摘　　要：近年来,山火灾害的发生频度与强度不断增加,对生态环境以及电网、算力网络等重要公共基础设施的危害不容忽视。为了分析算力网络与电力网络混合模式下,电网安全状态在山火灾害发展过程中的演进过程,首先,该文考虑自然环境、社会系统、算力网与电网间的耦合关系,建立山火灾害时空演化过程中电网与算力网络设备的故障模型;同时,分析电网、算力网和社会域可能的应灾措施;其次,从线路过载严重度、失负荷严重度、算力网络结构损失严重度以及碳平衡破坏度4个方面建立一套综合评估指标体系;然后,基于事件驱动模型提出山火灾害下电网安全形态的动态推演方法;最后,以某电网为算例进行仿真,结果表明,所提方法可动态刻画不同应灾方式下电网的安全形态,为提升电网运行人员面向突发山火的应急管理能力提供技术支撑。Recently,wildfires are occurring with increasing frequency and intensity,and the harm to the ecological and important public infrastructure such as power system and computing power network cannot be ignored.This paper assesses the evolution process of power system security indexes with the development of wildfires.First,the failure model of the equipment in the physical system and the computing power network is constructed by comprehensively considering the coupling relationship between natural environment and power system,and the wildfires response measures of the above systems are analyzed.Next,a comprehensive evaluation system is established from the following 4 aspects:line-overload severity,load-loss severity,structural loss severity of computing power network,and damage degree of carbon balance.Then,a dynamic deduction method of power system security morphological under wildfires based on an event driven model is established.Finally,a certain power system is simulated,showing that the proposed method can depict the security morphological of power system under different response strategies,which provides technical support for improving the emergency management ability of power system operators facing sudden wildfires.
