Abstract

Abstract:

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.

Key words: flow battery, integrated technology, SOC balance, system configuration, power distribution, switching strategy
