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 power consuming device and at least one power supplying device;

wherein the IP-based messages comprise an amount of power consumed and an amount of power available to be reduced by the at least one power consuming device and an amount of power supplied and an amount of power available to be supplied by the at least one power supplying device;

a database for storing information including revenue grade metrology data from at least one revenue grade meter or sub-meter within a time interval relating to activities of the at least one power consuming device and the at least one power supplying device;

wherein the amount of power available to be reduced to the at least one power consuming device is transformed into a supply equivalency value accepted by a governing entity based on measurement and verification, wherein the supply equivalency value provides for a curtailment value as a requirement for providing supply to the electric power grid;

wherein the server initiates power control instructions causing the at least one power consuming device to reduce consumed power based on the information stored in the database and the supply equivalency value;

wherein the operating reserves are generated based on the supply equivalency value from the at least one power consuming device and the amount of power available to be supplied by the at least one power supplying device.

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

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

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

5. The system of claim 1, wherein the information stored in the database further includes at least one of:

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

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

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

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

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

10. The system of claim 1, wherein the server comprises a meter data management software operable for interpolating interval data from the at least one revenue grade meter or sub-meter.

11. The system of claim 7, wherein the power control commands include instructions for managing power control events and corresponding reduction in power to predetermined devices.

12. The system of claim 1, further comprising at least one of an event manager, a client device manager, and a device control manager that is operably coupled with the at least one power consuming device and the at least one power supplying device.

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

14. The system of claim 13, wherein the coordinator is operable to provide persistence or caching of the IP-based messages.

15. The system of claim 1, wherein the revenue grade metrology data is communicated in real-time, near real-time, or a timing required by a grid operator entity for generating operating reserves for grid stability.

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

17. The system of claim 1, wherein the supply equivalency value is aggregated to a minimum capacity amount.

18. The system of claim 1, wherein the server is further operable to generate customer profiles associated with the at least one power consuming device and the at least one power supplying device and aggregate the customer profiles into a plurality of groups based on at least one predetermined criterion.

19. The system of claim 18, wherein the database is further operable to store the customer profiles associated with the at least one power consuming device and the at least one power supplying device.

20. The system of claim 18, wherein each of the customer profiles comprises a customer name, a customer address, a geodetic location, a meter ID, at least one customer program, device information, customer energy consumption patterns, and a connection and disconnection profile.
