Energy Storage Technology is one of the major components of renewable energy integration and decarbonization of world energy systems. It significantly benefits addressing ancillary power services, power quality stability, and power supply reliability.
Energy storage creates a buffer in the power system that can absorb any excess energy in periods when renewables produce more than is required. This stored energy is then sent back to the grid when supply is limited. It also plays an important role in times of any grid emergency, it can supply the grid with enough power in a short duration to
