摘要
因连锁故障引发的大电网停电事故凸显了大型电力系统的脆弱性。传统方法难以有效解释类似事故的发生机制,复杂网络理论研究的不断深入和广泛应用为此提供了新的理论工具。首先简介了复杂网络理论及其基本概念,其次探讨了用以解释电网连锁故障发生机制和结构脆弱性的理论基础,并详细阐述了复杂网络理论在电力系统拓扑结构建模、连锁故障模型研究、电网脆弱性分析以及电网关键支路和节点识别等方面的研究进展和应用情况,最后对未来的研究方向做出了展望。
Blackouts in the world over due to cascaded failures in huge power grids indicate the vulnerability of bulk power grids when they have to be faced with such a kind of faults.In view of the fact that it is hard for traditional methods to effectively explain the occurrence mechanism of similar failures,the deepgoing research on complex network theory and its widespread application provide a new means to solve the problem theoretically.Firstly,the complex network theory and its basic concepts are concisely presented;secondly, theoretical base to interpret the occurrence mechanism of cascaded failure and structural vulnerability of power grid are discussed,and the progress of the research on complex network theory and the application of complex network theory in the modeling of power system topological structure,research of cascaded failure model,analysis of grid vulnerability and identification of key branches and nodes in power grid are expounded;finally,the future research direction of complex network theory is prospected.
