A Review of Linearization Methods for AC Power Flow in Power Systems
摘要
Abstract
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.关键词
