This paper presents an advanced component of flexible ac transmission system called Distributed Power Flow Controller. DPFC is derived from the concept of unified power flow controller. The DPFC can be considered like a unified power flow controller with an eliminated common dc link. 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 performance of the distributed power flow controller is verified in Matlab/Simulink.
