Battery energy storage systems (BESSs) have attracted significant attention in managing RESs [12], [13], as they provide flexibility to charge and discharge power as needed. A battery bank, working based on lead–acid (Pba), lithium-ion (Li-ion), or other technologies, is connected to the grid through a converter.
