Scheduling and control in a power aggregation system for distributed electric resources
First Claim
1. A method, comprising:
- inputting constraints of individual electric resources into a power aggregation system, wherein the power aggregation system signals the electric resources to provide power to or take power from a power grid;
scheduling power aggregation based on the constraints;
classifying the electric resources on lists, the lists including;
a first dynamically prioritized list of electric resources that can be activated for storing power from the power grid and providing a load for the power grid; and
a second dynamically prioritized list of electric resources that can be activated for discharging and providing power to the power grid;
assigning a cost to each resource on the first dynamically prioritized list and the second dynamically prioritized list, wherein a priority order of the lists is directly related to the costs;
wherein assigning a cost includes determining a cost function, the cost function guided by predicting a total system availability;
building a set of models, wherein each model is used to predict a behavior of multiple electric resources;
grouping similar electric resources for creating the models and for assigning the electric resources to each model; and
wherein the assigning includes identifying features of each electric resource, including at least one of a number of unique connections/disconnections per day, typical connection times, average connection duration, and an average state-of-charge at connection time.

Abstract
Systems and methods are described for a power aggregation system. In one implementation, a service establishes individual Internet connections to numerous electric resources intermittently connected to the power grid, such as electric vehicles. The Internet connection may be made over the same wire that connects the resource to the power grid. The service optimizes power flows to suit the needs of each resource and each resource owner, while aggregating flows across numerous resources to suit the needs of the power grid. The service can bring vast numbers of electric vehicle batteries online as a new, dynamically aggregated power resource for the power grid. Electric vehicle owners can participate in an electricity trading economy regardless of where they plug into the power grid.
