“…Presently, the distributed static series compensator (DSSC), which works as a D-FACTS device acts like a controlled variable conductor [7]. Due to the inability of power sources in the DSSC, it can only control the line impedance and is not most as powerful as the UPFC [8,9]. Among all FACTS devices the DPFC is the latest device which has powerful capability to control the power flow in the transmission line because it has a large number of distributed series convertors and has no dc link between shunt and series convertors, like in the UPFC which provides high redundancy to the electrical system.…”

Among the FACTS device, the distributed power flow controller (DPFC) is a superior device. This can be evaluated after eliminating the dc capacitor between shunt and series convertors of the unified power flow controller (UPFC) and placing a number of low rating single phase type distributed series convertors in the line instant of using single large rating three phase series convertors as in the UPFC. The power flow through this dc capacitor as in the UPFC now takes place through the transmission line at a third harmonic frequency in the DPFC. The DPFC uses the D-FACTS that allows the replacement of a large three-phase converter as in the UPFC by several small-size series convertors present in the DPFC. The redundancy of several series convertors increases the system's reliability of the power system. Also, there is no requirement for high voltage isolation as series convertors of the DPFC are hanging as well as single-phase types. Consequently, the DPFC system has a lower cost than the UPFC system. In this paper, the equivalent ABCD parameters of the latest FACTS device DPFC have been formulated with the help of an equivalent circuit model of the DPFC at the fundamental frequency component. Further, the optimal location in the transmission line and maximum efficiency of the DPFC along with Thyristor Controlled Series Compensator (TCSC), Static Synchronous Shunt Compensator (STATCOM) and
