Stability improvement and power flow control of a grid connected offshore wind farm system using IPFC

Abstract

Power flow control and stability improvement of a transmission line connected with three energy sources for different loads are studied, in which Flexible AC Transmission system (FACTS) controllers are used to balance the power flow in transmission lines and increase the effective use of transmission line by improving stability of the power system. The Interline Power Flow Controller is the FACTS device used, it consists of static synchronous series compensator to reduce low frequency oscillation, and damping produced is reduced by designing an oscillation damping controller. Among the three sources of energy to transmission line one is considered as renewable wind farm that are capable of producing 9MW power. A Simulink system is developed for the proposed system and the output waveforms are analyzed for various parameters such as voltage, real and reactive power.
