Breaking innovations in power electronic devices which are alternative to long-distance alternating current transmission line has provided better solution in driving the transition of power systems toward a carbon-free paradigm while maintaining the current standards of quality, efficiency, and resilience. Thus, application of Voltage Source Converter (VSC) based Flexible Alternating Current Transmission System (FACTS) devices such as Static Synchronous Compensators (STATCOM) and Static Synchronous Series Compensator (SSSC)  have been widely recognized as most advanced and powerful tools in providing a veritable way to control the stability in power system during disturbance This study therefore, focuses on reviewing these aspects through comprehensive study of integration of STATCOM and SSSC controller in power system
