A new adaptive instantaneous average current sharing technique for circulating current minimization among parallel converters in a LV DC-microgrid

This paper proposes a new adaptive instantaneous average current sharing technique for load and minimizing circulating among parallel-connected converters in LV islanded DC microgrid. control is common parallel inverters AC systems, however, its use networks has not been reported the open literature. Unfortunately, conventional controller does come up with expected improvements terms of regulating voltage DC-DC converters. Therefore, technique, based on steepest descent method, proposed to achieve this goal. A mathematical model derived n-parallel controller. In addition, stability analysis closed-loop controllers carried out by studying locations poles using root locus plot. The simulation system demonstrate that shows better performance achieving very low level. Matlab/Simulink implemented verify under different operating conditions.
