. That is, the equipment operation planning unit 104 generates an operation plan for the power supply equipment 3 and the heat source equipment 4 so as to satisfy the demand shown in the graph on the left side of FIG. 4(a) or FIG. 5(a). As a method for generating an operation plan in the equipment operation planning section 104, for example, any of the following methods may be used.
(1) A method of sequentially allocating the operating amounts of the power supply equipment 3 and the heat source equipment 4 on a rule-based basis according to preset rules so as to satisfy the predicted values of the electrical load and the thermal load.
(2) First, give an appropriate initial value for the operating amount of the power source equipment 3 and heat source equipment 4, and from there, perform repeated calculations to determine the operating amount of the power source equipment 3 and heat source equipment 4 that satisfies the load according to the algorithm. How to explore.
(3) A method of formulating an optimization problem to determine the operating amount of the power source equipment 3 and the heat source equipment 4 so that the total value of energy consumption of the power equipment 3 and the heat source equipment 4 is minimized, and finding an optimal solution.

The energy consumption calculation unit 105 calculates the energy consumption of the power supply equipment 3 and the heat source equipment 4 until the “energy duration target time” elapses based on the operation plan for the power supply equipment 3 and the heat source equipment 4 generated by the equipment operation planning unit 104. Calculate the consumption, i.e. the amount of fuel consumed. Energy consumption is calculated for each fuel type.

The load control consideration unit 106 develops a method for improving the ratio of electricity and heat consumption in the electrical load equipment 1 and the heat load equipment 2 so that the energy consumption calculated by the energy consumption calculation unit 105 decreases. think about. Specifically, the load control consideration unit 106 examines at least one operating method among the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A. The load control consideration unit 106 first calculates the amount of energy shortage based on the energy consumption calculated by the energy consumption calculation unit 105. Specifically, the load control consideration section 106 first obtains the remaining amount of energy obtained by the remaining energy amount obtaining section 102 for each fuel type. Next, the load control consideration section 106 compares the remaining amount of energy with the energy consumption amount calculated by the energy consumption amount calculation section 105 for each type of fuel, and calculates the amount of shortage. Next, the load control consideration unit 106 determines whether there is a shortage of energy based on the calculated shortage amount, and if there is a shortage, changes the operating method of the electric load equipment 1, heat load equipment 2, and facility 5A. Then, the changed operation method is transmitted to the load prediction unit 103. On the other hand, if there is no shortage of energy, the load control consideration unit 106 transmits the operating method of the electrical load equipment, the operating method of the thermal load equipment, and the operating method of the facility 5A at that time to the output unit 107. .

The output unit 107 outputs at least one of the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A considered by the load control consideration unit 106. The output unit 107 can output the information by displaying it on the display of a computer that constitutes the monitoring and control device 11, or by transmitting it to the facility manager's smartphone 17. Alternatively, the output unit 107 displays on a display device (not shown) installed in the facility 5A, or broadcasts a voice message within the facility 5A to inform the facility that the operation method of the facility 5A has been changed. Notify the administrator and evacuees.

Here, the hardware configurations of the monitoring control device 11 and the operation planning device 13 will be explained. The supervisory control device 11 and the operation planning device 13 are composed of processing circuits. The processing circuitry consists of dedicated hardware or a processor. The dedicated hardware is, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). A processor executes programs stored in memory. The storage unit 12 is composed of a memory. Memory can be nonvolatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, or EPROM (Erasable Programmable ROM), or disks such as magnetic disks, flexible disks, or optical disks. be.

FIG. 7 is a flowchart showing a flow when the operation planning device 13 according to the first embodiment outputs the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A. .

