Abstract

Abstract: It is well known that accurate voltage regulation and current sharing are conflicting control objectives for DC microgrids. By taking electrical network into consideration, this paper analyzes the relation between voltage regulation and current sharing. Based on this relationship, a novel control scheme, which simultaneously considers both voltage regulation and current distribution, is proposed. It significantly simplifies the design complexity and is able to adjust the degree of compromise between accurate voltage consensus and accurate current sharing.
