This paper presents a study comparison of Flexible AC Transmission System (FACTS) device with Power System Stabilizer (PSS) to improve the response of transient stability of the multi-machine power system. In this paper, the Static Synchronous Compensator (STATCOM), the Static Var Compensator (SVC) and Unified Power Flow Controller (UPFC) can significantly improve the power stability, thus enhancing the overall stability of the system during the disturbance. In addition, the active power control of the power system, SVC, STATCOM and UPFC play an additional role in enhancing the stability of the terminal and thus play a vital role in controlling system stability. This research has looked at the specific performance and comparison of three devices as far as damping is concerned about system vibrations. The MATLAB software is using to study the impact of damping oscillations in a stability power system based on PSS and FACTS devices. The results showed significant improvement in transient stability when FACTS are applied by significantly reducing the time of error adjustment in the power system and effectively reducing network oscillation in contrast with when the devices are not applied.