In step S01, the load prediction unit 103 uses the registered data 6 held by the monitoring and control device 11 and the data 7 to 9 acquired by the data acquisition unit 101 to determine the operating method of the electrical load equipment 1, the thermal load equipment 2 and the operation method of facility 5A are determined. The operation method of the facility 5A includes the space where evacuees are allowed to stay, how the evacuees spend their time during their stay, and the number of evacuees. That is, the load prediction unit 103 determines how many evacuees should stay in which spaces (areas), what time the evacuees should wake up and go to bed, etc. as an operating method for the facility 5A. This determines which area will be air-conditioned, so how many individual distributed air conditioners 1b that make up the electrical load equipment 1 will be operated, or the central heat source air conditioner 2a that makes up the heat load equipment 2. You can decide how many units to operate. Furthermore, since the electric light 1a is operated in the space (area) where the evacuees stay from the time they wake up until the time they go to bed, it is possible to determine how many hours and how many electric lights 1a are to be operated. Thereby, the load prediction unit 103 determines the operating method of the electrical load equipment 1 and the operating method of the thermal load equipment 2.

Next, in step S02, the load prediction unit 103 calculates the predicted value of the electric load and the predicted value of the thermal load in the future until the "target energy duration time" elapses, based on the operation method determined in step S01. do.

Next, in step S03, the equipment operation planning unit 104 calculates an operation plan for the power supply equipment 3 and the heat source equipment 4 so as to satisfy the predicted value of electric load and the predicted value of thermal load calculated in step S02. .

Next, in step S04, the energy consumption calculation unit 105 calculates the energy consumption, that is, the fuel consumption, based on the operation plan for the power supply equipment and heat source equipment calculated in step S03. Energy consumption is calculated for each fuel type.

Next, in step S05, the load control consideration unit 106 calculates the amount of energy shortage based on the energy consumption calculated in step S04. The load control consideration unit 106 calculates the amount of energy shortage by comparing the remaining amount of energy and the amount of energy consumed for each type of fuel.

Next, in step S06, the load control consideration unit 106 determines whether there is an energy shortage based on the amount of energy shortage calculated in step S05. If there is a shortage of energy, the process proceeds to step S07, whereas if there is no shortage of energy, the process proceeds to step S08.

In step S07, the load control consideration unit 106 determines the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and , change the operating method of facility 5A. Then, the operation method is updated to the changed operation method, and the process returns to step S02 to repeat the process.

On the other hand, in step S08, the output unit 107 outputs the operating method of the electric load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A at that time.

In addition, it has been explained here that the operation methods output by the load prediction unit 103 and the load control consideration unit 106 are the operation method of the electrical load equipment 1, the operation method of the heat load equipment 2, and the operation method of the facility 5A. However, it is not limited to that case. The operation method output by the load prediction unit 103 and the load control consideration unit 106 may be at least one of the operation method of the electric load equipment 1, the operation method of the thermal load equipment 2, and the operation method of the facility 5A. Similarly, the operating method output by the output unit 107 may be at least one of the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A.

As described above, in the first embodiment, the supervisory control device 11 controls the operation of the electrical load equipment 1 and the thermal load equipment 2 according to the operation method output by the operation planning device 13. Alternatively, the supervisory control device 11 presents the operation method outputted by the operation planning device 13 to the facility manager, receives corrections from the facility manager as necessary, and then Control the operation of 2. In this case, the facility manager may input the correction details directly into the computer that constitutes the monitoring and control device 11 using an interface, or may input the correction details from the smartphone 17.

In the first embodiment, the supervisory control device 11 generates an operation plan for power supply equipment and heat source equipment that improves the thermoelectric ratio of the load, and controls the load so as to achieve the target energy duration time. As a result, it is possible to achieve a remarkable effect that has not been seen in the past, such as being able to continue supplying energy for a desired period of time in the entire system that uses energy such as electricity and heat.

Furthermore, in the first embodiment, the supervisory control device 11 presents the operation method of the facility 5A output by the operation planning device 13 to the facility manager. Alternatively, the monitoring control device 11 displays or broadcasts on a display device within the facility 5A. In this way, the facility manager and evacuees are notified that the operation method of the facility 5A has been determined or changed, and are urged to be careful.

According to Embodiment 1, the thermoelectric ratio is improved in order to achieve continuous operation during the "target energy duration time" for which self-sustaining operation is desired. Since it is possible to obtain at least one of the methods of operating the electric load equipment 1, the method of operating the heat load equipment 2, and the method of operating the facility 5A that improve the thermoelectric ratio, the needs for continued operation in the event of a disaster can be obtained. It becomes possible to operate Facility 5A, which has achieved this goal.

