Abstract: It is widely accepted that power system stability is an important aspect in planning and promoting electric power system. This paper presents the transient stability analysis of the three-machine nine-bus test system using MATLAB. Generator angular frequency is a reliable indicator of the stability of the power system. Change in load, power generation or fault causes a fluctuation of the speed of the generators in the power system, resulting in fluctuation of the angular frequency of the power system. So rate of change of angular frequency is used as indicator of the transient stability of the system and measures taken to maintain stability and frequency of the system. This paper presents a coordinated control tuning of power system stabilizer (PSS) with Static Synchronous Series Compensator (SSSC) by firefly algorithm to enhance the power transient stability.
Keywords: Firefly Algorithm, Power system stabilizers, Static Synchronous Series Compensator (SSSC).
