Power Quality (PQ) has been a source of concern for utilities at all levels of consumption. Power electronic gadget development has had a significant influence on the quality of electric power supply. The functioning of nonlinear loads creates harmonics, which degrades the distribution system's quality. In such instances, both utilities and end consumers of electric power are becoming more worried about power quality. This implies that just a few steps must be made in order to enhance power quality. The primary emphasis of this study is on UPQC, which is a mix of series and shunt active power filters. The series APF reduces voltage-based distortions, while the shunt APF reduces current-based distortions. UPQC reduces voltage and current-based aberrations simultaneously and independently. UPQC enhances power quality by correcting for both harmonics and load current, resulting in sinusoidal source current and load voltage at the appropriate voltage level. MATLAB/Simulink was used to simulate the series APF, the shunt APF, and the UPQC.
