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.
It allows for time-shifting power, charging from solar, providing grid support, and exporting power back to the grid. When an ESS system is able to produce more power than it can use and store, it can sell the surplus to the grid; and when it has insufficient energy or power, it automatically buys it from the grid.
