Abstract :

Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC parameters. Simulation has been performed by SIMULINK/MATLAB environment. Simulation results illustrate power and accuracy of the proposed technique.
