The present paper describes the Distributed Power Flow Controllers (DPFC) for improving the Power Transfer Capability and System Reliability 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, in DPFC through the transmission lines at the third-harmonic frequency. The interaction between the DPFC, the network and the machines are analyzed.

Abstract


The present paper describes the Distributed Power Flow Controllers (DPFC) for improving the Power Transfer Capability and System Reliability 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, in DPFC through the transmission lines at the third-harmonic frequency. The interaction between the DPFC, the network and the machines are analyzed.
