• Resumen

  • In this paper, a new control scheme is proposed to achieve both stability and improvement of performances for a single-machine infinite-bus power system. A high-order power system model is presented and only measurable state variables are considered to be used in the feedback control. The continuous and discontinuous excitation controllers, which have different characteristics to be chosen by engineers to meet different practical needs and objectives of power system operation, are respectively designed. The stability analysis and simulation results all show that the developed controllers are effective.
