Abstract

Systems and methods for managing power supplied over an electric power grid by an electric utility and/or other market participants to multiplicity of grid elements and devices for supply and/or load curtailment as supply, each of which having a Power Supply Value (PSV) associated with its energy consumption and/or reduction in consumption and/or supply, and wherein messaging is managed through a network by a Coordinator using IP messaging for communication with the grid elements and devices, with the energy management system (EMS), and with the utilities, market participants, and/or grid operators.

Claims

1. A system for managing power on an electric power grid, comprising:

a server constructed and configured in networked communication with a multiplicity of grid elements in the electric power grid;

wherein the multiplicity of grid elements comprises power consuming grid elements and power supplying grid elements;

wherein the server is operable to receive a power control command and issue a power control event message responsive thereto;

wherein the power control command comprises a power inquiry command requesting the server to determine an amount of power available for temporary reduction or increase from supply or adding to supply;

wherein the server comprises a database;

wherein the database is operable to store information comprising power consumed by the power consuming grid elements, power to be reduced to the power consuming grid elements, power supplied to the electric power grid, and power to be made available for supply to the electric power grid;

wherein the server is further operable to generate at least one power supply value (PSV), wherein each of the at least one PSV corresponds to an actual value of power to be reduced to each of the power consuming grid elements and power to be supplied to the electric power grid by each of the power supplying grid elements, wherein each of the at least one PSV is a monetary supply equivalent value based on measurement and verification, and wherein each of the at least one PSV provides for a curtailment value as a supply to the electric power grid;

wherein the generation of the at least one PSV is based on measurement and verification;

wherein the actual value of power is a supply equivalent value accepted by a governing entity to provide power supply to the electric power grid; and

wherein the system is operable for providing maintained or improved grid reliability and stability.

2. The system of claim 1, wherein the power control event message indicates an amount of power to be reduced and an identification of at least one grid element.

3. The system of claim 1, wherein the power control event message indicates an amount of power to be increased and an identification of at least one grid element.

4. The system of claim 1, wherein the power control event message indicates an amount of power to be supplied to the electric power grid and an identification of at least one grid element.

5. The system of claim 1, wherein the networked communication is Internet Protocol (IP)-based messaging.

6. The system of claim 1, wherein the networked communication is proprietary messaging.

7. The system of claim 1, wherein the power control command is initiated from a market participant, a utility, or an electric grid operator.

8. The system of claim 1, wherein the information stored in the database is revenue grade metrology data.

9. The system of claim 1, wherein the generation of the at least one PSV is based on baselining and sampling.

10. The system of claim 9, wherein the baselining provides a reference power usage point.

11. The system of claim 9, wherein the sampling includes real-time or near-real-time power measurement sampling, and wherein the sampling provides verification of power state and power consumption data, reactive power, power factor, start-up current, duty cycles, voltage, and consumption forecasts.

12. The system of claim 1, wherein the at least one PSV is operable to be aggregated into a minimum power trading block (PTB).

13. The system of claim 12, wherein the minimum PTB is determined by a governing body for the electric power grid for settlement of the supply of power to the electric power grid.

14. The system of claim 1, wherein each of multiplicity of the grid elements has a unique identifier for enhanced security.

15. The system of claim 14, wherein the unique identifier is a combination of at least one independent identifying address and an Internet Protocol Version 6 (IPv6) address;

and wherein the at least one independent identifying address is selected from the group consisting of Electronic Serial Number (ESN), International Manufacturer Equipment Identifier (IMEI), and Media Access Control (MAC) address.
