Description

 {} {} Demand resource management system in conjunction with renewable heat obligation (RHO) system and service method using it

- Temperature control technology: Temperature control technology through communication protocol of geothermal heat pump

- Surrounding Outside Temperature: If you use the weather forecast of the Korea Meteorological Agency or a GPS-based smartphone, you can acquire the accurate weather information of the present location of the building and adjust the indoor temperature of the building where the geothermal system is installed.

- Energy management technology: Smart grid technology that combines information and communication with energy efficiency and demand response services

- Sensing technology: Measures the temperature and flow rate of the inlet and outlet of the geothermal heat pump and uses the data as a factor that can be used to control the heat pump.

In the building sector, the renewed and renewed thermal energy due to the mandatory RHO and the dissemination of the equipment are accompanied by consumption of another energy source. That is, by using new energy sources such as electrical energy in direct fossil fuel combustion, it can affect power supply during the winter season and peak load. Of course, when the geothermal heat pump system is used in the summer season, energy consumption is reduced rather than using direct air conditioner. However, when electric power reserve is insufficient due to electric energy, We propose demand resource operation system and service that can save cost.

Controlling the room temperature in a shared space, such as a multi - person building, is very important in terms of maintenance of energy costs and occupants' comfort in terms of building management. If we use the geothermal heat, which is one of the new and renewable thermal energy sources, to control the room temperature by controlling the indoor temperature in conjunction with the outdoor temperature, we will propose it to be effective in maintaining the comfort level with low energy use.

RHO (new and renewable thermal energy), which will be the catalyst for renewable thermal energy activation, will be introduced in January 2016. According to the step-by-step expansion plan, the first phase (2016-2020) The rate of heat energy adoption is 10%. In the second phase (2020 ~ 2024), the obligation rate for newly built buildings over 5,000m² is increased by 1% every year. It is 11% in 2020, 12% in 2021, 13% in 2022, 14%, and 15% in 2024. The third phase (2025 ~ 2030) is for new buildings with a total floor space of more than 3,000m², and the government announced that it will increase by 1% every year to the final 20%.

In the building sector RHO, the geothermal heat was set at 1.0, the solar heat was set at 0.7, and the fuel cell was set at 2.0. In this way, equity was secured when the system was implemented and a supply certificate analyzing the technological feasibility, technology development level, It is known that the weighting is established and the application of the scheme for establishing the supply certificate weight is included.

In Korea, the power reserve ratio of the Korea Power Exchange should normally remain at 10% during the peak period of power use, but it is not yet 5%.

In order to prevent accidents caused by power shortages and to reduce the cost of additional power plants, KEPCO and KEPCO are promoting real-time DR (Demand Response).

Real-time DR is a technology that forms the two axes of Smart Grid together with electric power trading system that sells electric power developed through renewable energy. It adopts demand / supply concept for power generation and electric power use, It is a system that compensates for the power loss when manual or automatic power reduction is considered as the core of power energy management technology.

Demand response means that when electricity demand increases, the consumer reacts to reduce the use of electricity, and the number of households is as large as the number of households. In particular, a simple electricity tariff system does not motivate the consumer to voluntarily respond. Therefore, the US and Europe will generate basic demand responses based on a variety of tariffs, while the power network operator will incur a strong incentive to respond to demand And more active demand response services through the sale of demand in the market. Most importantly, it is a service technology that transmits power network information to a customer to reduce the demand response, that is, the use of electric power equipment in the customer, and to make transparent compensation for it.

However, in general, the amount of load that can be reduced at the time of peak load is not large in terms of individual consumers, and therefore, the amount of compensation is so small that few consumers participate with interest. The way to increase this is the expansion of Automated Demand Response (AutoDR). In other words, when the AutoDR signal is sent to the electric network operator or the demand management operator, it automatically receives the signal to reduce the load on the customer.

There is a study of the OpenADR Alliance (OpenADR Alliance) that can activate up to 20% of the maximum generation resources when activating AutoDR.

Geothermal Heat Pump Intelligent Demand Management Operational services can be controlled in real-time in conjunction with real-time demand management systems via AutoDR, giving the user or operator the opportunity to benefit from reduced power energy and additional incentive monetary compensation. In addition, it is expected that more RHOs will benefit from more energy savings and benefits if multiple geothermal heat pump systems are integrated with integrated intelligent demand management services.

If the RHO trading market is formed, reliable data can be provided to buyers, sellers and their respective agencies or public authorities for compliance with RHO.
