Invulnerability Evaluation of Typical Network Structures for Medium Voltage Distribution Networks

应用复杂网络理论,提出了中压配电网网络结构抗毁性评估的方法。定义了相应的节点及节点边权值、边及边权值、初始权值等基本概念;借鉴有权网络的抗毁性评估方法,构建了中压配电网网络结构抗毁性评估模型,实现了中压配电网典型网络结构的抗毁性评估与定量排序,丰富了中压配电网的可靠性分析理论,为中压配电网网络结构的选择提供了新的依据和途径。算例验证了典型网络结构安全性的定性评价结果,证明了该方法的合理性。

Based on complex network theory,the invulnerability evaluation of typical network structures for the medium voltage distribution networks is proposed.The corresponding nodes and node weights,edges and edge weights,initial weights and other basic concepts are defined.An invulnerability evaluation model for medium voltage distribution networks is proposed for the invulnerability evaluation of weighted networks.The model can be used for invulnerability evaluation with quantitative ordering of typical network structures of medium voltage distribution networks.The method enriches reliability analysis theory of the medium voltage distribution network and provides a new basis and means for the choices of typical network structures for the medium voltage distribution network.Results from case studies confirm the validity of the qualitative assessment of the security of typical networks.The rationality of the method is also clearly shown through the case studies.
