Impact assessment of irradiance and temperature variation on PV system current harmonics injection

This paper presents the impact assessment of solar irradiance and temperature variation on the photovoltaic (PV) system current harmonics injection at the point of common coupling. The cases when the PV system is connected to the weak and strong (rigid) distribution grid are analyzed. Based on the developed simulation model in MATLAB/Simulink and obtained results, conclusions are drawn regarding the current harmonics injection and their impact defined by standards and technical recommendations.
