<p>In this paper we presents a new component within the flexible ac-transmission system (FACTS) family, called Distributed Power-Flow Controller (DPFC). The DPFC is derived from the unified power-flow controller (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. The DPFC employs the distributed FACTS (DFACTS) concept, which is to use multiple small-size single-phase converters instead of the one large-size three-phase series converter in the UPFC. The large number of series converters provides redundancy, thereby increasing the system reliability. 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. Accordingly, the cost of the DPFC system is lower than the UPFC. 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 controller is designed to achieve the most appropriate operating point based on the real power priority.</p>

Many of the Power Flow Controlling Devices are mostly used in the Transmission Lines in order to monitor the real as well as reactive power-flow variations. In this work provide an innovative power flow controlling device such as Distributed Power Flow Controller, this device also belongs to the FACTS family. This device is emerged from the Unified Power Flow Controller, there is a small differentiation between both these devices that is the common dc-link. In case of DPFC there is no existence of the dc link which connects both the converters. By design a DPFC device in MATLAB/Simulink to analyze the transmission line parameters
