This paper presented an integration of Photovoltaic (PV) system to utility grid. PV system is connected to grid via a DC-DC boost converter and three-phase three-level voltage source converter (VSC). The maximum power point tracking (MPPT) is implemented in the boost converter using incremental conductance+ integral regulator technique. This paper work presents analysis and harmonic measurement at point of common coupling (PCC) when Photovoltaic (PV) system is connected to utility grid. THD measurement of the different possible cases of PV system integrated to grid at PCC has been carried out in MATLAB/Simulink environment. Finally, harmonic mitigation and power quality improvement at PCC using passive filter and control technique of complete system is proposed and proved by different simulation results.
