This paper proposes “Reduction of THD in multi bus system using MLI based DPFC with PI and FOPID” Which is composed of a Distributed Power Flow Controller is a new device within the family of FACTS. The DPFC has the same control capability as the UPFC, but with much lower cost and higher reliability. This project addresses one of the applications of the DPFC to Compensate Voltage sag in Transmissions Systems. Thirty bus system with normal VSI with five level MLI based DPFC systems are simulated and their results are presented. The comparison indicates that the THD is reduced with MLI based DPFC system. Closed loop Thirty bus system(TBS) with PI and FOPID controllers are simulated and the dynamic response indicates that FOPID Produces better response when compared to PI controller.

DPFC: Distributed Power Flow Controller, MLI: Multi level inverter, TBS: Thirty bus system