Embodiment 2.
The monitoring control device 11 and the operation planning device 13 according to the present disclosure can be applied not only to a single facility 5A but also to the entire region 50 including a plurality of facilities 5B and 5C.

FIG. 8 is a configuration diagram showing the configuration of monitoring and control devices 11B and 11C provided in the combined heat and power system 100 according to the second embodiment. In the example shown in FIG. 8, a plurality of facilities 5B and 5C belong to the region 50. In the example of FIG. 8, one facility 5B and three facilities 5C are installed in the area 50, but FIG. 8 is just an example and is not limited to the example of FIG.

Each facility 5B and 5C is equipped with an electric load facility 1, a heat load facility 2, a power supply facility 3, and a heat source facility 4. In the example of FIG. 8, a monitoring control device 11B including an operation planning device 13 and a storage unit 12 is installed in a facility 5B that supervises the entire region 50. The facility 5B further includes a power supply equipment 3, a heat source equipment 4, a sensor 10, and a communication device 16. The configurations and operations of the operation planning device 13, storage unit 12, power supply equipment 3, heat source equipment 4, sensor 10, and communication equipment 16 are the same as in Embodiment 1, so their description will be omitted here. . However, in the second embodiment, the operation planning device 13 also determines the operating method of the electric load equipment 1 and the thermal load equipment 2 installed in the facility 5C, which is another facility, and the operating method of the facility 5C. This point differs from the first embodiment.

Each facility 5C has a different configuration from the facility 5B. Since the configurations of these three facilities 5C are the same, some illustrations are omitted in FIG. 8. In the facility 5C, a monitoring control device 11C, an entry/exit management system 18, an electric load equipment 1, a heat load equipment 2, a sensor 10, and a communication device 16 are installed. The supervisory control device 11C collects information on each piece of equipment in its own facility 5C, and provides the information to the supervisory control device 11B installed in the facility 5B.

That is, the monitoring control device 11C installed in the facility 5C does not have the operation planning device 13. Therefore, the operation planning device 13 of the facility 5B determines how to operate the electric load equipment 1 and the thermal load equipment 2, and how to operate the facility 5C. The monitoring control device 11C installed in the facility 5C operates the electric load equipment 1 and the thermal load equipment 2, and the facility 5C according to the operation method determined by the operation planning device 13 of the facility 5B.

In the example of FIG. 8, the power source equipment 3 and the heat source equipment 4 are installed in the same facility 5B as the supervisory control device 11B, but this is not important. What is important is that the power source equipment 3 and the heat source equipment 4 are installed in a location where energy can be supplied to the region 50 in the event of a disaster. Therefore, it is not necessary to particularly limit the installation positions of the power source equipment 3 and the heat source equipment 4, since the functions of the supervisory control device 11B may be provided so that the area 50 can be monitored and controlled in the event of a disaster. Further, for example, the supervisory control device 11B may provide functions on the cloud via the Internet 20.

FIG. 9 is a configuration diagram showing the configuration of the operation planning device 13 according to the second embodiment. As can be seen by comparing FIG. 6 and FIG. 9, in FIG. 9, among the functions of the operation planning device 13 shown in FIG. ing. That is, in the example of FIG. 9, the functions of the operation planning device 13 are divided into a first group 13a and a second group 13b. The first group 13a includes a load control consideration section 106. The second group 13b includes a data acquisition unit 101, a remaining energy acquisition unit 102, a load prediction unit 103, an equipment operation planning unit 104, an energy consumption calculation unit 105, and an output unit 107. . Further, the first group 13a and the second group 13b each have a first communication section 108a and a second communication section 108b in order to communicate with each other. Therefore, communication between the first group 13a and the second group 13b is performed via the first communication section 108a and the second communication section 108b.

