Power electronics plays an important role in controlling the grid-connected renewable energy sources. Increasing penetration of photovoltaic (PV) as well as increasing peak load demand has resulted in poor voltage profile for some residential distribution networks. The voltage regulation problem in low voltage power distribution networks integrated with increased amount of solar photovoltaics (PV) has been addressed. This project proposes and evaluates the cooperative performance of a novel proportional-integral-derivative (PID) control scheme for PV interfacing inverter based on GWO optimization for regulating the voltage of three-phase grid connected solar PV system under any nonlinear and fluctuating operating conditions. The proposed scheme dynamically controls the PV inverter to inject/ absorb appropriate reactive power to regulate the voltage at point of common coupling (PCC)and provides robust response at any system worst case scenarios Regulation. The proposed techniques based PV inverter control scheme and GWO -based supervisory EMS are developed and simulated in MATLAB/ Simulink Environment.
