Abstract: In this paper, a strategy for the control and integration of battery energy storage system (BESS) for the more electric aircraft (MEA) electrical power system (EPS) application is proposed. The MEA DC EPS considering a single source and a battery storage system in the MEA is studied in this paper. The BESS is integrated into the MEA EPS distribution network DC bus (270 V) using the bidirectional DC-DC converter. The battery and the PMSG are linked to the same DC bus through a DC-DC converter and an AC/DC converter, respectively. The BESS can be used to power some onboard loads during an emergency, and to provide or absorb power when there is load variation. Therefore, the control of the BDC with fast dynamic response is required. Consequently, a strategy for the fast response control of the inductor current is implemented.
