Recently the wind power generation has attracted special interest and many wind power stations are being in service in the world. In the wind power stations, induction machines are mostly used as a generator. Since induction machines can become unstable during a fault in power system, like a step-out of synchronous machines, it is important to analyze the stability of power system including wind generators. This paper presents a consideration on the stability of induction generators from a point of view of voltage stability.

Recently, a number of electric consumers have concerned about the reliability of electricity to be served. For example, some consumers need the electricity with a higher reliability by the automation of manufacturing processes. On the other hand, some consumers need the electricity of a cheaper price even if the reliability becomes a little worse. Under such circumstances, it is necessary that power suppliers evaluate the needs of every consumers precisely and propose the most desirable measures for meeting their requirements. This paper develops a tool to analyze the reliability for high-voltage supplied consumers quantitatively. Further, this paper presents a method for evaluating the outage cost of consumers to help them choose the most appropriate measures for maintaining the reliability. The proposed method applies the fuzzy reasoning approach. The validity of the proposed method is ascertained through some numerical simulations.
