The successful integration of battery energy storage systems (BESSs) is crucial for enhancing the resilience and performance of microgrids (MGs) and power systems. This study
Simulation validation shows that, compared to the traditional uniform power control strategy, the proposed control strategy can effectively balance the SOH and SOC states of
To improve the carrying capacity of the distributed energy storage system, fast state of charge (SOC) balancing control strategies based on reference voltage scheduling (RVSF)
State of charge (SOC) balancing is significant for high voltage transformerless (HVT) battery energy storage system (BESS) to utilize their full energy capacity. However, traditional

proposed a local-distributed and global-decentralized SOC balancing control strategy for hybrid series-parallel energy storage systems, which can offset the SOC of each energy storage unit (ESU) to the same value in a distributed manner. This paper also analyzes the stability of small-signal modeling, which guides parameter design.
SOC balancing for capacity inconsistent systems In a system consists of ESUs with inconsistent capacities, the storage units' target energy no longer equals the average value.
More specifically, it shows that the maximum-SOC unit (i.e., unit 1) keeps a maximum discharging power during most of the SOC balancing process. At the end of the SOC balancing process, the minimum-SOC unit (i.e., unit 3) keeps a maximum charging power for a short time.
Compared with the traditional control strategy, the proposed control strategy can effectively balance the SOH and SOC of each energy storage unit and keeps the system's overall capacity for a longer period.
