Harmonic Mitigation in a Smart Grid Using a PV-Powered Series Active Power Filter

Abstract

The rising integration of photovoltaic PV sources within SMART GRIDS introduces significant challenges related to power quality PQ, especially due to harmonic distortions that can address grid. Stability, high power quality, and optimal efficiency of all connected devices. This research focuses on compromising harmonic problems in the smart grid by proposing the use of a Series Active Power Filter SAPF as an effective solution for comprehensive harmonic elimination. The SAPF allows for the lowering of voltage harmonics. The control method using the synchronous reference frame approach SFR to detect and compensate for undesirable harmonic elements in real time. To validate the performance of the proposed approach under various loading and generation scenarios, simulation studies were performed. The findings demonstrate that the SAPF significantly reduces total harmonic distortion THD in voltage signals, therefore improving overall power quality and enhancing smart grid operation. Moreover, The SAPF surpasses traditional separate filtering methods, emphasizing its capability to enable reliable integration of renewable energy sources. This research contributes to the development of advanced power quality solutions for modern hybrid renewable energy systems, ultimately enhancing grid resilience and efficiency.
