The Role of Energy Storage with Renewable Electricity Generation

Abstract

Renewable energy resource like solar and wind have huge potential to reduce the dependence on fossil fuel, but due to their intermittent nature of output according to variation of season, reliability of grid affected therefore energy storage system become an important part of the of renewable electricity generation system. Pumped hydro energy storage, compressed air energy storage, flywheels, capacitors, and super conducting magnetic storage technologies have been developed, but many of these are limited in their capacity, characteristics and site dependence. Currently battery energy storage system is not much adopted within grid, but with development their density, versatility and efficiency it is observed that BESS- (battery Energy Storage system) will be adopted in large quantity.
