摘要：
Aiming at the inconsistency of the state of health (SOH) and the state of charge (SOC) of energy storage units caused by irregular charging and discharging of a large battery energy storage system (BESS) composed of multiple energy storage units, the relationship between SOH difference in energy storage units and SOC consistency is studied. Combining the prioritization of charging and discharging and adaptive mutation particle swarm optimization (AMPSO) algorithm, a BESS power allocation strategy considering the consistency of SOH and SOC of energy storage units is proposed. Based on the measured data of the grid-connected demonstration platform of centralized microgrid with common DC-bus including the BESS, wind/photovoltaic power generation, electric vehicle and conventional loads, the proposed power distribution control strategy is compared with the traditional distribution control strategies. The simulation results show that the proposed control strategy can effectively improve the SOC consistency, prolong the service life and reduce the operation loss of the energy storage unit, as well as enhance the bidirectional regulation capability of the BESS. © 2023 Automation of Electric Power Systems Press.