Note that in the example of FIG. 9, only the load control consideration section 106 belongs to the first group 13a and is located outside the region 50, but the present invention is not limited to this case. That is, at least one of the data acquisition unit 101, the remaining energy acquisition unit 102, the load prediction unit 103, the equipment operation planning unit 104, the energy consumption calculation unit 105, and the output unit 107 is It may also be arranged outside the area 50 by making it belong to the group 13a.

In this way, the data acquisition unit 101, the remaining energy acquisition unit 102, the load prediction unit 103, the equipment operation planning unit 104, the energy consumption calculation unit 105, the load control consideration unit 106, and the output The portions 107 may be divided into a first group 13a and a second group 13b in any combination. Furthermore, the number of groups may be any number greater than or equal to two. That is, it is sufficient that at least one of these units 101 to 107 included in the operation planning device 13 belongs to the first group 13a, and at least one of the remaining units belongs to the second group 13b. Further, the remaining parts may belong to a third group, a fourth group, and so on.

In the first embodiment described above, the operation planning device 13 outputs the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facility 5A (see step S08 in FIG. 7). . In the second embodiment, the operation planning device 13 outputs the operating method for the facilities 5B and 5C or the area 50 instead of the operating method for the facility 5A.

FIG. 10 is a flowchart when the operation planning device 13 according to the second embodiment outputs the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the area 50. It is a flowchart which shows.

As can be seen by comparing FIG. 7 and FIG. 10, in FIG. 10, step S01A, step S07A, and step S08A are provided instead of step S01, step S07, and step S08 in FIG. . The operations in other steps are the same as those in FIG. 7, so they are indicated by the same reference numerals, and the explanation thereof will be omitted here.

In step S01A of FIG. 10, the load prediction unit 103 uses the registered data 6 held by the monitoring and control device 11 and the collected data 7 to 9 acquired by the data acquisition unit 101 to operate the electrical load equipment 1. method, how to operate the heat load equipment 2, and how to operate the facilities 5B and 5C or the area 50.

In step S07A of FIG. 10, the load control consideration unit 106 determines the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and , change the operating method of facilities 5B and 5C or area 50. Then, the process returns to step S02 and repeats the process.

In step S08A of FIG. 10, the output unit 107 outputs at least one of the current operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the area 50. Output one.

As described above, according to the second embodiment, an operation method is obtained in which the thermoelectric ratio is improved in order to achieve continuous operation during the "energy sustainment target time" for which self-sustaining operation of energy supply is desired to be continued in region 50. be able to. Note that the operation method is not limited to the operation method of the region 50, and for example, at least one of the operation method of the electric load equipment 1, the operation method of the heat load equipment 2, the operation method of the facilities 5B and 5C, or the region 50. There may be one operating method. This makes it possible to operate the facilities 5B and 5C and the region 50, which meet the needs for continued operation in the event of a disaster.

Embodiment 3.
The operating methods described in the first and second embodiments above may be evaluated using a preset evaluation function and determined as an optimization problem that minimizes the evaluation value. In Embodiment 3, this case will be described below. Here, a case where the third embodiment is applied to the configuration of the second embodiment shown in FIG. 8 will be described as an example.

An example of an evaluation function is the effect on facilities 5B and 5C or area 50 due to changes in the operating method of electrical load equipment 1, the operating method of thermal load equipment 2, and the operating method of facilities 5B and 5C or area 50. An example is an evaluation function that is converted into an index. As a specific example, if the operation of air conditioners such as the individual distributed air conditioner 1b and the central heat source air conditioner 2a is restricted, the indoor thermal environment deteriorates. In the summer, the indoor temperature and humidity rise, making it a hot environment. Also, in the winter, the indoor temperature drops and the environment approaches a cold environment. Such an influence index indicating thermal comfort can be used as an index of an evaluation function. In this way, the impact index is an indicator of the degree of impact.

In addition to thermal comfort, the impact index may also be the comfort of the light environment, the percentage of time that the equipment can be used out of the "target energy duration", or the measurement data 7 of the sensor 10, etc. good.

