This paper presents the mitigation of voltage sag and swells in Distributed Power Flow Controller (DPFC). The DPFC is the next generation of 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 done through the transmission lines. In DPFC many single phase converters are used instead of one three phase converter. The cost of the DPFC system is lower. Here, the capability of DPFC is observed for the transmission line based on Ant Colony Optimization (ACO). Based on the performance, we can say that ant colony optimization based DPFC gives better compensation than other Controller based DPFC. Matlab/Simulink is used to create the Ant Colony Optimization and FLC and to simulate DPFC model.
