摘要：For the grid connected by high proportion distributed power, energy storage system can effectively reduce the adverse impact of micro grid power fluctuation on the grid. Because of the high cost of energy storage system, it is necessary to optimize the capacity of energy storage system. Therefore, this paper proposes a capacity optimization method of energy storage system. Based on the comprehensive consideration of system objectives, construction costs, energy storage security and other factors, the simulation analysis model of the system is established, and the control strategy is optimized. In this paper, the algorithm is applied to the construction of microgrid demonstration project. The experimental results verify the effectiveness of the proposed method.