Alternatively, if a contract has been established in which the manager of facility 5B or 5C pays a monetary penalty to the owner or user of facility 5B or 5C, the amount of penalty payment may be used as an index of the evaluation function. Good too. For example, changing the operating method of the electric load equipment 1, the heat load equipment 2, and the facilities 5B and 5C or the area 50 will have some effect. At that time, it is assumed that a contract has been established in which the facility manager pays a financial penalty to the facility owner or user, depending on the magnitude of the impact. In such a case, the amount of penalty payment may be used as an index of the evaluation function.

FIG. 11 is a flowchart when the operation planning device 13 according to the third embodiment outputs the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the region 50. It is a flowchart which shows.

Similarly to FIG. 10, in step S01A, the load prediction unit 103 uses the registered data 6 held by the monitoring and control device 11 and the collected data 7 to 9 acquired by the data acquisition unit 101 to estimate the electric load equipment. 1, the heat load equipment 2, and the facilities 5B and 5C or the region 50 are tentatively determined. At this time, as described above, the load prediction unit 103 first determines the operating method of the facilities 5B and 5C or the region 50, and then determines the operating method of the electrical load equipment 1 and the thermal load equipment 2, for example.

Next, in step S10, the load control consideration unit 106 formulates an optimization problem to minimize the influence index based on the operation method determined in step S01A. Alternatively, when using the penalty payment amount as the evaluation function, the load control consideration unit 106 formulates an optimization problem to minimize the penalty payment amount instead of the influence index.

The optimization problem has a constraint that the amount of energy consumed is less than or equal to the remaining amount of energy when the "target energy duration time" has elapsed, and the result of optimization is Ensure that continuity can be achieved.

Next, in step S11, the load control study unit 106 solves the optimization problem formulated in step S10. There are countless ways to operate the electric load equipment 1, heat load equipment 2, facilities 5B and 5C, or region 50, in which the energy consumption becomes less than the remaining amount of energy when the "target energy duration time" elapses. . However, by the optimization problem formulated in step S10, a point where the influence index is minimized is determined, and the operation method for electric load equipment 1, heat load equipment 2, facilities 5B and 5C or region 50 is determined as the best one. is output.

According to the third embodiment, the viewpoint of the index given as the evaluation function among the operation methods that improve the thermoelectric ratio so as to achieve continuous operation during the "energy duration target time" for which self-sustaining operation is desired to be continued. The optimal method can be obtained from The operating method is at least one of the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, the operating method of the facilities 5B and 5C, or the area 50. This makes it possible to operate the facilities 5B and 5C and to operate the region 50, which meet the needs for continued operation in the event of a disaster.

Embodiment 4.
A plurality of energy supply target times each having a time length shorter than the "energy sustaining target time" described in the first to third embodiments above may be calculated, and each optimal solution may be output. In Embodiment 4, this case will be described below. Here, a case where the fourth embodiment is applied to the configuration of the second embodiment shown in FIG. 8 will be described as an example.

FIG. 12 is a flowchart when the operation planning device 13 according to the fourth embodiment outputs the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the area 50. It is a flowchart which shows. The difference between FIG. 11 and FIG. 12 is that in FIG. 12, steps S13, S14, and S15 are added, and step S16 is provided instead of step S08A.

Step S13 is provided between step S01A and step S10. Step S14 is provided between step S11 and step S16. Step S15 is a step to which the process proceeds if the determination in step S14 is "NO". Step S16 is a step to which the process proceeds if the determination is "YES" in the process of step S14.

The operations in other steps are the same as those in FIG. 11, so they are indicated by the same reference numerals, and their explanations will be omitted here.

In FIG. 12, in step S13, the load control consideration unit 106 sets a set of energy supply target times. When setting a set of energy supply target times, each energy supply target time is set to be equal to or shorter than the "energy duration target time". For example, when the "energy duration target time" is 72 hours, there is a method of setting the energy supply target time in 6-hour increments, such as 72 hours, 66 hours, 60 hours, . . . , 6 hours. Note that the time increments of the energy supply target time do not need to be equal intervals, and any time interval, arbitrary number of points, and time can be set.

