This paper describes the problem of voltage sags and swells and its severe impact on non linear loads or sensitive loads. Simulations of Grid connected PV system is carried out for 5 KW system. Increasing concern on pollution and global warming has prompted Photovoltaic (PV) system as one of the potential renewable and clean energy in power system generation. Power quality issue such as Total Harmonic Distortion (THD) has become an increasingly serious concern as more PV is integrated into the grid system. This encourages an extensive study to identify the challenge in power system network. In this paper, the impact of solar irradiance to current and voltage THD is studied using the simulation model developed in MATLAB/Simulink. The results show that the developed PV model is able to predict the PV system behaviour, particularly on THD. Voltage sags/swells can occurs more frequently than other Power quality phenomenon. These sags/swells are the most important power quality problems in the power distribution system.
