Power Electronics and Advanced Control Technologies have made it possible to mitigate power quality problems and maintain the operation of sensitive loads. Among power system disturbances, voltage sags and voltage swells are widely accepted to be the most prominent power quality problems to end users. In this study evaluation of TCC network voltage sags and swells disturbances and impacts to utilities without custom power devices is carried out. At present a wide range of flexible controllers which capitalize on new available power electronics components are emerging for custom power applications. A literature review was carried out in order to explore the status of the custom power devices that have been proposed and/or installed in the industrial distribution systems. Dynamic Voltage Restorer (DVR) based on Voltage Source Converter (VSC) was found to provide the best economic solution. The modeling and simulation of DVR using Matlab/Simulink is presented. A control system based on direct quadrature zero (d-q-0) techniques is presented. The simulation results have shown that the DVR performance is satisfactory in mitigating voltage sags and swells.
