In micro grid, the distributed generations have a large proportion and the energy storage system is the fundamental structure of the micro grid. Wind and photovoltaic power generation contain intermittent and uncertain characteristics. Energy storage system in micro grid can smooth the volatility of distributed power and supply power to important loads in case of the insufficiency of distributed power generation. In this paper, a location and capacity planning method of energy storage system is proposed. The energy storage installation points are the key points of the system, which are identified based on the electrical distance. Further, the capacity is optimized and solved on these basics. Finally, the effectiveness of the proposed method is verified through case studies.
