Abstract

Systems and methods for managing power on an electric power grid including a server for communicating IP-based messages over a network with distributed power consuming devices and/or power supplying devices, the IP-based messages including information relating to activities by the power consuming devices and/or the power supplying devices; and wherein the information is transformed by the system into settlement grade data corresponding to the activities of the power consuming devices and/or the power supplying devices.

Claims

1. A system for managing power information for generating operating reserves on an electric power grid comprising:

a server constructed and configured for communication over a network for communicating Internet Protocol (IP)-based messages with at least one device for consuming or supplying electric power;

wherein the IP-based messages include information relating to activities of the at least one device for consuming or supplying electric power, the information comprising an amount of power consumed or supplied and an amount of power available to be reduced or supplied by the at least one device for consuming or supplying electric power;

a database for storing the information relating to the activities by the at least one device for consuming or supplying electric power;

wherein the information is transformed by the system into settlement grade data corresponding to the activities of the at least one device for consuming or supplying electric power;

wherein the settlement grade data includes a quantification of revenue grade power available to be reduced or curtailed or to be supplied by the activities of the at least one device for consuming or supplying electric power; and

wherein the settlement grade data further includes information from any revenue grade meter or sub-meter capable of communicating revenue grade or acceptable metrology within a time interval.

2. The system of claim 1, wherein the IP-based messages are prioritized based upon function and participation of the at least one device for consuming or supplying power.

3. The system of claim 1, wherein the IP-based messages are processed by the server based upon the function and participation of the at least one device for consuming or supplying power.

4. The system of claim 1, wherein the IP-based messages are queued, prioritized, transformed, and/or aggregated based upon the function and participation of the at least one device for consuming or supplying power.

5. The system of claim 1, wherein the time interval is a specified time interval as required by the Independent System Operator (ISO), Utility, Grid Operator or government entity governing market settlement operations.

6. The system of claim 1, wherein the revenue grade metrology is reported or stored by at least one of a smart meter, sub-meter, and meter device.

7. The system of claim 1, wherein the revenue grade metrology is included in an Interval Data Recorder (IDR) register or in interval data stored in memory for the at least one device.

8. The system of claim 1, wherein the information includes at least one of:

grid reliability information, grid stability information, and operating reserves information.

9. The system of claim 1, wherein the IP-based messages include information relating to at least one of a change in state of the at least one power consuming device and/or at least one power supplying device, a directive for a change in state of the power consuming device(s) or power supplying device(s), a priority message, an alert, a status, an update, a location with respect to the electric power grid, a function, device attributes, and unique identifier.

10. The system of claim 1, wherein the server is operable to receive or initiate power control commands and corresponding IP-based messages in communication with of the at least one device for consuming or supplying power.

11. The system of claim 1, wherein the reporting of revenue grade data is interval-based.

12. The system of claim 1, wherein information stored in the database further includes a status of the at least one device for consuming or supplying power.

13. The system of claim 1, wherein at least one of the IP-based messages include power control commands requiring a change in power consumed or supplied by the at least one device for consuming or supplying power.

14. The system of claim 1, further including at least one smart meter in network-based or IP-based communication with the server.

15. The system of claim 1, further including meter data management software operable on the server for interpolating interval data from the at least one smart meter or at least one revenue grade sub-meter.

16. The system of claim 1, wherein the power control commands include instructions for managing power control events and corresponding reduction in power to predetermined devices.

17. The system of claim 1, further including at least one of an event manager, a client device manager, a device control manager, and a coordinator that is operably coupled with at least one of the controllable devices.

18. The system of claim 1, further including a coordinator for routing the IP-based messages between the server and the at least one device for consuming or supplying power.

19. The system of claim 1, further including a coordinator that is operable to provide persistence or cache of the IP-based messages.

20. The system of claim 1, wherein the system is operable for providing revenue grade metrology for real-time, near real-time, or the timing required by the grid operator entity for generating operating reserves for grid stability.

21. The system of claim 1, wherein the server is responsive to messages from an EMS or a grid operator to provide stability and/or reliability for the electric grid, wherein the messages are provided under one or more protocols that are standards-based or proprietary-based protocols, so that the grid element is responsive to at least one of an operational grid subsystem, an Energy Management System (EMS), a sub-EMS, and a coordinator.

22. The system of claim 1, wherein the settlement grade data is aggregated to a minimum capacity amount.

23. The system of claim 1, further including customer profiles associated with the at least one device for consuming or supplying power.

24. The system of claim 1, wherein the power control messages for the at least one device for consuming or supplying power provide for current or projected future requirements of the electric power grid.
