The series compensating FACTS device Interline Power Flow Controller (IPFC) for series compensation of Active and reactive power with the unique capability of power flow management among the multiple transmission lines in transmission system. During the disturbances in power system, the stability of system causes deviation from stable operation and causes variation in different parameters of power system like load angle and Rotor speed. To suppress the oscillations in load angle and rotor speed, the Fuzzy logic controller (FLC) with IPFC is proposed in this paper to improve the stability of power system. IEEE 14 bus system using IPFC with FLC is considered for analysis. Analysis is carried out using MATLAB/Simulink for different fault conditions.
