Popis: This paper proposes a hybrid technique for improving the voltage stability of a given system with optimal power flow solution using FACTS device installation. The hybrid technique is the combination of Improved Gravitational Search Algorithm (IGSA) and Firefly Algorithm (FA). The Thyristor Controlled Series Compensator (TCSC) device is utilized to evaluate the performance of the proposed algorithm by its optimal location and determining its capacity with optimized parameters. Therefore, the voltage stability is improved while satisfying a given set of operating and physical constraints and proposed technique is used to optimize the loading factor and apparent power flow index respectively. The algorithm is implemented in MATLAB working platform and the power flow security and voltage stability is evaluated with IEEE 30 bus transmission systems. Then, the total generated power, voltage stability, generation cost and TCSC cost are examined by changing the system load. The performance of the proposed method is perceived to be superior when compared with traditional Gravitational Search Algorithm and other techniques existing in literature.
