In this paper, we introduced a new series-shunt type FACTS controller called as distributed power flow controller to improve and maintain the power quality of an electrical power system. This DPFC method is same as the UPFC used to compensate the voltage sag and the current swell these are voltage based power quality problems. As compared to UPFC the common dc link capacitor is removed and three individual single phase converters are used instead of a three phase series converter. Series referral voltages, branch currents are used in this paper for designing control circuit. The evaluated values are obtained by using MATLAB/SIMULINK.
