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 on an electric power grid comprising:

a server having a processor coupled with a memory, and constructed and configured for communication over a network for communicating Internet Protocol (IP)-based messages with power consuming devices and power supplying devices for generating operating reserves;

wherein the IP-based message includes information relating to activities by the power consuming devices and the power supplying devices comprising power consumed by the power consuming devices and power supplied by the power supplying devices and an amount of power available to be reduced to each of the power consuming devices and an amount of power available to be supplied by each of the power supplying devices;

a database for storing the information relating to the activities by the power consuming devices and the power supplying devices;

wherein the information is transformed by the system into settlement grade data corresponding to the activities of the power consuming devices and the power supplying devices;

wherein the amount of power available to be reduced to the power consuming devices is transformed into a supply equivalent value accepted by a governing entity;

wherein the settlement grade data includes a quantification of revenue grade power available to be reduced or curtailed by the activities of the power consuming devices and revenue grade power available to be supplied by the activities of the power supplying devices;

wherein the settlement grade data further includes information from any revenue grade meter or sub-meter capable of calculating and reporting revenue grade or acceptable metrology within a time interval; and

wherein the settlement grade data is used for making financial settlement for load curtailment as a supply to a power market by the power consuming devices and energy supply to the power market by the power supplying devices.

2. 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.

3. The system of claim 1, wherein the revenue grade metrology is included in one or more memory registers accepted by a Grid Operator, Independent System Operator (ISO), Governing Agency or Standards Bodies.

4. 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.

5. 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 the memory.

6. The system of claim 1, wherein the information includes at least one of grid reliability information, grid stability information, and operating reserves information.

7. The system of claim 1, wherein the IP-based messages include information relating to at least one of a change in state of the power consuming device(s) and/or power supplying device(s), 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.

8. 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 the power consuming devices and/or the power supplying devices.

9. The system of claim 1, wherein the reporting of revenue grade data can be interval based and or autonomously stored and reported at a future time.

10. The system of claim 1, wherein information stored in the database further includes a status of the power consuming devices and/or the power supplying devices.

11. The system of claim 1, wherein at least one of the IP-based messages includes power control commands requiring a reduction in an amount of electric power consumed by the power consuming device(s) to instruct the supply of electric power by the power supply device(s) to the same net effect on the electric power grid.

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

13. The system of claim 12, wherein the at least one smart meter includes an internal gateway.

14. The system of claim 12, wherein the at least one smart meter is coupled with an external gateway.

15. The system of claim 12, 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 one another and/or the controllable device(s).

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

19. The system of claim 18, wherein the coordinator further provides 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 power control commands are aggregated to a minimum capacity amount required for settlement grade data.

23. The system of claim 1, wherein the IP-based messages include at least one power consumption indicator and at least one power management status that are included in the settlement grade data.

24. The system of claim 1, further including customer profiles associated with the power consuming devices and/or power supplying devices.

26. The system of claim 1, wherein the power consuming devices and/or power supply devices include any grid element that is single phase or multiphase.

27. The system of claim 1, wherein the messages are supplied to a predictive algorithm for providing a market participant load or supply information for predicting availability of load or supply for curtailment in the future.
