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 electric power grid element and network management, comprising:

at least one grid element constructed and configured for Internet Protocol (IP)-based network communication with a server and at least one database via at least one coordinator;

wherein the at least one grid element communicates an initial message to the at least one coordinator for registration with an electric power grid;

wherein the at least one coordinator is operable to register and introduce the at least one grid element to the electric power grid;

wherein the at least one grid element is automatically and/or autonomously transformed into at least one active grid element via registration with the electric power grid;

wherein the at least one active grid element is operable to send messages to and receive messages from the server via the at least one coordinator;

wherein the at least one coordinator is operable to route messages from the at least one active grid element to the at least one database; and

wherein the server exchanges with the at least one database information associated with the at least one active grid element for affecting electric grid operations, reporting, and/or stabilization.

2. The system of claim 1, wherein the at least one coordinator is operable to manage the at least one active grid element according to their characteristics, profiles, location and capability for responsiveness to various electric power grid resource requirements.

3. The system of claim 1, wherein the at least one coordinator is operable to match and prioritize the at least one active grid element for managed participation within the electric power grid.

4. The system of claim 1, wherein the at least one grid element is a device that consumes electric power from the electric power grid, supplies power to the electric power grid, and/or measures power relating to the electric power grid.

5. The system of claim 1, wherein at least one of the at least one grid element is a control device that operates, programs, and/or updates the other active grid elements.

6. The system of claim 1, wherein each of the at least one grid element has a unique grid element identifier.

7. The system of claim 1, wherein the initial message includes at least one of:

status of device, supply source, and/or demand;

location of attachment;

line losses;

distribution and transmission capacity information;

grid stability information; and

combinations thereof.

8. The system of claim 1, wherein the initial message further includes at least one of:

a geodetic reference, a grid element identifier, a grid element authentication, a grid element type, a grid element function, a grid element capacity, 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, a grid element compatibility identifier, and combinations thereof.

9. The system of claim 1, wherein the initial message has a deliver priority including at least one of a plurality of methods to include priority access flags, virtual private networks, independent identifying addresses, manufacturers specific identifying codes, or combinations thereof.

10. The system of claim 1, wherein the registration complies with regulations and/or standards established by Federal Energy Regulatory Commission (FERC), North American Electric Reliability Corp. (NERC), Independent System Operator (ISO), and/or a governing authority for the electric power grid.

11. The system of claim 1, wherein the at least one active grid element is operable to provide operating reserves and/or grid stabilization, and/or to serve native load, for the electric power grid.

12. The system of claim 1, wherein information relating to the registration and transformation of the at least one grid element is stored in the at least one database for predetermined periods of time for use with settlement associated with the at least one active grid element.

13. The system of claim 1, further comprising a security interface associated with each of the at least one grid element provides protection for the contents of the messages exchanged between the at least one active grid element, the at least one coordinator, the at least one database and the server.

14. The system of claim 13, wherein the security interface is standards-based or determined by a governing entity that regulates grid operations for utilities, market participants or grid operators.

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

at least one grid element communicating an initial message to at least one coordinator for registration with an electric power grid;

the at least one coordinator registering and introducing the at least one grid element to the electric power grid;

the at least one grid element automatically transforming into corresponding at least one active grid element for functioning actively within the electric power grid after registration with the electric power grid;

the at least one active grid element sending messages to and receiving messages from the server routed by the at least one coordinator;

the at least one coordinator routing messages from the at least one active grid element to at least one database; and

the server exchanging with the at least one database information associated with the at least one active grid element for affecting electric grid operations, reporting, and/or stabilization.

16. The method of claim 15, further comprising storing information relating to the registration and transformation of the at least one grid element in the at least one database for predetermined periods of time for use with settlement associated with the at least one active grid element.

17. The method of claim 15, further comprising the at least one coordinator matching and prioritizing the at least one active grid element for managed participation within the electric power grid.

18. The method of claim 15, further comprising the at least one coordinator managing the at least one active grid element according to their characteristics, profiles, location and capability for responsiveness to various electric power grid resource requirements.

19. The method of claim 15, further comprising the at least one active grid element communicating updates to the server and/or the at least one database via the at least one coordinator.

20. The method of claim 15, further comprising the at least one active grid element providing operating reserves and/or grid stabilization, and/or to serve native load, for the electric power grid.
