AB  - Problem statement: Thyristor Controlled Series Capacitor (TCSC) and Static Var
Compensator (SVC) have been individually applied to improve stability of power system.
Approach: This study presents the coordination of a TCSC and SVC for improving power system
stability. The swing curves of the three phase faulted power system with various cases are tested and
compared. Results: The swing curve of system without FACTS devices has undamped oscillation.
The system with a TCSC or a SVC can increase damping of power system whereas the system with
coordination of a TCSC and a SVC provides the best results of stability improvement
Conclusion: From the simulation results, the stability of power system can be much better improved
by coordination control of a TCSC and a SVC.
