Abstract

Systems and methods for managing power supplied over an electric power grid by an electric utility and/or other market participants to multiple power consuming devices, each of which having a Power Supply Value (PSV) associated with its energy consumption and/or reduction in consumption. Power flow to the power consuming devices is selectively enabled and disabled, or power-reduced thereto, by one or more controllable devices controlled by the client device. Power control messages from a controlling server indicate amounts of electric power to be reduced and an identification of at least one controllable device to be instructed to disable or reduce a flow of electric power to one or more associated power consuming devices.

Claims (40)

1. A system for managing an electric power grid, comprising:

at least one server, including a processor and a memory, wherein the at least one server receives a power control command requiring a reduction of an amount of power consumed by at least one power consuming device;

at least one client device in network communication with the at least one server;

wherein the at least one server issues a power control message to the at least one client device in response to the power control command;

wherein the power control message causes the at least one client device to adjust a setting of the at least one power consuming device, and wherein the adjustment of the setting of the at least one power consuming device results in a reduction of power consumed by the at least one power consuming device;

wherein a power supply value (PSV) for the at least one power consuming device is generated;

wherein the PSV is a value relating to a reduction in consumed power based on duty cycles and/or set points over a preset period of time for the at least one power consuming device participating in at least one load control event; and

wherein the duty cycles and/or the set points of the at least one power consuming device are determined at the at least one client device.

2. The system of claim 1 , wherein the at least one server generates a total energy savings for the at least one load control event.

3. The system of claim 1 , wherein the at least one server automatically aggregates total energy savings for a plurality of load control events.

4. The system of claim 1 , wherein the power control message includes information relating to a change of state for the at least one power consuming device, an alert relating to the at least one power consuming device, and/or a status for the at least one power consuming device.

5. The system of claim 1 , wherein the at least one power consuming device includes at least one heating, ventilation, and air conditioning (HVAC) device.

6. The system of claim 1 , wherein the amount of power available for the at least one power consuming device is determined based on weather or climate information for a location where the at least one power consuming device is located.

7. The system of claim 1 , wherein the at least one client device includes at least one smart thermostat.

8. A system for managing an electric power grid, comprising:

at least one server, including a processor and a memory, wherein the at least one server receives a power control command requiring a reduction of an amount of power consumed by at least one power consuming device;

at least one client device in network communication with the at least one server;

wherein the at least one server issues a power control message to the at least one client device in response to the power control command;

wherein the power control message causes the at least one client device to adjust a setting of the at least one power consuming device, and wherein the adjustment of the setting of the at least one power consuming device results in a reduction of power consumed by the at least one power consuming device;

wherein the at least one server or the at least one client device generates a value relating to a reduction in consumed power based on duty cycles and/or set points for the at least one power consuming device participating in at least one load control event;

wherein the duty cycles and/or the set points of the at least one power consuming device is determined at the at least one client device or at the at least one server; and

wherein the at least one server generates a total energy savings for one of the at least one load control event based on the value relating to the reduction in consumed power for each of the at least one power consuming device.

9. The system of claim 8 , further comprising a database for storing information including the amount of power available for each of the plurality of power consuming devices and/or an amount of power to be reduced to the plurality of power consuming devices.

10. The system of claim 8 , wherein the at least one server aggregates total energy savings for a plurality of load control events to generate cross-event total energy savings.

11. The system of claim 8 , wherein the at least one client device includes at least one load control switch.

12. The system of claim 8 , wherein the at least one client device transmits at least one initiation message to the plurality of power consuming devices to initiate the reduction of the flow of power to the at least one of the plurality of power consuming devices.

13. The system of claim 8 , wherein the power control message includes information relating to a change of state for the plurality of power consuming devices, an alert relating to the plurality of power consuming devices, and/or a status for the plurality of power consuming devices.

14. The system of claim 8 , wherein the plurality of power consuming devices includes at least one heating, air-conditioning, and ventilation (HVAC) device.

15. A system for managing an electric power grid, comprising:

at least one server, including a processor and a memory, wherein the at least one server receives a power control command requiring a reduction of an amount of power consumed by at least one power consuming device;

at least one client device in network communication with the at least one server;

wherein the at least one server issues a power control message to the at least one client device in response to the power control command;

wherein the power control message causes the at least one client device to adjust a setting of the at least one power consuming device, and wherein the adjustment of the setting of the at least one power consuming device results in a reduction of power consumed by the at least one power consuming device;

wherein the at least one server or the at least one client device generates a value relating to a reduction in consumed power of the at least one power consuming device participating in at least one load control event; and

wherein the at least one client device transmits an acknowledgement for participation of the at least one power consuming device in the at least one load control event in real time or near real time.

16. The system of claim 15 , further comprising a database for storing information including the amount of power available for the at least one power consuming device and/or the amount of power to be reduced to the at least one power consuming device.

17. The system of claim 15 , wherein the at least one client device includes at least one load control switch.

18. The system of claim 15 , wherein the at least one client device includes at least one smart thermostat.

19. The system of claim 15 , wherein the at least one power consuming device includes at least one heating, ventilation, air conditioning (HVAC) device.

20. The system of claim 15 , wherein the at least one server generates a total energy savings for one of the at least one load control event based on the value relating to the reduction in consumed power for each of the at least one power consuming device.
