针对储能系统单一运行模式难以满足光储充电站多类技术需求的问题,提出一种考虑多模式融合的光储充电站储能系统优化运行策略。首先,分析光储充电站储能系统典型运行模式,在此基础上进行储能系统多模式融合设计;其次,建立不同模式下光储充电站储能系统运行模型,进一步提出多模式融合的光储充电站储能系统优化运行策略;最后,基于上海某光储充电站24 h运行曲线,对所提策略进行仿真与实验分析。结果表明:所提策略可降低光储充电站并网负荷波动和储能系统能量平衡用电成本,提升光储充电站运行效益。

A single operation mode of the energy storage system is difficult to meet various technical requirements of a photovoltaicstorage charging station.In view of this problem,this paper proposes an optimal operation strategy of the energy storage system in a photovoltaic-storage charging station considering multi-mode integration.Firstly,typical operation modes of the energy storage system in a photovoltaic-storage charging station are analyzed,and multi-mode integration of the energy storage system is designed on this basis.Secondly,operation models of the energy storage system in the photovoltaic-storage charging station under different modes are established to further propose an optimal operation strategy of the energy storage system in the photovoltaic-storage charging station with multi-mode integration.Finally,the proposed strategy is simulated and experimentally analyzed based on 24 h operation curves of a photovoltaic-storage charging station in Shanghai.The results show that the proposed strategy can reduce load fluctuation and energy-balance cost of the energy storage system,thus improving operating benefits of the photovoltaic-storage charging station.
