  • server 105 and the clients 110 communicate through a network which allows to communicate the intention to turn on the appliance/switch associated to a given client; typically, the network 115 is implemented by means of a medium which is able to carry electronic control signals, for example by means of conveyed waves, which is a common method to propagate low voltage control signals over regular electrical wires (e.g.
  • the server 105 consists of a computer being formed by several units that are connected in parallel to a system bus 120.

  • An arbiter 180 manages the granting of the access with mutual exclusion to the system bus 120.
  • clients 110 are removable devices which can be interposed between the power network and the corresponding appliances without any modifications needed to the wiring system or to the appliance itself.
  • client 110 is a removable device which can be interposed between an electrical device (e.g. a house appliance) and the server 105 (not shown in this Figure) e.g. as female/male plug adaptor.
  • an electrical device e.g. a house appliance
  • server 105 not shown in this Figure
  • client 110 power request broker Devices
  • Optional control 201 can be used to set and adjust the value of expected power load which will be required by the corresponding device once it has been connected. This value will be communicated to the PED in order to get consensus to the new requested power load. Manual adjustment it's the most simple way of setting the POD, but more advance method and system could be implemented instead, as better explained later.
  • Fig 2b shows a schematic diagram of the main components of POD.
  • Modules 203 and 205 are needed to communicate with server 105 over network 115.
  • CW sender 203 sends ⁇ ID> and/or ⁇ needed load> CW signal to PED.
  • CW receiver 205 awaits the response by PED 105.
  • Conveyed Waves seems to be the best solution for transmitting information between POD and PED; they can transmit low-voltage control signals over power lines, however alternative transmission solutions might be implemented as discussed.
  • Module 207 causes the circuit to close and provides the requested power to the associated device, once consensus by the PED has been obtained. In this described embodiment a relais module is used, but those skilled in the art will easily understand that other equivalent solutions could be used instead.
  • a sensor 209 is needed to detect that a new power load is being requested and triggers the transmission of the request to the PED.
  • sensor 209 can be more sophisticated and automate handshaking renewal, to handle situations where permanent-connected appliances gets turned on, or where appliances with varying power consumption levels are to be managed.
  • Such sensor can detect that the appliance is being powered on, i.e. a significant power variation is demanded from the appliance, in addition to the stand-by current.
  • the measurement can be obtained, for example with a current meter which is able to report the dynamic resistance variation.
  • More complex embodiment are possible for the POD which could be provided with additional modules, e.g. an internal memory to keep track of previous requests or for storing useful information on the associated appliance consumption needs.
  • a more advanced embodiment of the POD could implement an introspection feature which is able to inspect the associated appliance in order to detect its factory load characteristics. This would avoid the manual initial setup.
  • Another possible implementation is to embed the POD directly into the appliance.
  • Many modern electrical appliances include electronic control logic (dishwashers, washing machines, microwave ovens, all electronic appliances, etc) , and hence can be easily extended to host such additional POD logic.
  • Being POD embedded in the appliance greater interaction among POD and appliance can be implemented. For instance, it is not only possible to introspect factory parameters about standard power needs (e.g. static info like peak needs) but to introspect current appliance settings (e.g. amount of heat / cold needed) and to estimate the more accurate electrical power needs, according to such current settings. In this way, when POD sends a power-on request to the PED, it can be much more precise about the real appliance power needs.
  • An additional possible feature is the ability to detect varying power needs, for appliances which have a time-varying load demand.
  • POD can exchange control signals with PED, not only for power on requests, but in general, for all the significant status variation needs. For example, during a 2 hours cycle of a typical washing machine, there are repeated activities which require a modest power load (300-500 watts during washing or wringing time), in addition to a couple to time-delimited activities which however requires intensive power load (1-1.3 kWatts, for water heating, but just 5 to 10 minutes) .
  • POD Being embedded POD able to interact with both appliance internal state, and with PED for consensus, it can act as a real-time broker and make more frequent, power-accurate requests to the PED, and figure out if the appliance can switch among its consumption status, or if it has to wait for a consensus.
