In this paper, the authors propose a nonlinear control strategy of a STATic synchronous COMpensator (STATCOM) for improving transient stability of multimachine power system. The large scale and the complexity of modern power system require the nonlinear control strategy of the STATCOM. The concept of Lyapunov energy function is applied to derive the nonlinear control strategy and the proposed control based on Lyapunov energy function is locally measurable signal. The fuzzy logic control is also applied to overcome the uncertainties of various disturbances in the multimachine power system.
