A Study to Investigate the Power Quality Issues for Using DVR to Mitigate Voltage Sag

Abstract

Power Quality is an important problem of recent days. Many utilities from around the world is finding very difficult to meet the energy demands leading to the load shedding and other power quality problems. From decades, power quality has always been an important issue. Much research has been done to monitor and improve the quality of power. Many measures have been implemented and even we have gone so far in improving as well as maintaining the quality of power. Dynamic Voltage Restorer (DVR) is of great importance in present power system because of consistent problems related to the power distribution including the voltage sag and voltage swell.
