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.
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