  • the POD is able to introspect (e.g. with the power request detection sensor) the appliance status, it is possible to automate interaction with PED, without specific human intervention. So, not only the user can interact through the appliance interface directly, without the need to interact with switches of the electrical home system, but it is also covered the scenario where "time” or “events” (through a timer/scheduler or a thermostat) are automatically orchestrating appliances.
  • a thermostat tries to trigger the air conditioning on, because a time/temperature threshold is reached, but at the same time a dishwasher was operating; also in this unattended scenarios, PODs and PED will prevent unattended overload situations, load activation may be denied or deferred, and messages logged. Also, being PODs able to optionally introspect or even interact with appliance load characteristics and its power settings, POD can send more accurate power load demand requests, when interacting with PED. This can be beneficial both in term or maximizing usage of total available load among house appliances, and in term of time-orchestration of time-varying loads for dynamic appliances .
  • PODs 110 are connectable to one or more appliances 301 on one side and to the PED through the electrical wires on the other side.
  • PED 105 is normally connected to the meter/switch 303 and to one or more PODs 110.
  • PED 105 provides a functionality which can range from a mere alerting service to a proper control and management of the electricity consumption within the house.
  • PED could be located anywhere between the main meter/switch, normally provided by the electrical distribution company, and the household appliances or, more in general, the electrical devices to be managed. Its preferred location is however inside the apartment itself, near the remainder of the main internal switches (normally used to section the electrical network between e.g. 10 and 16 A loads) .
  • the meter/switch 303 can be either a legacy electro-mechanical model or an electronic one.
  • the role of the PED is to give consensus, whenever a new appliance is being turned on.
  • each POD is not only able to send an ID signal to the PED, but is also able to receive a consensus signal, over the wire. Once such consensus signal is received (e.g. a CW signal) , it will then activate the power to the associated appliance, acting in a "relais" mode as described with reference to Fig 2b above.
  • consensus signal e.g. a CW signal
  • the advantage of this solution is that no direct wiring is needed from PED to PODs, as consensus signals are routed through junctions to the proper switch (e.g. " ⁇ switchIDXack>" or " ⁇ switchIDXnoack>”) .
  • junction wires to PODs are always powered (as in today's layouts) and it's the switch that, working in relais-mode, powers the appliance when consensus is got from PED.
  • PODs really act as real power switches with the difference that power-on happens only if they receive consensus from the PED.
  • the only information a POD is able to transmit over the wire is a unique signal ID (e.g. unique deviation out of a base CW frequency, or a unique resistance) each time the corresponding appliance or device is switched on (for either turning on lights or enabling an appliance) .
  • a unique signal ID e.g. unique deviation out of a base CW frequency, or a unique resistance
  • PED receives signal IDs from POD, and have a static table where, for each ID, it lists the associated known load. PED is normally connected to a power meter, so it's instantly aware of the current total load in use, it's able to forecast if, giving power to the wire to which the specific POD is connected, the total power threshold would be violated, and in this case it won't activate the specific wiring, that connects
  • every POD (for which a sensible load is known to be possibly connected) must have a direct wiring which connects it to the PED; such wire is usually not powered (it only allows ID signal exchange) and gets powered with 220/110 voltage, only if consensus is given from PED.
  • slave PEDs could be added in the intermediate junctions.
  • PED must know how much electrical power a POD will absorb, and this information can be statically defined in PED configuration, although it could optionally be self updated as consensus is given (usage statistics) , with an optional time-based reset policy.
  • a limitation of this scenario is the static load pre-configuration, and the need to direct PED-POD wires, or of intermediate PEDs.
  • the advantage is the limited logic needed in the POD.
  • POD in addition to be able to send its ID (sender) and to receive a consensus signal from PED (CW receiver) , might be also able to remember the last required load from the served appliance.
  • the amount of power required from each POD may not be known a priori from PED, but PODs are able to remember last used load. PED in this case, must only reply to the given switch ID which made the request, that the requested amount of load is available, as it won't exceed the total available load. So for instance, ⁇ ID> and ⁇ needed power>, are communicated from POD to PED, and there is no more need of a lookup on a static table.
