Abstract

A client device manages consumption of power supplied by an electric utility to power consuming devices. Power flow to the power consuming devices is selectively enabled and disabled by one or more controllable devices controlled by the client device. The client device receives a power control message from a load management server. The power control message indicates at least one of an amount of electric power to be reduced and an identification of at least one controllable device to be instructed to disable a flow of electric power to one or more associated power consuming devices. Responsive to the power control message, the client device issues a power management command to one or more controllable devices under the client device'"'"'s control. The power management command causes the one or more controllable devices to disable a flow of electric power to the one or more associated power consuming device.

Claims

1. A method for managing an electric power flow within an electric power grid, comprising:

a client device receiving a power control message from a load management server, the power control message indicating at least one of an amount of electric power to be reduced and an identification of at least one controllable device to be instructed to disable the electric power flow to at least one associated power consuming device;

the client device issuing a power management command to the at least one controllable device, the power management command causing the at least one controllable device to disable the electric power flow to the at least one associated power consuming device to provide a reduction in consumed power; and

generating measurement and verification data corresponding to the reduction in consumed power.

2. The method of claim 1, further comprising generating a power supply value (PSV) corresponding to the reduction in consumed power.

3. The method of claim 1, further comprising communicating a report message to the load management server, the report message including an indication of an amount of power consumed by the at least one associated power consuming device corresponding to the measurement and verification data.

4. The method of claim 3, wherein the report message indicates a compensation associated with the reduction in consumed power.

5. The method of claim 4, wherein the compensation includes at least one of:

capacity compensation, energy compensation, operating reserves compensation, ancillary services compensation, compensation for other grid stabilizing services, voltage support, black start, cold load pick up, conservation voltage reduction, and other reserve services.

6. The method of claim 1, wherein the measurement and verification data is associated with individual power consuming devices.

7. The method of claim 1, further including aggregating the measurement and verification data for a multiplicity of power consuming devices.

8. The method of claim 1, further comprising communicating a status message to the load management server, the status message indicating a status of the at least one controllable device.

9. The method of claim 1, further comprising communicating a status message to the load management server, the status message indicating a total amount of power consumed by the at least one associated power consuming device and the corresponding measurement and verification data.

10. The method of claim 1, further comprising receiving a subsequent power control message from the load management server instructing the client device to enable the electric power flow to the at least one associated power consuming device with the electric power flow previously disabled.

11. The method of claim 1, further comprising:

the client device receiving a status message from the load management server, the status message requesting status information for the at least one controllable device;

the client device receiving a status response message from the at least one controllable device; and

storing each status response message in a memory for reference in connection with power reduction events.

12. The method of claim 1, wherein at least one Internet-accessible device is coupled to the client device, wherein the client device includes a Layer-3 router operable for:

receiving an Internet Protocol (IP) message that includes an IP address;

determining whether the IP message is directed to the Internet-accessible device coupled to the client device; and

communicating the IP message to the Internet-accessible device.

13. The method of claim 1, wherein the power control message includes a list of controllable devices to be instructed to disable the electric power flow to associated power consuming devices, and wherein the power management command causes the controllable devices identified in the list to disable the electric power flow to the associated power consuming devices to achieve the reduction in consumed power.

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

a client device comprising at least one controllable device interface facilitating communication of power control instructions to at least one controllable device, the power control instructions operable to cause the at least one controllable device to selectively enable and disable a flow of electric power to at least one power consuming device; and

a device control manager operably coupled to the at least one controllable device interface, the device control manager operable to issue power control instructions to the at least one controllable device through the at least one controllable device interface responsive to the received power control instructions, and based upon a reduction in consumed power for disabled flow of electric power, generate measurement and verification data corresponding to the reduction in consumed power;

wherein the client device receives a power control message from a remote load management server, and wherein the power control message received from the remote load management server is responsive to a power reduction request.

15. The system of claim 14, wherein a power supply value (PSV) is generated corresponding to the reduction in consumed power, and wherein the PSV indicates a compensation provided for power supply associated with the reduction in consumed power.

16. The system of claim 15, wherein the compensation includes at least one of capacity compensation, energy compensation, operating reserves compensation, compensation to include ancillary services, other grid stabilizing services, voltage support, black start, cold load pick up, conservation voltage reduction, and other reserve services.

17. The system of claim 15, wherein the PSV is generated based upon a governing entity for the power grid operating region and/or operational regulations.

18. The system of claim 14, wherein the power control message indicates at least one of an amount of electric power to be reduced and an identification of a controllable device to be instructed to disable the flow of electric power to the at least one power consuming device.

19. The system of claim 14, further comprising a communications interface facilitating communications between the remote load management server and the client device, wherein the device control manager communicates at least one power consumption indicator and at least one power management status to the remote load management server via the communications interface.
