ABSTRACT
The present paper describes the modeling of Distributed Power Flow Controllers (DPFC) for studying the steady-state response and behavior of Transmission networks equipped with FACTS devices. Detailed simulations are carried out on two- machine systems to illustrate the control features of these devices and their influence to increase power transfer capability and improve system Reliability. 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. As the D-FACTS converters are single-phase and floating with respect to the ground, there is no high-voltage isolation required between the phases. The interaction between the DPFC, the network and the machines are analyzed
