Abstract This paper proposes the optimum controller for shunt active filter (SAF) to
mitigate the harmonics and maintain the power quality in the distribution system. It consists
of shunt active filter, Voltage Source Inverter (VSI), series inductor and DC bus and nonlinear load. The proposed hybrid approach is a combination of Particle Swarm
Optimization (PSO) and Artificial Neural Network (ANN) termed as PSOANN. The PI
controller gain parameters of kp and ki are optimized with the help of PSOANN. The
PSOANN improves the accuracy of tuning the gain parameters under steady and dynamic
load conditions; thereby it reduces the values of… More >
