基于复杂网络理论的船舶电网脆性源辨识方法
Brittle source identification method for ship power grid based on complex network
摘要
Abstract
[Objective]Existing brittle source identification methods have such problems as their single-perspective approach,disregard for the local and global characteristics of nodes,and insufficient consideration of the loads carried by nodes.[Methods]The method proposed herein identifies the inherent brittleness of the ship power system as the root cause of interruption and chain collapse.To establish a brittleness index,the method first considers node degree,eigenvector centrality,node cohesiveness,closeness centrality and brittle electrical betweenness from a brittleness perspective based on complex network theory.The combinatorial in-tuitionistic fuzzy analytic hierarchy process(IFAHP)and entropy weight method(EWM)with the Nash equi-librium as the coordination objective.The five indexes are then combined through comprehensive assignment to obtain a comprehensive brittleness index.Finally,the proposed brittle source identification method is valid-ated using a typical four-station annular ship grid.[Results]The method identifies four levels of brittle sources based on the network efficiency of different brittleness indexes,and the results demonstrate its ability to identify brittle sources more comprehensively and reasonably.[Conclusion]The results of this study can provide effective guidance for the prevention and control of inter-locking faults in ship power networks.关键词
