摘　　要：针对智能配电网供电恢复问题,提出了一种基于SOP的供电恢复联合优化策略。首先,基于智能软开关的控制模式原理,在网络等效的基础上,建立了含SOP的供电恢复联合优化模型;其次,采用兼具快速收敛性和鲁棒性的原始-对偶内点法来求解;最后,以某市的互联馈线为例,验证了联合优化模型的可行性及优化算法的有效性,体现了SOP在供电恢复中的优势。Aiming at the problem of power supply restoration in smart distribution network,this paper proposes a joint optimization strategy based on SOP for power restoration.Firstly,based on the control mode principle of soft open point,ajoint optimization model of power supply restoration with SOP is established on the basis of network equivalence.Secondly,the original-dual interior point method with fast convergence and robustness is used to solve the model.Finally,taking the interconnected feeder of a city as an example,the feasibility of the joint optimization model and the effectiveness of the optimization algorithm are verified,which shows the advantages of SOP in power restoration.
