In this technological era, the question of the quality of voltage is rapidly increasing. New technologies are introduced and we are facing many new power quality requirements [18]. Modern industrial devices are mostly based on electronic devices such as programmable logic controllers and electronic control based drives. The electronic devices are very sensitive to disturbances and become less tolerant to power quality problems such as voltage sags, swells and harmonics. One of these devices is the Dynamic Voltage Restorer (DVR), a modern custom power device used in the most efficient power distribution networks. In this paper, the usefulness of including DVR in distribution system for the purpose of voltage sag and swell mitigation is described. This paper presents modeling, analysis and simulation of a Dynamic Voltage Restorer (DVR) using MATLAB.
