Abstract

This paper proposes a heuristic control of the shunt active power filter for power quality enhancement. The present-day utility system as a linear model is unsatisfactory and the steps are laid down to discuss utility system as a nonlinear model. This paper deals the major power quality disturbance current harmonics with robust heuristic algorithm like the gravitational search algorithms. In this context, the shunt active filter is utilized as a active current controller. The harmonic content reduction in the source current is carried out with optimal tuning of the PI controller. The basic instantaneous active and reactive power theory optimized with GSA is used to generate the reference current signals required for compensation. The hysteresis band current controller is used to perform the switching operation of Voltage Source Inverter. Simulations are carried out in the MATLAB and SIMULINK environment.
