The physical laws which govern the flow of 并將該指標應用于電力網(wǎng)關鍵節(jié)點識別。對IEEE 39 節(jié)點系 power through network were studied. To solve the problem that 統(tǒng)和湖南某地區(qū)電網(wǎng)進行分析計算，時域仿真結果表明，所 classical complex network model can not explicitly incorporate 提指標比拓撲度指標更為合理有效。 the laws governing the flow of electricity within networks, the 關鍵詞：關鍵節(jié)點；復雜網(wǎng)絡；電氣距離；節(jié)點電氣耦合連 electrical distance between pairs of nodes was calculated 接度；無標度特性；脆弱性指標 according to superimposed principle based on the information contained in the character of power network. The characteristic 0 引言 identification model of power grid was built with
