Abstract
In the last few decades as the more increase in population occurred so the usage of electric power is increasing day by day and also the power companies are concentrating not only on quantity of the power but also the quality of the power. Here the new FACTS device is used called DPFC reduces the voltage sag and voltage swell and improves the power quality. According to growth of electricity demand and the increased number of non-linear loads in power grids, providing a high quality electrical power should be considered. In this paper, voltage sag and swell of the power quality issues are studied and distributed power flow controller (DPFC) is used to mitigate the voltage deviation and improve power quality. The DPFC (distributed power flow controller) is a new FACTS (Flexible Alternating current Transmission system) device, which its structure is similar to unified power flow controller (UPFC). In spite of UPFC, in DPFC (distributed power flow controller) the common dc-link between the shunt and series converters is eliminated and three-phase series converter is divided to several single-phase series distributed converters through the line.
Key words: Distributed power flow controller, Power Quality, Sag and Swell Mitigation.
