Abstract

A utility employs a method for generating available operating reserve. Electric power consumption by at least one device serviced by the utility is determined during at least one period of time to produce power consumption data, stored in a repository. A determination is made that a control event is to occur during which power is to be reduced to one or more devices. Prior to the control event and under an assumption that it is not to occur, power consumption behavior expected of the device(s) is generated for a time period during which the control event is expected to occur based on the stored power consumption data. Additionally, prior to the control event, projected energy savings resulting from the control event, and associated with a power supply value (PSV) are determined based on the devices'"'"' power consumption behavior. An amount of available operating reserve is determined based on the projected energy savings.

Claims

1. A method for supplying operating reserve for an electric power grid comprising the steps of:

determining amounts of electric power stored by devices located at one or more service points to produce stored power data and corresponding revenue grade metrology for the amounts of electric power stored by the devices;

storing the stored power data in a repository;

determining an amount of available operating reserve based on at least the stored power data;

receiving a request for operating reserve from a utility and/or a market participant of the electric power grid; and

responsive to the request for operating reserve, managing a flow of electric power from the devices to the electric power grid to provide the operating reserve.

2. The method of claim 1, wherein receiving the request for operating reserve comprises:

receiving one of an Automatic Generation Control command and an independent service operator market signal.

3. The method of claim 1, further including the step of providing an acknowledgement message following the step of receiving the request for operating reserve.

4. The method of claim 1, wherein the devices include at least one of electric vehicles and hybrid electric vehicles.

5. The method of claim 1, further including the step of generating a power supply value (PSV) for the amounts of electric power stored by the devices.

6. The method of claim 5, wherein the PSV provides a monetary market value for equating as a corresponding power supply for the amounts of electric power stored by devices.

7. The method of claim 5, wherein a commercial value for the devices is determined based on the PSV associated with the devices.

8. A method for supplying operating reserves for at least one grid operator via a control device on an electric power grid comprising the steps of:

determining an amount of electric power stored by at least one device at a service point and corresponding revenue grade metrology for the at least one device;

reporting the amount of stored power to a controller; and

controlling a flow of electric power from the at least one device to a power grid accessible by the at least one grid operator responsive to a request from the controller for operating reserves by the at least one grid operator.

9. The method of claim 8, wherein the step of reporting the amount of stored power to the controller is performed by a control device located at the service point on the electric power grid.

10. The method of claim 8, wherein the at least one device includes an electric vehicle.

11. The method of claim 9, wherein the control device is integrated into a charging station for an electric vehicle.

12. The method of claim 8, further comprising the steps of:

determining that at least one other device is in process of being charged from the at least one grid operator, a market participant, or an independent operator of one or more charging stations;

receiving a message from the controller to commence a control event at the service point; and

ceasing charging of the at least one other device responsive to the message.

13. The method of claim 12, wherein the one or more charging stations are controlled in the aggregate and presented to a market for electric power or to a utility.

14. The method of claim 8, wherein the controller is a central controller.

15. The method of claim 8, further including generating a power supply value (PSV) for the amount of electric power stored by the at least one device.

16. The method of claim 15, wherein the PSV provides a monetary market value for equating as a corresponding power supply for the amount of electric power stored.

17. The method of claim 15, wherein a commercial value for the stored power is determined based on the PSV associated with the at least one device.

18. A method for providing operating reserves for at least one grid operator of an electric power grid comprising the steps of:

receiving a request for operating reserve from the at least one grid operator of the electric power grid;

determining and aggregating amounts of electric power stored by devices associated with at least one service point on the electric power grid;

generating stored power data and corresponding revenue grade metrology for the amounts of electric power stored by the devices available as operating reserves; and

managing a flow of electric power from the devices, via a control device associated with one of the devices, to the electric power grid to provide the operating reserve.

19. The method of claim 18, further including generating a power supply value (PSV) for the amounts of electric power stored by the devices.

20. The method of claim 19, wherein the PSV provides a monetary market value for equating as a corresponding power supply for the amounts of electric power stored.
