Abstract

Systems and methods for responding to electric power grid conditions may include identifying a portion of the electric power grid for power response, identifying at least one mobile energy resource and at least one connection site, and dispatching the mobile energy resource to a connection site.

Claims

1. A method for operating a response system for responding to electric power grid conditions, the response system having a controller and a database, the method comprising:

identifying a portion of an electric power grid for a power response;

identifying, based at least on data from a database, a plurality of mobile energy resources;

identifying, by the controller, at least one connection site;

determining, by the controller, for each of the identified plurality of mobile energy resources a proximity to the at least one connection site;

determining, using at least data for the plurality of mobile energy resources, for each of the identified plurality of mobile energy resources a dispatch capacity;

determining, by the controller, a rating for each of the identified plurality of mobile energy resources, wherein the rating is based partially on the proximity to the identified at least one connection site and partially on the dispatch capacity;

selecting, by the controller, based on the determined rating, one or more mobile energy resources from the plurality of mobile energy resources;

dispatching the selected one or more mobile energy resources to the at least one connection site such that upon (1) traveling to the at least one connection site and (2) connecting to the identified at least one connection site the selected one or more mobile energy resources feed power into or receive power from the power grid.

2. The method of claim 1, wherein the selected one or more mobile energy resources and the identified at least one connection site are proximate the portion of the electric power grid.

3. The method of claim 1, wherein the power response comprises an injection of electric power from the selected one or more mobile energy resources.

4. The method of claim 1, wherein the identified plurality of mobile energy resources are vehicles comprising an electrical energy source and the identified at least one connection site is configured to selectively receive power from the electrical energy source.

5. The method of claim 4, wherein the identified plurality of mobile energy resources are plug-in electric vehicles and the identified at least one connection site is a charging location configured for use with the plug-in electric vehicle.

6. The method of claim 5, wherein dispatching the selected one or more mobile energy resources to the connection site includes sending to the selected one or more mobile energy resources a discharge duration and driving directions to the at least one charging location.

7. The method of claim 6, wherein the dispatch capacity corresponds to an available discharge capacity for the plug-in electric vehicle, and the discharge duration is at least partially based on the available discharge capacity.

8. The method of claim 1, wherein dispatching the selected one or more mobile energy resources to the at least one connection site includes sending a request that the selected one or more mobile energy resources be connected to the identified at least one connection site, and the method further comprises providing an incentive for compliance with the request.

9. The method of claim 8, comprising imposing a penalty on at least some of the selected one or more mobile energy resources for noncompliance with the request.
