摘　　要：电力系统潮流方程具有显著的非线性特性,针对大规模电力系统的潮流计算易出现计算结果不收敛的现象。近年来,国内外文献涌现出大量适用于电力系统交流潮流计算的线性化潮流模型,但缺乏对经典线性化潮流模型分离变量过程的系统性梳理与总结以及对经典线性化潮流模型计算性能的数值比较。首先梳理了目前电力系统经典线性化潮流模型的主要思路,对各种线性化潮流模型分离变量的过程进行分析与总结。然后对比了线性化潮流模型的相同性及其在输电网和配电网应用上的差异,并从计算误差、计算时间和灵敏度等方面对比了各线性化潮流模型的性能。最后根据每一种线性化潮流模型的优缺点,对各线性化潮流模型的适用场景进行了总结及展望。Power system power flow equations exhibit significant nonlinear characteristics,and non-convergence is common in large-scale power system calculations.Recently,numerous linearized power flow models for AC power flow calculations in power systems have been proposed globally.However,a systematic compilation and summary of the variable separation process in classical linearized power flow models,along with numerical comparisons of their computational performance,are lacking in the literature.In this paper,the key concepts of existing classical linearized power flow models are organized for power systems,and then the variable separation process in these models is analyzed and summarized.Subsequently,the similarities and differences of linearized power flow models are compared in transmission and distribution network applications.Next,the performance of each linearized power flow model is evaluated in terms of computational error,computation time,and sensitivity.Finally,the applicable scenarios of each linearized power flow model is summarized based on their advantages and disadvantages.
