摘　　要：为提升配电网络应对突发性事件而提升可靠性,提出了考虑网络脆弱性的配电网络重构模型。首先分析了脆弱性评估流程,建立了以成本最小为目标的缺供电量优化模型。包括潮流约束、网络安全约束、中断负荷约束以及网络辐射性约束。利用选择粒子群优化方法进行优化求解。针对提出的模型进行了仿真分析,说明了所提出模型的有效性。In order to improve the reliability of distribution network in response to emergencies,a distribution network reconfiguration model considering network vulnerability is proposed.Firstly,the vulnerability assessment process is analyzed,and the power shortage optimization model aiming at the minimum cost is established.Including power flow constraints,network security constraints,interruption load constraints and network radiation constraints.The optimization solution is carried out by using the selective particle swarm optimization.The simulation analysis of the model proposed in this paper shows the effectiveness of the proposed model.
