Enhancement of Power Flow by Using Distributed Power Flow Controller (DPFC)

Abstract

This paper presents a new concept of power flow controlling device (PFCD) that proposes the same control ability as the UPFC, at a reduced the cost and with an growing the reliability of the device. That new device is, so-called as Distributed Power Flow Controller (DPFC). The DPFC is the advanced development of the UPFC. The DPFC eliminates the common DC link within the UPFC, to enable the independent operation of the shunt and the series converter.. In a traditional power system, the electrical energy is generated by centralized power plants and flows to consumers via the transmission and distribution network. The rate of the transported electrical energy within the lines of the power system is referred to as “Power Flow”, to be more
specific, it is the active and reactive power that flows in the transmission lines. The proposed control methods like PI control, sliding mode control (SMC). The control approach used for the DPFC balances the power flow and regulates the voltage with stable operation. At the end, this paper presents the system level, which includes the DPFC applications to improve power system
controllability and stability of the DPFC for real networks.
