Performance analysis of solar PV based microgrid with and without BESS estimating the expected battery life

This paper depicts the performance analysis of the solar photovoltaic (PV) system with and without battery energy storage system (BESS). The superiority of the battery based system has been studied and analyzed and the expected life time of the battery has been calculated. The study has been validated appropriately when the system is subjected to fault conditions. During fault condition, the active power, reactive power, voltage and current at the point of common coupling (PCC) is compared with the solar PV based system with and without BESS system. Lastly by using probabilistic approach the expected life period of the battery is estimated. The whole system is modelled, validated and analyzed in MATLAB/SIMULINK environment.
