Distributed State-of-Charge Balance Control with Dynamic Average Consensus for Multiple Energy Storage Systems

A distributed Dynamic Average Consensus (DAC) strategy is proposed to address the State of Charge (SoC) equalization control problem of multiple Battery Energy Storage Systems (BESS). This framework achieves the dual constraints of BESSs State of Charge (SoC) balance and total power demand, and reduces the communication frequency and computational complexity. The simulation results show that the proposed method has strong robustness under dynamic topologies, effectively improving the collaborative efficiency and stability of large-scale BESS clusters and providing new ideas for the optimized management of energy systems.
