摘　　要：柔性多状态开关(soft open point, SOP)作为一种新型的配电网调控设备,在合理的选址定容规划下,能显著发挥促进馈线均衡、降低传输损耗、提升新能源消纳等作用。为此在考虑配电网传统调控手段的基础上提出了SOP选址定容的三层规划模型:顶层确定SOP的接入位置和容量并传递给中层;继而中层利用模拟退火算法确定常见的有载调压变压器、无功补偿电容器等传统手段的调控变量;最后底层利用粒子群算法确定SOP的运行工况。为了降低三层模型求解的复杂度,引入加权功率传输分布系数指标和网损微增率指标辅助决策。通过IEEE33配电网的算例分析表明:所提模型能够有效整定SOP接入的位置和容量,并能够给出SOP和传统调控手段的联合运行工况,考虑传统调控后的规划模型有效降低了配电网的运行费用。因此,在SOP接入规划时有必要考虑其与传统调控手段相互配合的问题,才能最大限度地提升配电网的运行经济性。Soft open point(SOP) is a new kind of flexible equipment in the distribution network. Under reasonable site selection and capacity planning, it can significantly promote feeder balance, reduce transmission loss, and enhance new energy consumption, so it is crucial to carry out reasonable site selection and capacity planning for SOPs. In this paper, a three-layer planning model for the location and capacity of SOPs is proposed: the top layer determines the installation location and capacity, and passes them to the middle layer;then the middle layer uses simulated annealing algorithm to determine the operational condition of traditional regulations such as on-load tap changers(OLTC) and reactive compensation capacitors;the bottom layer solves the operation conditions of SOPs by particle swarm optimization algorithm. Furthermore, the power transmission distribution factors and incremental rate of power loss are proposed in this paper, which effectively reduce the complexity of the three-layer model. Finally, the case of IEEE33 distribution network shows that the proposed model can effectively determine the location and capacity of SOPs, and can give the joint operation conditions of SOPs and traditional regulations, which significantly reduce the operating costs of the distribution network. Therefore, it is necessary to consider the mutual coordination of SOPs and traditional regulations in order to minimize investment cost and improve operational economic benefits.
