Abstract: This paper represents a new dimension of the Flexible AC Transmission System (FACTS) called as Distributed Power-Flow Controller (DPFC). The aim of this paper is to develop a new type of power-flow controlling device that offers the same control capability as the UPFC, at a reduced cost and with increased reliability. The new device, the so-called Distributed Power Flow Controller (DPFC), is a further development of the UPFC. The DPFC is derived from the unified power -flow controller (UPFC) and DPFC has the same control capability as the UPFC. The DPFC can be considered as a UPFC with an eliminated common dc link. The active power exchange between the shunt and series converters, which is through the common dc link in the UPFC, is now through the transmission lines at the third -harmonic frequency. The interaction between the DPFC, the network and the machines are analyzed.
