By increasing the electricity demand, the need for the application of renewable energy sources in the traditional transmission and distribution systems feels more than before. This paper presents Low Voltage Ride Through Capability enhancement of photovoltaic (PV) power plants based on battery energy storage system. This system consists of PV arrays connected to the point of common coupling (PCC), a grid tied inverter, battery energy storage system (BESS). The LVRT Capability based battery energy storage system is verified by the simulation results, which are carried out using MATLAB/SIMULINK software. So the proposed model improves the LVRT capability of the PV Power Plants in such a way that the DG power conversion unit remains connected to the grid even during fault conditions.
