基于元胞自动机演化的复杂电网脆弱性研究

摘要

根据元胞自动机理论在复杂系统中的应用，提出了一种新的复杂电网脆弱性评估方法———从元胞自动机的基本定义出发，建立复杂电力网络节点脆弱度指标的节点脆弱度元胞自动机模型，通过该模型演化得到节点脆弱度指标，并综合考虑电力网络的结构特性、功率特性和相邻节点间的相互影响。最后，通过 IEEE 39节点系统仿真实现对节点脆弱度的排序，并通过与其它指标的对比验证了该模型的有效性和优越性。%According to application of cellular automata theory in complex system,a kind of new evaluation method for vul-nerability of complex power grid is proposed which starts from basic concept of cellular automata and establishes a cellular automata model for node vulnerability of node vulnerability index of the electric power network,by evolution of which it is able to get node vulnerability index and comprehensively consider of structure characteristic,power characteristic and inter-active effect of adjacent nodes of the electric power network.Finally,by means of IEEE 39 node system,sorting for node vulnerability is realized,and comparison with other index proves effectiveness and superiority of this model.
