The dc microgrid consists of renewable energy sources, energy storage system, and loads. The power output of these RESs is intermittent in nature. This raises the problem of power sharing among the sources and bus voltage regulation. This article proposes a new fuzzy logic based control scheme to mitigate power sharing mismatch during the variation in available power of RESs. It exploits the nonlinear mapping between sources power sharing with variation in available power. The novel fuzzy logic controller improves the system bus voltage regulation under different operating conditions. It is simple in design and does not need knowledge about a complex mathematical model of the overall system. The experimental results are presented which shows the superiority of the proposed control under different operating conditions over the conventional control.
