Optimal Battery Capacity Configuration for Micro-grid Economic Planning

The research object refers to micro-grid which contains wind turbine (WT), Photo Voltaic (PV), storage and other micro-sources. Considering system operation modes, network restrictions and construction & operation costs, through coordinated control between battery storage and other micro-sources, the optimal battery capacity configuration scheme is proposed aiming at maximum economic benefits. The example micro-gird system has been simulated and the results verified the correctness and validity of the proposed method.
