Abstract

Systems, methods, and apparatus embodiments for electric power grid and network registration and management of active grid elements. Grid elements are transformed into active grid elements following initial registration of each grid element with the system, preferably through network-based communication between the grid elements and a coordinator, either in coordination with or outside of an IP-based communications network router. A multiplicity of active grid elements function in the grid for supply capacity, supply and/or load curtailment as supply or capacity. Also preferably, messaging is managed through a network by a Coordinator using IP messaging for communication with the grid elements, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

Claims

1. A system for network registration and management of grid elements in an electric power grid, comprising:

at least one grid element in network-based communication with a server associated with the electric power grid;

wherein the at least one grid element communicates an initial message including a priority of delivery to the server and is registered with the electric power grid based on the initial message;

wherein the initial message includes a class of service information and function information;

wherein the at least one grid element is correspondingly transformed into at least one active grid element via the registration with the electric power grid; and

wherein the at least one active grid element is operable to actively function within the electric power grid based on the class of service information and the function information of the initial message.

2. The system of claim 1, wherein the initial message further includes:

a geodetic reference, a grid element type, a grid element profile, a grid element attachment point reference, a grid element power supply value (PSV), a grid element power trade block (PTB) value, a grid element balancing authority association, a grid element owner identifier, and/or a grid element compatibility identifier.

3. The system of claim 1, wherein the at least one active grid element provides power supply, curtailment as power supply, operating reserves, and/or other reserves to the electric power grid.

4. The system of claim 1, further comprising at least one coordinator in network-based communication with the at least one active grid element and the server.

5. The system of claim 4, wherein the at least one coordinator is operable to register the at least one grid element.

6. The system of claim 4, wherein the at least one coordinator is operable to match and prioritize the at least one active grid element.

7. The system of claim 1, wherein the network-based communication is IP-based messaging.

8. The system of claim 1, wherein the transformation is registered in a database and the database is registered with an Independent System Operator (ISO), balancing authority (BA), North American Electric Reliability Corp. (NERC), utility service area, and/or Federal Energy Regulatory Commission (FERC).

9. The system of claim 1, wherein registration of grid elements with the electric power grid is stored in a database for predetermined periods of time for use of settlement associated with the at least one active grid element.

10. The system of claim 1, wherein the server is operable to update at least one attribute of the at least one active grid element.

11. The system of claim 10, wherein the at least one attribute comprises a grid element power supply value (PSV) and/or a grid element power trade block (PTB) value.

12. The system of claim 1, wherein the at least one active grid element is operable to receive messages with the server via network-based communication after the registration with the electric power grid.

13. A system for network registration and management of grid elements in an electric power grid, comprising:

at least one grid element in network-based communication with a server associated with the electric power grid and at least one coordinator associated with the electric power grid;

wherein the at least one grid element communicates an initial message including a priority of delivery to the server and is registered with the electric power grid based on the initial message;

wherein the initial message includes a class of service information and function information;

wherein the at least one grid element is correspondingly transformed into at least one active grid element via the registration with the electric power grid;

wherein the at least one active grid element is operable to actively function within the electric power grid based on the class of service information and the function information of the initial message; and

wherein the at least one coordinator is operable to match and prioritize the at least one active grid element.

14. A method for electric power grid network management, comprising:

providing at least one grid element configured for network-based communication with a server;

the at least one grid element communicating an initial message including a priority of delivery to the server and becoming registered within the electric power grid based on the initial message, wherein the initial message includes a class of service information and function information; and

the at least one grid element correspondingly transforming into at least one active grid element via the registration and functioning actively within the electric power grid based on the class of service information and the function information of the initial message.

15. The method of claim 14, further comprising the server updating at least one attribute of the at least one active grid element.

16. The method of claim 14, further comprising the at least one active grid element receiving messages with the server via network-based communication.

17. The method of claim 16, further comprising at least one coordinator routing the messages between the at least one grid active element and the server.

18. The method of claim 16, wherein the messages comprise power event messages, which include:

status of device(s), supply source(s), and/or demand;

location of attachment;

line losses;

distribution and transmission capacity information; and

/or combinations thereof.

19. The method of claim 18, wherein the power event messages further include information about at least one Power Supply Value (PSV) or Power Trade Block (PTB) associated with the at least one active grid element.

20. The method of claim 18, wherein the power event messages are based upon inputs initiated from a market participant, a utility, or an electric grid operator.
