摘　　要：在电力系统运行中,基于母线-支路模型和开/闭输电线路的网络拓扑优化(NTO)已被提出并作为一种缓解阻塞的工具来降低运行成本,但该模型无法提供常规变电站切换(如母线分离)的详细信息。为此,基于NTO模型提出了收紧边界的方法以保持可靠性并加速计算,进而缓解阻塞。同时,根据变电站的灵敏度分析,提出了将网络聚类应用于阻塞区域的方法以重构变电站主接线对象,从而显著减少与断路器开关相关的二进制变量数量。结果表明,将NTO模型应用于IEEE 118节点测试系统,与母线-支线切换相比,其切换动作次数明显减少,在消除阻塞方面效果显著。In the operation of power systems,network topology optimization(NTO)based on the bus branch model and open/closed transmission lines has been proposed as a tool to alleviate congestion and reduce operating costs.However,this model cannot provide detailed information on conventional substation switching(such as bus separation).Therefore,based on the NTO model,this paper proposes a method of tightening the boundary to maintain reliability and accelerate computation to alleviate congestion.At the same time,based on the sensitivity analysis of the substation,a method of applying network clustering to the blocking area is proposed to reconstruct the main connection object of the substation,thereby significantly reducing the number of binary variables related to circuit breaker switches.The results show that applying the NTO model to the IEEE 118 node testing system significantly reduces the number of switching actions compared to bus branch switching,and has a significant effect in eliminating blocking.
