This paper describes the problem of voltage sags and swells and its severe impact on non linear loads or sensitive loads. The dynamic voltage restorer (DVR) has become popular as a cost effective solution for the protection of sensitive loads vol

simulation of Dynamic Voltage Restorer in MATLAB simulink software.

this file is simulation of dynamic voltage restorer (DVR) that is simulated by MATLAB/SIMULINK. the power system has 3 bus and 2 load that one of them is considered critical load. the DVR duty is compensating voltage sag or swell.in fact this work is
