Multi-objective Capacity Optimal Configuration of Photovoltaic Microgrid Energy Storage System
The energy storage is an important measure to solve renewable energy consumption and improve system operation re-liability.To solve the problem,a multi-objective capacity optimal configuration of photovoltaic microgrid energy storage system based on time-sharing energy complementarity is proposed.According to the structure of photovoltaic microgrid energy storage system,its working principle is analyzed to provide theoretical support for capacity optimization.A multi-objective capacity op-timization model is constructed from the three objectives of reducing life cycle cost,restraining renewable energy power fluctua-tion and maximizing tie line utilization.Based on the time-sharing energy complementary technology,an optimization algorithm with complementary characteristics is designed.Through the multi-objective solution,the best scheme is obtained for the multi-objective capacity optimal configuration.The experimental results show that the proposed method improves the utilization of the interconnection line of the microgrid,effectively suppresses the power fluctuation of the system,and improves the compre-hensive income of the system.
