Abstract:

.This article proposes an efficient optimization algorithm called Mayfly Optimization Algorithm (MOA) to configure a dc-link voltage with optimal PI-controller gains to enhance a three-phase three-wire shunt active power filter's dynamic performance (SAPF). The minimization of Total Harmonic Distribution (THD) is considered an objective function by optimizing the proportional and integral gain values of the PI-controller. The performance of the optimized controller is evaluated under variable load conditions. The effectiveness of the proposed algorithm is tested using the MATLAB/SIMULINK tool and compared with other optimization algorithms such as Particle Swarm Optimization (PSO), Artificial Hummingbird Algorithm (AHA), and Archimedes Optimization Algorithm (AOA). The simulation results prove the ability of MOA to get the optimal PI-Controller gains lead to optimizing the settling time, dc-link voltage overshoot, and steady-state error which attain enhancement of the SAPF controller performance and achieves THD in the drawing source current with minimum and acceptable values according to (IEEE-519) harmonics standard.
