摘　　要：下垂控制元件的不断接入,使电力系统运行情况变得更加复杂,给电力系统分析带来了新的挑战。潮流计算是电力系统分析中最为基础且重要的一类计算。在对具有下垂控制元件的电力系统潮流进行计算时,需要面临常规潮流计算中不曾考虑的新问题。文中从下垂控制的基本原理入手,对计及下垂控制的电力系统潮流计算研究进行综述。首先,简要介绍下垂控制的原理、主要元件类型及下垂控制潮流计算的应用场景;其次,介绍下垂控制元件参与潮流计算时的处理方法;然后,讨论交流系统中计及下垂控制的潮流计算的频率问题,并介绍国内外现有的求解方式;最后,结合电力系统潮流计算新需求,提出计及下垂控制的潮流计算在建模方面需要建立统一化计算模型,在求解算法方面可采用数学规划方法进行求解,但须结合实际场景进一步完善。The access to droop-controlled components makes the operation of the power system more complicated,and also brings new challenges to the power system analysis.Power flow calculation is the most basic and important type of calculation in power system analysis.When performing power flow calculations for power systems with droop control components,it is necessary to consider new problems that are not considered in conventional power flow calculations.The basic theory of droop control is introduced and the research on power flow calculation of power systems with droop control is summarized.Firstly,the principle of droop control,the types of main components,and the application scenarios of power flow calculation with droop control are briefly introduced.Secondly,the processing methods of droop-controlled components in power flow calculation are listed.Then,the questions of alternating current(AC)system power flow calculation with droop control are considered.In addition,the domestic and foreign solutions are also presented.Finally,combined with the new requirements of power flow calculation in power system,it is proposed that the power flow calculation considering droop control needs to establish a unified calculation model in modeling,and the mathematical programming method can be used for the algorithm,but it needs to be further improved according to the actual scene.
