基于CML的电力-信息网络关键节点脆弱性研究
Research on Vulnerability of Key Nodes in Power-information Network Based on CML
摘要
Abstract
In order to study the vulnerability of power-information coupling network under attack,this paper analyzes the vulnerability of key nodes.Firstly,the key nodes of the network are identified based on DC,BC and CC,and the power-information dependent network dynamics model is constructed by using the coupled image lattice to simulate the dynamic cascading process caused by the failure of each key node under different scenari-os.The node loss ratio and network connectivity entropy are used to quantify the vulnera-bility of the network to external disturbances.Taking IEEE57 as an example,it is found that the coupling network is more prone to"secondary cascading"or even multiple casca-ding,and the cascading failure under BC is the most rapid.With the increase of propaga-tion coefficient and disturbance,the node loss ratio and network connectivity entropy reach the threshold,and the network will not show stronger vulnerability.关键词
