ABSTRACT
This paper describes an improved method for managing power quality at the utility end of an electrical network that produces electricity using renewable energy sources. The widespread usage of irregular loads in many electrical industrial applications, including switched-mode sources, line conversion devices, and bridge rectifier devices, is the root cause of power quality problems. These loads introduce harmonic currents into the electrical grid, leading to non-sinusoidal currents and voltages with diverse disturbances. The influx of these harmonic elements into the power supply adversely impacts power systems, resulting in disturbances and noise at the user end. Consequently, the quality of electrical power has emerged as a crucial consideration in recent decades. It explores the role of active power filters as effective devices for enhancing power quality, akin to their role in reactive power compensation. Using synchronous reference frame theory, this study presents the results of using a VSI topology in a Shunt Active Filter. This technology allows for harmonic suppression within the acceptable limits of IEEE-519.
