摘　　要：新能源高比例接入会导致配电台区出现网架结构薄弱、局部负荷分配不均等承载力不足问题,通过台区柔性互联可解决上述问题,但电力电子式互联装置过高的投资及运维成本限制了其广泛应用。为此,该文提出一种面向配电台区经济性及综合承载力提升的旋转潮流控制器(RPFC)双层规划模型。首先,建立RPFC的稳态潮流模型,提出含RPFC的配电台区柔性互联结构;其次,构建含RPFC的配电台区双层规划模型,上层为RPFC选址定容层,以配电台区总投资成本最小为目标确定RPFC最优容量与位置,下层为运行优化层,构建考虑安全性、经济性、灵活性的综合承载力指标体系,并以综合承载力最高为目标优化RPFC运行功率;然后,为提高寻优速度和精度,提出一种改进引力场结合二阶锥规划的混合优化算法求解该双层规划模型;最后,将所提模型与其他规划模型进行对比,结果表明所提模型在降低配电台区总投资成本的同时提高了配电台区综合承载力。As a vital component of the power system,the power supply capacity within distribution station areas exerts a direct influence on urban economic development and the enhancement of residents'living standards.With the escalating integration of renewable energy sources,electric vehicles,and diversified load connections,these areas are confronted with significant challenges,including weak grid structures,uneven local load distribution,and inadequate carrying capacities.While the power electronic flexible interconnection device offers a potential solution to these issues,its high investment and operational costs hinder widespread adoption.In contrast,the rotary power flow controller(RPFC),an electromagnetic device,presents advantages such as cost-effectiveness and resilience to impacts.By enabling spatial regulation of line power flow,the RPFC can effectively bolster the bearing capacity of distribution areas,thereby enhancing their overall carrying capacity.Firstly,the steady-state power flow model of the RPFC is established.The RPFC is a flexible interconnection device that regulates power flow based on the rotary phase shifting transformer(RPST)principle.Adjusting both the amplitude and phase of the series voltage allows for precise control of power flow along the line.Based on this,a flexible interconnection structure of the distribution station area containing RPFC is proposed.Secondly,a bi-level programming framework for RPFC is proposed for improving the economy and comprehensive carrying capacity of the distribution station area,which includes the RPFC site selection and capacity determination layer and the operation optimization layer.The upper layer is the RPFC site selection and capacity determination layer.This layer obtains typical scenarios based on the scenario reduction method of Kantorovich distance.The optimization goal is to minimize the total investment cost of the distribution station area.At the same time,under the condition of satisfying the RPFC power constraint and capacity constraint,the curr
