摘　　要：结合液流电池储能电站架构和控制方式,对基于DC总线并联电池模块功率分配技术展开研究,提出了一种多储能模块的双层功率分配策略,实现直流侧多个液流电池储能模块的SOC快速动态均衡。结合实际算例,通过对比功率均分、分级投切策略,验证所提策略有效性。Combined with the flow battery energy storage power station architecture and control method,the power distribution technology based on the DC bus parallel battery module is researched,and a double-layer power distribution strategy of multiple energy storage modules is proposed to achieve multiple flow battery storage on the DC side.The SOC of the module can be quickly and dynamically balanced.Combined with actual calculation examples,the effectiveness of the strategy is verified by comparing the power sharing and hierarchical switching strategies.
