Abstract: One among the contemporary power electronic controller in distribution system is Dynamic voltage restorer (DVR) used to guard the customers from the voltage variations. DVR output compensating signals organize the voltage signal in distribution system. DVR is triggered from the control pulses generated from the control methodology. The paper presents the different control methodologies for DVR to regulate the voltage wave in distribution system from sag/swell. Simulation analysis is conveyed by using MATLAB/SIMULINK tool and simulation results indicate the ability of DVR to regulate sag/swell in distribution system.

Keywords: Compensation, voltage sag, voltage swell, sensitive load, DVR.
Scope of the Article: Renewable Energy Technology
