摘　　要：泛在物联网的提出为配电系统应对极端天气的影响提供了更多的控制方法与手段,使得配电系统能整合所有资源实现优化调度。在此背景下,本文提出了基于泛在物联网的配电系统应对极端天气的紧急控制策略,将天然气系统与电力系统耦合建模,建立了极端天气下配电系统的紧急控制模型。接着运用蒙特卡洛模拟法来研究极端天气下配电系统的负荷损失比例,以此作为衡量本文方法优劣性的指标。最后以标准的配电系统模型作为算例分析,验证了本文模型的有效性。The ubiquitous Internet of Things provides more control methods and means for the distribution system to cope with the influence of extreme weather,enabling the distribution system to integrate all resources to achieve optimal scheduling.In this context,this paper proposes an emergency control method of distribution system to deal with extreme weather based on the ubiquitous Internet of Things.The proposed method couples the natural gas system with the power system and establishes an emergency control model for the distribution system under extreme weather.Moreover,the Monte Carlo simulation method is used to study the load loss of the distribution network under extreme weather,which is used as an indicator to measure the advantages and disadvantages of this method.Finally,the standard distribution system model is taken as an example to verify the validity of the proposed model.
