| Abstract: | In accordance with the high dimensional characteristics of voltage stability in power system,feature selection method can reduce dimensions effectively.This paper proposes a feature selection method for static voltage stability assessment based on overlapped probability,and constructs decision tree for the assessment.Its application in the IEEE-39 node test system has verified that the simplest combination generated by the proposed method can achieve high accuracy in the static voltage assessment. |
