Abstract: This paper represents the stabilizing control for electric power systems by means of the superconducting magnetic energy storage (SMES). After describing the concept of stabilization by the SMES, using the simplest power system model, we show a method for analyzing a more complex model of power systems including the SMES. As for the stabilizing control methods, we propose the bang-bang control of the control angle a of the SMES thyristor bridge, and the control of α by the feedback of the angular velocity deviation ⊿ω of the generator rotor. We then apply them to a one-machine infinite-bus system to examine their effects. After that, the system's damping effects of the feedback control of the SMES on a multi-machine system are investigated, using a sample 10-machine system. Lastly, the relationship between the SMES location and the damping effect is discussed.
