Integrated Application of STATCOM and SMES to Improve Power Swings Damping Based on Direct Lyapunov Method

In this paper a comprehensive approach is presented to improve power swings damping based on direct Lyapunov method. The approach combines
superconducting magnetic energy storage (SMES) system with static synchronous compensator STATCOM). Considering the energy absorption/injection ability of SMES, in transient states the combination exchanges both active and reactive powers with power system
