Development of probabilistic-satistical approach to the identification of weak subsystems of the power sysyem

摘要

The approach to identification of the weak elements of power system in a lot of uncertainties conditions was developed. Main uncertainty is the lack of analytical dependences among the weak criteria that requires to use fuzzy methods and algorithms. The weakness criteria of power system elements were justified. The algorithm of accident risk estimation in power system at the time interval and identification of weak subsystems with fuzzy clusterization using was developed
