Abstract

Systems, methods, and apparatus embodiments for electric power grid and network registration and management of grid elements. Grid elements are transformed into 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 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. An apparatus for electric power grid management and communication, comprising:

wherein the apparatus is operable for communicating at least one Internet Protocol (IP)-based message with the at least one grid element in an electric power grid;

wherein the at least one IP-based message comprises an initial message from the at least one grid element to the apparatus for registration;

wherein the initial message includes a unique grid element identifier, an equipment identifier, a class of service information, capability, capacity, function information, geodetic information, an attachment point of the electric power grid, IP address information, communication format, content information, security information, and authentication information;

wherein the at least one IP-based message includes at least one IP packet that is generated autonomously and/or automatically by at least one grid element and/or the apparatus by transforming a raw data into a transformed content,

wherein the raw data corresponds to at least one attribute of the at least one grid element and/or the apparatus;

wherein the at least one attribute includes calibration, the capacity, security, settlement, status, table information, pricing, telemetry, changes in time, location of market, attachment point information, the geodetic information, the unique grid element identifier, at least one grid element profile, power consumption, power flows, information accuracy of the at least one grid element, software, firmware, upgrades, and/or prioritization;

wherein the at least one IP-based message includes a priority; and

wherein the at least one IP-based message is sent in real time or within 15 minutes after the transformation of the raw data into the transformed content.

2. The apparatus of claim 1, wherein the apparatus is further operable for communicating over an electric power grid network with at least one coordinator operable for routing the at least one IP-based message, wherein the at least one coordinator is further operable to:

inspect the at least one IP-based message, including the priority, a composition, a payload, and/or a presentation; and

route the at least one IP-based message automatically and/or intelligently responsive to the priority, composition, payload, and/or presentation.

3. The apparatus of claim 1 wherein the priority includes at least one of a standard time-based priority, a function-based priority, a normal priority, an increased priority with respect to the normal priority, a top level priority, a market-based priority, a static priority, and a dynamic priority.

4. The apparatus of claim 3 wherein the at least one IP-based message relates to at least one of a stability of the electric power grid and an outage reporting, wherein the priority includes the top level priority.

5. The apparatus of claim 3 wherein the at least one IP-based message relates to a reliability of the electric power grid, wherein the priority includes the increased priority with respect to the normal priority.

6. The apparatus of claim 3 wherein the at least one IP-based message relates to a market price of energy, wherein the priority includes the increased priority with respect to the normal priority.

7. The apparatus of claim 3 wherein the at least one IP-based message relates to a general grid communication, wherein the priority includes the normal priority.

8. The apparatus of claim 1 wherein the priority is chosen from at least two levels of priority, wherein at least one level of priority is based upon needs of the electric power grid during a given time period.

9. The apparatus of claim 1 wherein the priority depends upon a governing authority or an entity of the grid, a market price or a unit being removed from a service line, a transmission line, a location marginal price (LMP), a need for auto-dispatch control, a load generation, and/or a curtailment.

10. The apparatus of claim 1, wherein the priority is automatically generated by the at least one grid element and/or the apparatus, wherein the priority is based on the raw data and/or the transformed content.
