Power Flow Management and DC bus Stabilization for SPV based Battery Energy Storage System

Solar photovoltaic (SPV) energy has grown in popularity and attention as a result of its ability to generate power by converting solar irradiance into electricity using SPV cells. The SPV energy generation has gained a lot of commercial and research attention these days. The major goal of this work is the management of the SPV generated power and maintaining the DC bus voltages under varying irradiance and load conditions. The maximum power point tracking (MPPT) algorithm is used for optimal power generation under variable irradiance and load conditions. In this work, the bidirectional converter is used to control the voltage of the DC buses and to balance the power generated by the SPV array and the battery energy storage system (BESS) during day / night time. The complete solar PV system with BESS and variable load is simulated in the MATLAB Simulink platform. The results validate the proposed technique.
