Abstract

Parallel connected distributed generation with energy storage systems (ESSs) are popular in modern sustainable microgrids. Absence of proper coordination between ESSs can lead to reduced system lifespan due to unnecessary deep discharge or premature fully charged of individual battery. This paper proposes an energy management strategy aimed at elimination of this problem by balancing the state-of-charge (SoC) of parallel connected ESSs in DC microgrids using voltage droop control which is a function of SoC and current. This was examined by simulation which shows that the proposed strategy was simple and effective under both islanded mode and grid connected situations.
