Description
Summary:This paper proposes an improved grid-connected system with PhotoVoltaic (PV) and battery storage under non-uniform irradiance conditions. We first develop an implementation of the system while considering non-uniform Partial Shading (PS) conditions which several literatures do not consider. Next, we propose an improved PV Maximum Power Point Tracking (MPPT) algorithm, which have shown its superiority for non-uniform irradiance conditions compared to another MPPT algorithm specifically in terms of power convergence efficiency. Finally, we validate the performance of the grid-connected architecture by showing battery charging and discharging in situations of excess and deficient PV supply and also the grid supplying to the load in case of deficiency in both battery State of Charge (SoC) and PV supply.
