AB  - Problem Statement: Static Synchronous Compensator (STATCOM) and Static
Synchronous Series Compensator (SSSC) have been individually applied to improve stability of power
system. Approach: This study presents the coordination of a STATCOM and SSSC 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 STATCOM or a SSSC can increase damping of power system whereas
the system with coordination of a STATCOM and a SSSC 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 STATCOM and a SSSC.
