Power management on DC microgrid with new DC coupling based on fuzzy logic

<span>In DC microgrids, the utilization of renewable energy results in disruptions. This paper proposes coordinated control multiple batteries using a fuzzy logic controller (FLC). The goal is to regulate voltage and power on microgrid. Method used with modified coupling configuration. proposed new topology uses 2 photovoltaic (PV) arrays. Part PV array output will be stored battery, part provided bus. Apart from being connected bus, array1 (PV-A1) array2 (PV-A2) are also battery 1 (B1) (B2) via buck converter. Instead, 3 (B3) public grid source. study show that FLC deviation bus lower when comparison proportional integral (PI) controller. As well, response time produces settling 0.5 seconds an overshoot 0.5%, while PI <span>controller 1.15 27.6%.</span></span>
