Abstract
Grid connected PV system is considered as one of the promising technologies to meet the growing demand of energy in present scenarios. This paper studies the impact of increased penetration of PV generation on power quality parameters in a power network. The performance analysis of grid connected photovoltaic power systems is carried out under different levels of solar irradiance and also under varying load conditions. For this simulations are carried out on a 100 kW grid connected PV system which is designed and modelled in MATLAB/Simulink software. The simulations results are presented considering Power Quality (PQ) issues such as voltage variations at the Point of Common Coupling (PCC) and current and voltage Total Harmonic Distortion (THD) at different load demand/types conditions.
