Patent ID: 7844370

Claim:
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.
