Abstract :
A new method based on fuzzy logic is proposed for steady-state security analysis. The method has been developed for the Dutch 380 kV transmission system. The security status of the power system´s operating condition is recognized from data from a SCADA system, from global knowledge and some operation characteristics of the power system. The method can classify the power system´s operating condition into normal/alert state. For the alert state, it provides information about the severity and pertinent contingencies that may cause insecurity. The security assessment can follow different strategies such as risk awareness. A risk index shows the risk