  • the method begins at start block 401 and passes to block 403 where a new request for power load is detected by the client (POD) 110.
  • the request is then sent to the server (PED) 105 at step 405.
  • the PED processes the request according to a predetermined process and replies to the POD (step 407) .
  • the expected new requested load could be estimated by the system, e.g. by means of a look-up table by the PED or directly communicated by the POD 110. If the addition of the expected new load to the current one does not exceed the predetermined maximum allowed power of the meter/switch 303 then authorisation is given to POD 110 and supply of power is granted (step 409) and control goes to step 411 where e.g.
  • the circuit is closed by means of a relais; otherwise the control goes back to step 403; in this case alternative recovery solution is implemented (not shown on the diagram) , the request is suspended but the rest of the system does not suffer of any breakdown as with prior art systems.
  • the range of possible recovery solutions is very broad and could be a simple communication to the client (and finally to the user) that the new request is not receivable (e.g. by means of an alarm) or a more complex management of the power load depending on the logic contained in the PODs 110.
  • the control messages exchanged between the PED and the plurality of PODs 110 can be of several different types, depending on the level of complexity of each POD.
  • the PED 110 If the POD 110 is only able to send its unique identity, then the PED will need to directly control the electrical power which has to be granted to the client switch, as the client is not able to receive a consensus signal; this has implications in the electrical wiring, as star-wiring form PED to POD would be needed.
  • the POD is also able to receive a consensus control signal (e.g. a CW receiver is implemented) , then the set of messages exchanged from PED and PODs could be more complex and PED could avoid a direct control of the electrical power supply to PODs, thus delegating the PODs for the activation of the electrical load, once the consensus signal is issued by the PED.
  • a consensus control signal e.g. a CW receiver
  • POD 110 may also be able to communicate additional attributes of the controlling load, so that it could be able e.g. to report the expected load demand, according to current load settings or last/historical power demand for the controlling load; this information allows PED to operate in a more dynamic way, without the need of manual power-usage settings for the different controlling client loads.
  • additional attributes of the controlling load so that it could be able e.g. to report the expected load demand, according to current load settings or last/historical power demand for the controlling load; this information allows PED to operate in a more dynamic way, without the need of manual power-usage settings for the different controlling client loads.
  • more complex recovery actions could be implemented, e.g. one of the currently connected appliances or devices could be disconnected to allow the new request to be satisfied, according to a predefined priority list.
  • the big advantage of the proposed solution is the fact that the PODs are independent and can be interposed between any appliance and the server (PED) without any need to modify the appliance itself and the wiring system.
  • the PODs can be tuned to a predefined power load which will be communicated to the server (PED) when the corresponding appliance will be switched on (or better when an attempt/request to switch on is detected) .
  • This is not the most flexible solution, as it requires the intervention of a user which also has the responsibility of setting the device to the proper thresholds.
  • the PODs can be provided with more "intelligence" as required, e.g. it could be possible for a POD to learn the required maximum load of the associated device or to maintain a memory of previously requested loads. From the PED point of view this does not make a big differences as, in any case, what is received from POD is a request for a precise power load and the response by the PED is tailored on this value; accuracy of the system is strictly dependent by precision of the POD request.
  • Another variable which must be taken into account is the information made available by the appliance connected to the POD. Modern appliances could provide a wider range of information which could broaden the possible actions of the POD.

Abstract

La présente invention se rapporte à une solution pour réguler et gérer un usage de la puissance électrique domestique afin de prévenir toute interruption indésirable du service. Selon un mode de réalisation préféré de la présente invention, un dispositif amovible est proposé, qui peut être placé entre n'importe quel appareil électrique et le compteur électrique afin de prévenir et de gérer une interruption de puissance électrique dans le circuit électrique d'une habitation. Le dispositif interagit avec un serveur qui surveille et régule l'usage total de la puissance électrique du circuit ; le serveur autorise de nouvelles requêtes de consommation électrique par l'un quelconque des appareils électriques uniquement si ces requêtes peuvent être satisfaites sans excéder une charge maximum prédéterminée autorisée du circuit.
