An Improved Droop Control for Balancing State of Charge of Battery Energy Storage Systems in AC Microgrid
In order to avoid overuse of a certain battery energy storage system (BESS) and prolong the cycle life of battery in AC microgrid, an improved SoC-based droop control based on multi-agent system (MAS) is proposed for achieving State of Charge (SoC) balance of multiple BESS units.A proportional-integral (PI) adjustment item using the average SoC is
