Abstract

This paper built photovoltaic (PV) grid power system model in MATLAB/Simulink, and researched some factors which can influence the current harmonics of grid for single grid-connected photovoltaic (pv) inverter. These factors include irradiance, environmental temperature, the control method of inverter, the imbalance of the three-phase grid and the voltage harmonics of the grid. This paper also studied the condition that multiple photovoltaic grid inverters can weaken the grid current harmonics in the point of common coupling (PCC).
