Abstract

Aiming at the problem of state of health （SOH） imbalance of distributed energy storage system（DESS） in islanded AC microgrid when adopting conventional P-f droop control, a SOH balance scheme based on multi-agent is proposed. Through the information interaction of depth of discharge （DOD） among DESS agents, the SOH balance of DESS is realized. The service life of DESS is prolonged and the maintenance cost of microgrid is reduced by adjusting the active power output of DESS according to the SOH state of DESS. Finally, the PSCAD simulation software and the experimental platform are used for simulation and experimental verification, which indicates that the proposed scheme is effective.
