Distributed Power Flow Controller (DPFC) is a new concept in FACTS Technology. It is derived from
UPFC by eliminating DC link between the shunt and series converter. It has the same control capability of controlling
all the system parameters as that of UPFC and its series converter is distributed over the transmission line which is
distributed static series converter which is single phase converter. It is highly reliable, higher controllability and low
cost as compared to UPFC. It employs two converters i.e. series and shunt converter and each converter needs a
controlling circuit and an additional central controlling circuit which provides reference voltage to series and shunt
controlling circuit. This paper gives an overview of controlling scheme of DPFC. The SRF method is used as control
strategy for DPFC. The simulation is carried out in MATLAB SIMULINK.
