Battery energy storage system has the potential ability of regulating active and reactive power rapidly and independently.It has great application value in load-leveling,uninterruptable power supply,power quality conditioning,etc.A 100 kW/150 kVA power conversion system for 100 kW battery energy storage module was designed with its main circuit,component parameters and control system.The design was aiming at storage systems with the capacity up to MWs.In the power conversion system,the DC/AC's instantaneous current controller was applied to track the three-phase reference currents separatively in different grid voltage circumstances,and the boost bidirectional DC/DC circuit between batteries and DC bus was controlled by double-loops feedback to regulate battery currents.On that basis,two coordinate control schemes were proposed.Simulations and experimental tests verify the stability and anticipant response of the control system designed above.
