      abstract = {The increasing penetration of power electronic converters, nonlinear loads, and distributed generation units into modern power systems has significantly heightened the problem of harmonic distortion, adversely affecting power quality and system reliability. This paper presents an investigation into power system harmonic reduction using a Shunt Active Power Filter (SAPF). The shunt active filter is designed to inject compensating currents that counteract harmonic components drawn by nonlinear loads, thereby improving the overall power quality. A control strategy based on instantaneous reactive power theory (p?q theory) is implemented to generate reference currents, which are tracked using a hysteresis current controller to achieve fast dynamic response and accurate compensation. Simulation results demonstrate the effectiveness of the proposed SAPF in reducing Total Harmonic Distortion (THD) of source currents to within IEEE 519 standard limits, while also improving power factor and load balancing. The findings confirm that shunt active filtering provides a flexible and efficient solution for mitigating harmonics in power distribution networks, ensuring stable and reliable operation under varying load conditions.},
