Reducción de sobrecarga armónica mediante el filtro ac activo de rango completo empleando el algoritmo de Harris Hawks para determinar la ubicación óptima

Abstract

This study proposes a strategy to mitigate harmonics and improve power quality. The solution is based on the implementation of a Shunt Active Power Filter (SAPF). The optimal location of the SAPF is determined using the Harris Hawks Optimization (HHO) algorithm. This method minimizes Total Harmonic Distortion (THD) and optimizes the Power Factor (PF). Additionally, it complies with voltage constraints and THD limits as per IEEE 519-2014 standards. The SAPF is designed to compensate harmonic currents and inject reactive power into the selected bus. The results show that bus 7 is the most suitable location. At this bus, THD is reduced from 8% to 1.5%. Simultaneously, the PF improves to values close to 1.0. Moreover, voltage levels in all buses are stabilized, ensuring a supply within operational limits. The HHO demonstrates its capability to identify optimal solutions accurately and efficiently.
