Power Quality improvement of Unbalanced Distribution System Using Fuzzy based D-STATCOM

The power quality is a more serious problem for consumers and power companies. In this paper to mitigate power quality problems such as voltage swell and voltage sag of unbalanced distribution system, a fuzzy controller based D-STATCOM is proposed. The performance of proposed fuzzy based D-STATCOM is tested on 13 bus IEEE test feeder, a D-STATCOM is introduced at bus no-632. The performance of proposed fuzzy based D-STATCOM is compared to D-STATCOM with PI control mechanism using MATLAB-simulink to address power quality issues.
