Photovoltaic or wind turbine system installed around world has been increased dramatically in the last decade. Unfortunately, these systems are uncontrollable and dependent on environmental conditions i.e., sun or wind. As a consequence, increasing connections of those systems to the grid can lead to the stability problem of the utility network or even the failure because of their uncontrollability. Battery energy storage system(BESS) can be used to control the output fluctuations of renewable
