STATCOM control strategy based on Lyapunov energy function and fuzzy logic control for improving transient stability of multimachine power system
نویسنده
چکیده
This paper proposes 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. This paper presents the method of investigating the transient stability of the multimachine power system equipped with the STATCOM. The proposed control strategy and the method of simulation are tested on the Kundur’s inter-area power system and new England power system. It is found that the proposed nonlinear control strategy can improve transient stability of the multimachine power system. Key-Words: Flexible ac transmission system, power system, static synchronous compensation (STACOM), , fuzzy logic control, transient stability, Lyapunov, nonlinear control.
