Whereas bipolar DC microgrid has several advantages over monopolar DC grid [1], [2], its disadvantages cannot be underestimated. The currents in the pole lines can become asymmetric, and the neutral conductor carries non-zero current. To eliminate the current imbalance caused by unipolar loads/generators in bipolar DC microgrids, different types of current redistributor have been proposed and implemented...
DC Microgrids (MGs) are increasingly popular in recent years to support distributed generation based power systems. This paper focuses on the improvement of the load sharing control strategy and presents a decentralized control scheme, namely improved digital average current sharing (IDACS). Compared to the conventional hierarchical droop control scheme, the IDACS shows the structural difference and...
