Abstract
This study examines the effects of harmonics on power systems and their equipment, focusing on and exploring the application of different types of filters in harmonic suppression. Harmonics, a significant concern in modern power systems, leads to waveform distortion, increased losses, and reduced system efficiency. These include passive filters (PPFs), active filters (APFs) and optimisation strategies for hybrid filters. By analysing current harmonic optimisation techniques, further improvements in control algorithms and measures to optimise energy consumption and reduce costs are proposed to increase the adaptability and efficiency of filters in complex power environments. In addition, this research helps to advance the development of filtering techniques. It gives ideas that can be applied to developing renewable energy systems and smart grids, as harmonic suppression is vital in improving overall power quality and system reliability. The results of this study could guide future developments in power system optimisation to ensure smoother operation in an increasingly complex and interconnected grid.
