Simulink Implementation of Distributed Power Flow Controller

This paper presents the simulation results of Distributed Power Flow Controller model designed in MATLAB/SIMULINK. A simple two bus system is considered for simulation. Power flow between the two buses is obtained by providing a phase difference between the buses. DPFC consists of one shunt converter and six single phase series converters. The shunt converter is a single phase converter connected between neutral point of -Y transformer and the ground, and is powered by constant DC source. The simulation is carried out to observe steady-state behavior and also step change response of the device. This paper provides the simulation results with and without DPFC and the analysis of the results is given.
