Harmonic Distortion Assessment in the Single-Phase Photovoltaic (PV) System Based on SPWM Technique


The solar electric (photovoltaic or PV) system generates the electrical power at the day time. The current and voltage distortions are caused by the nonlinearities present in PV system which lead to the power issues. In the proposed PV system, the Insulated Gate Bipolar Junction Transistor switches the boost converter and multilevel inverter to regulate the output power of the system. In case of PV system, boost converter output is fed to an inverter to transform power from direct current to alternating current thereby inducing harmonic. The harmonic causes unnecessary overheating of the equipment, nuisance tripping of breakers and power factor reduction. The proportional integral derivative controller along with sinusoidal pulse width modulation is implemented in the proposed single-phase PV system to reduce the harmonic distortion and to improve the system performance. In the scope of this paper, the performance analysis of the PV system is done as far as accuracy, robustness and stability.