In step S14, the load control consideration unit 106 determines whether the processes in steps S10 and S11 have been performed for all energy supply target times. If there is a remaining energy supply target time, the process proceeds to step S15; otherwise, the process proceeds to step S16.

In step S15, the load control consideration unit 106 sets the next energy supply target time, returns to step S13, and solves the optimization problem again.

In step S16, the output unit 107 outputs a plurality of candidates for the operating method of the electric load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the region 50.

FIG. 13 is a graph plotting influence indicators of optimization results for a plurality of energy supply target times in the operation planning device 13 according to the fourth embodiment. In FIG. 13, the horizontal axis indicates the target energy supply time, and the vertical axis indicates the influence index. In FIG. 13, the values of the target energy supply time and the influence index are plotted on a plane representing the relationship between the target energy supply time and the influence index. Each plot corresponds to each energy supply target time set as 72 hours, 66 hours, 60 hours, . . . , 6 hours. Further, each plot is associated with the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the area 50. It is assumed that if each operation method is executed at each energy supply target time, the influence index of the point corresponding to the plot of the graph and the continuation of the energy supply target time will be realized. The operation planning device 13 may be configured to express the optimization result in a graph as shown in FIG. 13 and present it to the facility manager so that he can select which operation method to execute. A method for the facility manager to select an operation method will be explained using FIG. 14.

FIG. 14 is a diagram showing a comparison between operation method A and operation method B among the plurality of operation methods in the graph of FIG. 13. In FIG. 14, the influence index of operation method A is Ea, and the energy supply duration time is ta. On the other hand, the influence index of operation method B is Eb, and the energy supply duration is tb. Here, the magnitude relationship between the influence indices Ea and Eb is Ea>Eb. Moreover, the magnitude relationship between the energy supply times ta and tb is ta>tb. As can be seen from this, operation method A allows a longer energy supply time, but has a large impact index. On the other hand, in operation method B, the energy supply time is shortened, but in return, the influence index can be reduced. Facility managers can determine how to set equipment and facility operation methods while looking at the trade-off relationship between impact indicators and energy supply duration. In the event of a disaster, there are variations in impact indicators, etc., and the situation is expected to change from moment to moment. However, according to the fourth embodiment, even in such a situation, the facility manager can manage the electrical load equipment 1, the heat load equipment 2, the facilities 5B and 5C, or the area 50 with the support of the monitoring and control device 11. You can decide how to set up the operation method.

According to the fourth embodiment, the facility manager can select an operation method for improving the thermoelectric ratio while looking at the trade-off between the influence index given as an evaluation function and the energy supply duration time. That is, the facility manager selects the operating method of the electrical load equipment 1, the operating method of the thermal load equipment 2, and the operating method of the facilities 5B and 5C or the area 50 while considering the trade-off. be able to. This makes it possible to flexibly change the operation of the facilities 5B and 5C according to the situation at the time of a disaster.

Embodiment 5.
The equipment to be managed by the supervisory control device 11 shown in the first to fourth embodiments above may further include power storage equipment, heat storage equipment, and renewable energy power generation equipment.

FIG. 15 is a diagram showing a connection relationship among electric load equipment 1, thermal load equipment 2, power supply equipment 3, heat source equipment 4, power storage equipment 14, and heat storage equipment 15 in combined heat and power generation system 100 according to Embodiment 5.

As shown in FIG. 15, power storage equipment 14 is connected between power supply equipment 3 and electrical load equipment 1. The power storage facility 14 stores electrical energy and outputs it when necessary. The power storage facility 14 stores electricity from an external power source (not shown) or electricity from the power source facility 3 in advance during normal times. Moreover, the power storage facility 14 stores electricity that is not used immediately among the electricity generated after a disaster occurs. The power storage equipment 14 includes, for example, a storage battery. In the event of a disaster, the power storage equipment 14 contributes to satisfying the demand for electricity in the electrical load equipment 1 by discharging the stored electricity at the necessary time.

