ANALYSIS AND PERFORMANCE OF INTER LINE POWER FLOW CONTROLLER (IPFC) FOR DAMPING LOW FREQUENCY OSCILLATIONS

Abstract

Modeling and simulation of power system equipped with FACTS type Inter Line Power Flow Controller (IPFC)
based damping controller introduced in this paper. The investigated system was a Single Machine Infinite Bus (SMIB) for
assessing the performance of IPFC based stabilizer in improvement the system stability. Particle Swarm Optimization (PSO)
is employed to determine the optimal settings of stabilizing controller using different modulating signals. The candidate
signals is selected based on the controllability indices concept. Eigenvalues and nonlinear time domain simulation of power
system is then, used to verify the effectiveness of IPFC based damping controller in mitigating the low frequency oscillations
