Optimum control for dynamic voltage restorer based on particle swarm optimization algorithm

This article <span>addresses a variety of power quality concerns, including voltage sag and swell, surges, harmonics, so on, utilizing dynamic restorer (DVR). The proposed controller for DVR is proportional plus integral (PI) controller. Two methods are used tuning the parameters PI controller, trial error intelligent optimal method. utilized method particle swarm optimization (PSO) Results depicted that using tuned by PSO has improved performance than in term rise time, maximum overshoot settling as well total harmonic distortion (THD). These improvements applicable swell conditions.</span>
