摘要: Distributed secondary control plays an important role in dc microgrids, since it ensures system objectives, which are power sharing and dc-bus voltage stability. Previous studies have suggested using a architecture that utilizes parallel bus current compensation. However, the controllers mutual impact on each other, degrades transient performance of system. This paper reports alternative distributed controller design process, based small-signal analysis to alleviate effect compensation, improve response Experimental results confirm improved stability utilizing proposed architecture.
