A contribution to modelling and study of SSSC compensator employing firefly algorithm

Abstract

In the present scenario, Flexible Alternating Current Transmission (FACT) devices are broadly utilized as a part of the various power system. Because the application of FACTS technologies will increase attainable interferences in operational tasks of controllers. This paper describes the single machine infinite bus (SMIB) system, and to enhance the damping oscillation a new generation of FACT device such as Static Synchronous Series Compensator (SSSC) unit have been employed. The primary point of concern of the suggested method is better damping and overshoot reduction oscillation and by that enhancing the power oscillation damping. To tune the controller parameter effectively, Firefly Algorithm (FA) is applied. Both remote and local signals with related time delay are reflected in the model. MATLAB/SIMULINK software is used to analyses the SMIB with SSSC controller. The performance of the system is confirmed with changing parameter and diverse loading environments with delay.
