Abstract: A transient stability is widely accepted as an important aspect in upgrading and designing power system. This study presents a transient stability analysis for IEEE-9 bus power system using Power World Simulator (PWS). This study investigates the stability by using Static Var Compensator (SVC) and operating the generators with 90% of their rated power. Then, the effect of SVC and generator control on power system transient stability will be compared. Results from simulation show that the effectiveness of operating generators with 90% of rated power and SVC on the transient stability of power system.
