Nonlinear adaptive controller design of SSSC for damping inter-area oscillation

This paper presents a novel nonlinear adaptive control scheme of static synchronous series compensator (SSSC) to enhance the transmission power and damping of inter-area oscillation mode for multimachine power system. The SSSC device was treated as a first order voltage resource and the multimachine system was simplified into a two-machine model. Based on the exact feedback linearization theory, Lyapunov stability theory, and adaptive control law, the nonlinear adaptive controller of SSSC is derived. Unknown system parameters are considered for improving robustness. The simulation results validate the efficacy of the proposed controller.
