【摘要】：為獲得電力網(wǎng)絡(luò)結(jié)構(gòu)的本質(zhì)特性,對(duì)IEEE標(biāo)準(zhǔn)測(cè)試電網(wǎng)和一系列規(guī)模不等、發(fā)展歷程不同、建設(shè)水平各異的實(shí)際電網(wǎng),進(jìn)行復(fù)雜網(wǎng)絡(luò)典型特性分析和結(jié)構(gòu)脆弱性的模擬仿真。分析電力網(wǎng)絡(luò)節(jié)點(diǎn)度數(shù)在對(duì)數(shù)坐標(biāo)和半對(duì)數(shù)坐標(biāo)下的分布特性,探求電力網(wǎng)絡(luò)特征路徑長(zhǎng)度、聚類(lèi)系數(shù)的統(tǒng)計(jì)特性及其與網(wǎng)絡(luò)規(guī)模之間的關(guān)聯(lián)關(guān)系,基于凝聚算法考察電力網(wǎng)絡(luò)不同模型下的模塊度。所分析的電網(wǎng)不具有無(wú)標(biāo)度特性,小世界特性與網(wǎng)絡(luò)規(guī)模相關(guān),而社團(tuán)特性明顯,表明社團(tuán)特性是電力網(wǎng)絡(luò)普適的結(jié)構(gòu)特性。以負(fù)荷節(jié)點(diǎn)可連接的電源節(jié)點(diǎn)比例衡量電力網(wǎng)絡(luò)的整體性能,考察社團(tuán)間聯(lián)絡(luò)線遭蓄意攻擊時(shí)網(wǎng)絡(luò)性能的變化。所分析的電網(wǎng)均表現(xiàn)出脆弱性,進(jìn)一步驗(yàn)證了社團(tuán)特性是電力網(wǎng)絡(luò)結(jié)構(gòu)普適的特性這一結(jié)論。
[Abstract]:In order to obtain the essential characteristics of power network structure, the typical characteristics of complex network and the simulation of structural vulnerability are analyzed for IEEE standard test grid and a series of actual power grid with different scale, development process and construction level. This paper explores the characteristic path length of power network, the statistical characteristics of clustering coefficients and the relationship between clustering coefficients and network size, and examines the modularity of different power network models based on the agglomeration algorithm. The structure characteristics of power network are universal. The overall performance of power network is measured by the proportion of connected power nodes. The changes of network performance when the inter-community tie lines are deliberately attacked are investigated.
