Power Grid Photo-voltaic Integration using Distributed Energy Storage and Management

摘要

Distributed energy storage within the distribution network of an electric power network at least partially supplied by time varying and unpredictable generation sources provides smoothing of energy flow within the distribution network. The distributed energy storage may include a plurality of distributed energy storage units operating under the control of a single controller or regional controllers. The distributed energy storage units may operate as groups of units or as separate units.

主权项

1. A method of integrating a plurality of renewable energy sources, the renewable energy source characterized by varying or unpredictable output with time, the method comprising:
providing a plurality of distributed energy storage units and coupling each of the distributed energy storage units to one or more of the renewable energy sources; providing a controller and communicatively coupling the controller to each of the plurality of distributed energy storage units and to each of the renewable energy sources; and directing from the controller one or more of the distributed energy storage units to one of store energy from a coupled renewable energy source and dispatch energy from its storage to a distribution feeder.
