Advantages of the passivity based control in dynamic voltage restorers for power quality improvement
A better and feasible control scheme for dynamic voltage restorers is proposed. The modified PBC proposed provides tracking with zero error of any reference. The closed loop set source-DVR-PBC-load is asymptotically stable at any operating point. The proposed scheme shows more advantages than classical controllers. Simple tuning, faster response than classical controllers. Without overshoots.