As shown in FIG. 15, the heat storage equipment 15 is connected between the heat source equipment 4 and the heat load equipment 2. The heat storage facility 15 stores thermal energy and outputs it when necessary. The heat storage facility 15 stores heat in advance during normal times. Furthermore, the heat storage facility 15 stores waste heat that is not used immediately among the waste heat generated after a disaster occurs. The heat storage equipment 15 includes, for example, a storage tank, a heat storage tank, a hot water tap, and the like. In the event of a disaster, the heat storage equipment 15 contributes to satisfying the heat demand of the heat load equipment 2 by dissipating the stored heat at the necessary time.

In the fifth embodiment, the power supply equipment 3 includes a renewable energy power generation equipment 32. However, the configuration and operation of the power supply equipment 3 itself are the same as the power supply equipment 3 shown in the first to fourth embodiments. The renewable energy power generation facility 32 generates power using renewable energy. Renewable energy includes, for example, solar power, wind power, hydropower, geothermal power, and the like. The renewable energy power generation equipment 32 includes, for example, a solar panel that generates solar power, a wind power generator that generates wind power, and the like. Since the amount of power generated by the renewable energy power generation equipment 32 is affected by weather conditions, the amount of power generated fluctuates.

FIG. 16 is a diagram illustrating an example of reducing the amount of energy used and extending the target energy duration time by changing the thermoelectric ratio in the combined heat and power system 100 according to the fifth embodiment.

As shown in the graph on the left side of FIG. 16(a), before the improvement, there is a demand for electricity D1 and a demand for cold water D2. As shown in the graph on the right side of FIG. 16(a), the electricity demand D1 is generated by power generation using fuel from the power supply equipment 3 represented by G1, discharge from the power storage equipment 14 represented by BA, and renewable energy represented by RE. I am satisfied with the power generation by the energy generation equipment 32. The demand for chilled water D2 is satisfied by converting waste heat G2 resulting from power generation of the power supply equipment 3 into chilled water using an exhaust heat injection type absorption refrigerator or the like that constitutes the heat source equipment 4. Among the waste heat generated by the power generation of the power supply equipment 3, the waste heat G3 that is not used for generating cold water is unnecessary and is therefore discarded.

In the event of a disaster, in order to reduce fuel consumption as much as possible, it is desirable to supply as much power as possible from the renewable energy power generation equipment 32. However, since the amount of power generated by renewable energy fluctuates depending on weather conditions and other factors, the amount of power generated may suddenly decrease dramatically. In such a situation, by discharging electricity from the power storage equipment 14 to compensate for fluctuations in renewable energy, the operation of the electrical load equipment 1 etc. can be continued without causing a failure or power outage in the electrical load equipment 1 etc. . For this reason, it is desired that the power storage equipment 14 has a remaining amount of electricity so that it can receive electricity when needed.

Therefore, as shown in FIG. 16(b), the thermoelectric ratio is improved so as to reduce the electricity demand D1 and increase the cold water demand D2 compared to before the improvement. The reduction in electricity demand D1 is used to reduce the amount of discharge from power storage equipment 14. This allows the power storage equipment 14 to have a remaining amount of electricity so that it can receive electricity when needed.

Furthermore, the increase in the demand for cold water D2 is satisfied by converting at least a portion of the wasted waste heat G3 into cold water. In this way, as long as the increase in the demand for cold water D2 can be covered by the discarded waste heat G3, the amount of fuel consumed by the power source equipment 3 and the heat source equipment 4 will not increase.

In the fifth embodiment, in this way, the waste heat G3 that was wasted is effectively utilized to improve the thermoelectric ratio so as to maintain the remaining charge of the power storage equipment 14 as much as possible. Thereby, it is possible to provide a system that can respond to sudden fluctuations in renewable energy while satisfying demand while leaving the remaining amount of charge in the power storage equipment 14.

According to this configuration of the fifth embodiment, the method of operating the electric load equipment 1, the heat load equipment 2, the facilities 5B and 5C, or the area 50 for improving the thermoelectric ratio is implemented, and the power storage equipment 14 and the heat storage equipment 15 are and can be operated to maximize the use of renewable energy. Therefore, in the event of a disaster, it is possible to change the operation of the facilities 5B and 5C or the region 50, which effectively utilizes renewable energy.
