摘要
提出运用复杂网络理论从结构的角度分析电力调度数据网的复杂性及脆弱性。现有的电力调度数据网大致可分为双星型和网状2种典型结构,从统计特征参数、度数累积分布以及介数累积分布3个方面对这2种电力调度数据网的结构进行了分析,发现双星型网是典型的无标度网络,而网状网是典型的小世界网络。继而以单一故障和连锁故障分别衡量了2种网络的静态脆弱性和动态脆弱性。结果表明:1)电力调度数据网的脆弱性与其网络结构有很大的联系,单一故障时,双星型结构的调度数据网对选择性攻击表现得更加脆弱;2)双星型结构的调度数据网不容易发生连锁故障,网状结构反之。连锁故障时故障概率较高的节点仍集中在介数高的节点。
A new structural complexity and vulnerability analysis method for electric power system dispatching data network （EPSDDN） based on complex network theory is proposed. The existing structure of EPSDDN can be categorized into two typical structures： double-star and mesh, and is analyzed from the statistically characteristic parameters and cumulative distribution of degree and betweenness centrality of these two typical network structures. Simulation result shown that the double-star network is a typical scale-free network while the mesh network is a typical small-world network. The static and dynamic vulnerability of the typical networks are analyzed using single fault and cascading outage respectively. Simulation result indicates that the vulnerability of EPSDDN has close relationship with network structure. The mesh network is much more robust to selective single failure than the double-star network, while the cascading failures are much easier to take place in the latter, and the vulnerable nodes concentrate on the nodes which have high betweenness centrality.
