【摘要】：針對目前元件級的電力信息物理脆弱性評估應(yīng)用于實際大規(guī)模電力信息物理網(wǎng)時存在計算復雜度高和脆弱性保護配置難的問題,充分考慮網(wǎng)絡(luò)的介觀局域特征和社團結(jié)構(gòu),提出了一種考慮信息物理融合的電網(wǎng)脆弱社團評估方法。以電力系統(tǒng)潮流為邊權(quán)重,采用Fast Unfolding算法對電網(wǎng)進行社團劃分,根據(jù)電網(wǎng)和通信網(wǎng)對應(yīng)分層分區(qū)建設(shè)的現(xiàn)狀和實際耦合關(guān)系劃分通信網(wǎng)社團,IEEE標準算例的仿真結(jié)果證明所采用社團劃分方法的優(yōu)越性。在不同的社團內(nèi)部耦合關(guān)系下采用不同的攻擊策略攻擊電網(wǎng)中各個社團,根據(jù)整個信息物理融合系統(tǒng)故障后的最大連通子集指標評估電網(wǎng)中的脆弱社團,符合我國電網(wǎng)和通信網(wǎng)分層分區(qū)建設(shè)的現(xiàn)狀,有利于減少計算復雜度和脆弱性保護模塊化配置的難度。華中500 kV電網(wǎng)信息物理系統(tǒng)的仿真結(jié)果證明了所提方法的可行性。
[Abstract]:In order to solve the problems of high computational complexity and difficult configuration of vulnerability protection when the component level vulnerability assessment of power information physics is applied to practical large-scale power information physical network, the mesoscopic local features and community structure of the network are fully considered. In this paper, a method for evaluating vulnerable communities in power grid considering physical fusion of information is proposed. Taking power flow as the edge weight, the Fast Unfolding algorithm is used to divide the power network community. According to the current situation and the actual coupling relation of the construction of the corresponding hierarchical partition between the power network and the communication network, the simulation results of the IEEE standard example of the communication network show the superiority of the proposed method. Different attack strategies are used to attack each community in the power network under different coupling relationships within the community. The vulnerable communities in the power network are evaluated according to the maximum connected subset index of the whole information physical fusion system after failure. In line with the present situation of power network and communication network construction in China, it is helpful to reduce the computational complexity and the difficulty of modularized configuration of vulnerability protection. The simulation results of the information physical system of 500 kV power network in central China show the feasibility of the proposed method.
