Abstract: Dynamic Voltage Restorer (DVR), for some important reasons, is utilized inPower Distribution for protecting loads especially critical loads against somepower quality issues like sag, swell, harmonics and faults. Fast transientresponse for compensating voltage quality is an unavoidable factor. Differentcontrol topologies have been applied to this device. In this project, a DVR isdeployed to preserve a critical load that is connected in parallel with thegrid and A wind turbine. Several situations of power quality issues have beenconsidered. The simulation results of a proposed system that has beenimplemented in MATLAB Simulink show how DVR is effective for protecting loads.
