This paper discuss about environment and rising prices of energy, more renewable energy sources are incorporated into the power grid in the form Distributed Generation (DG) Instead of using fossil fuels, energy storage like battery or ultra-capacitors coupled with the power electronic converter systems offer fast response for frequency regulation and load changes. Recent development in Lithium-ion battery technology offers advantages like high power, longer overall life, high charge and discharge efficiency. In addition to small size, and low weight Li-ion batteries can offer high energy density and storage efficiency, which make them suited for portable devices. Battery energy storage system (BESS) is the significant factor to realize flexible control and optimal operation of active distribution networks, due to its fast power adjustment capability as well as the characteristic of supply and storage competency. So the placement sizing of BESS will directly affect the active management ability with DERs and the economic benefits of active distribution network operation.
