REDUCE HARMONIC FOR PHOTOVOLTAIC INVERTERS BY SPWM CONTROL METHODS VIA SIMULATION AND EXPERIMENT ASSESSMENT OF PHOTOVOLTAIC SYSTEMS

Abstract

The article explores the implementation of Sinusoidal Pulse Width Modulation (SPWM) control techniques to mitigate harmonic distortions in photovoltaic inverters. The researchers utilized a combination of simulation and experimental assessments to evaluate the effectiveness of these methods in photovoltaic systems. The study highlights the significance of harmonic reduction in photovoltaic inverters, as harmonic distortions can lead to power quality issues and impact the overall performance of the photovoltaic system. SPWM control methods are considered an efficient approach to minimize these distortions. To assess the performance of the SPWM control techniques, the researchers employed both simulation-based experiments and real-world experiments with actual photovoltaic systems. The simulation-based approach allowed them to model various scenarios and optimize the control methods under different conditions, while the real-world experiments provided valuable insights into the practical applicability of these techniques. The observed experimental results show that the proposed method has a lower level of output harmonic distortion than the previous control method, and at the same time, the practical value closely follows the reference value and complies with the operating standards of IEC and IEEE.
