Simulation Results of Closed Loop Controlled Interline Power Flow Controller System

Abstract

The Interline Power Flow Controller (IPFC) is the latest generation of Flexible AC Transmission Systems (FACTS) devices which can be used to control power flows of multiple transmission lines. A dispatch strategy is proposed for an IPFC operating at rated capacity, in which the power circulation between the two series converters is used as the parameter to optimize the voltage profile and power transfer. Voltage stability curves for test system are shown to illustrate the effectiveness of this proposed strategy. . In this paper, a circuit model for IPFC is developed and simulation of interline power flow controller is done using the proposed circuit model. Simulation is done using MATLAB simulink and the results are presented.
