Abstract

The distributed power flow-controller (DPFC) modified from UPFC for increasing system stability and reducing costs. 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 DPFC has the same control capability as the UPFC, which comprises the adjustment of the line impedance, the transmission angle, and the bus voltage. The objective of this review paper is to study principle of DPFC and analysis the performance to improve the voltage profile. Detailed simulations were carried out to illustrate the control features of these devices.
