中文摘要:

新型电力系统的新能源占比逐渐增多，使得新型电力系统呈现低碳化、智能化、多元化、安全经济化的发展趋势，对网络安全的要求越来越高。随着国民经济飞速发展，新型电力系统电力拓扑结构(物理层)与通信网络(信息层)的耦合依赖关系日益增长，这虽然有利于电力系统规模扩张，但是极易产生级联失效故障，并助推故障加剧，发生大规模停电事故。基于此，以新型电力系统的信息物理系统(cyber-physical system，CPS)级联失效为研究对象，构建了基于马尔可夫的电力级联失效动态耦合模型，刻画了电力节点与通信节点之间的多级动态耦合关系，分析了模型的鲁棒性，给出了电力CPS级联失效的关键节点识别算法，提出了基于加权综合指数与影响因子的路径优化模型。实验结果表明设备安全性对新型电力系统CPS级联失效通信路径优化起着决定性作用，可有效节约0.52%的网络消耗能量，能量最低，路径最优。

英文摘要:

The proportion of new energy in novel power system is gradually increasing, leading to a development trend of low carbonization, intelligence, diversification, safety and economy in novel power system, and an increasing demand for network security. With the rapid development of the national economy, the coupling dependence between the novel power system topology (physical layer) and communication network (information layer) is increasing day by day. Although this is conducive to the expansion of the power system scale, it is extremely prone to cascading failure faults, which can exacerbate faults and lead to large-scale power outages. On this basis, taking the cascading failure of the cyber physical system (CPS) in novel power system as the research object, a Markovbased dynamic coupling model for power cascading failure is constructed. The multi-level dynamic coupling relationship between power nodes and communication nodes is characterized, and the robustness of the model is analyzed. A key node identification algorithm for cascading failure of power CPS is proposed, and a path optimization model based on weighted composite index and influencing factors is proposed. The experimental results indicate that device safety plays a decisive role in optimizing the communication path for CPS cascading failures in novel power system, which can effectively save 0.52% of network energy consumption, with the lowest energy and optimal path.
