Abstract

In islanded microgrids,the traditional wireless active power coordinated control may lead to the state of charge (SOC)of the battery energy storage system (BESS)getting beyond the safe operation region if imbalance between power consumption and generation lasts too long.To address this issue,a distributed active power coordinated control strategy for multiple BESS and renewable energy source(RES)units considering SOC of BESS is proposed.By integrating variable-slope
droop control based on instantaneous power,constant-power proportional-integral(PI)droop control based on SOC,and power droop control based on frequency bus signaling (FBS),an autonomous wireless coordinated control for active power is achieved.In addition,not only can the strategy proposed be easily implemented on top of the conventional BESS and RES control systems without altering the inner loop structure,but also it can keep the SOC in a safe range when efficiently utilizing the power from RES.Real-time simulation results validate the effectiveness of the control strategy proposed.
