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 at least one 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 at least one server via the at least one coordinator;

wherein the at least one server is operable to communicate IP-based messages to each of the at least one active grid element through the at least one coordinator after the registration;

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;

wherein the at least one server is configured to operate the at least one database to exchange information associated with the at least one active grid element for affecting electric grid operations, reporting, and/or stabilization;

wherein the registration 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; and

wherein the at least one coordinator is operable to provide an assessment of electric grid operations comprising energy flows within the electric power grid, grid stabilization, operating reserves, capacity, and settlement.

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 its 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 8, wherein the PSV is a supply equivalence value based on measurement and verification of reduction in power consumption and the PSV is accepted and awarded by a governing entity.

10. The system of claim 1, wherein the initial message has a delivery 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.

11. 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.
