Popis: This paper deals with the integration of two stage solar photovoltaic (PV) system with the battery energy storage system (BESS) to a single-phase grid. The proposed system demonstrates multifunction capabilities on the grid side such as converting and feeding solar DC power to AC grid, harmonics elimination and reactive power compensation from supply current due to nonlinear loads connected at the point of common coupling (PCC). The use of a multifunctional inverter reduces the cost and it increases the efficiency of the system by a large extent. The system also demonstrates the battery dynamics during dynamic loads and solar insolation, thus leveling the PV power fluctuations. The control implemented for each converter is simple and easy to implement. It adapts itself to worst environmental conditions such as unavailability of solar energy during night and unavailability of energy storage due to malfunction/deep discharge of the battery. The system is designed for a peak power of 5kW. Experimental results on the developed system are demonstrated at a nonlinear rectifier load.
