Transient Stability Assessment of a Power System with a Static Synchronous Series Compensator

Static synchronous series compensator (SSSC) is widely used in power systems to control power of power system by injecting appropriate reactive power into the system. It also has the capability of improving stability and damping by dynamically controlling its reactive power output. This paper presents the energy function of a power system with a SSSC. The proposed energy function is used for transient stability assessment of a power system. This paper develops the control strategy of a SSSC for transient stability and dynamic improvement
