摘要
针对电力系统运行中存在的大量不确定因素,探讨概率最优潮流方法及其在无功优化配置中的应用。分析和比较了蒙特卡罗法、半不变量法、点估计法等几类主要概率分析方法及特点,重点介绍点估计法及应用。给出了概率无功优化模型及蒙特卡罗法、半不变量法和点估计法的求解方法,通过实例对各种算法的准确性进行比较,并验证了方法的有效性。
In the power system planning and operation,there are lots of uncertain factors.This paper discusses the probabilistic optimal power flow method and its application in optimum reactive power allocation.Through the analysis and comparison of the main kinds of probabilistic analysis methods and their characteristics including the method of monte-carlo,half invariable,point estimate,the paper focuses on the point estimation method and its application.The probabilistic reactive power optimization model and the solution methods of monte-carlo,half invariable,and point estimation are given.By a case study,the accuracies of these methods are compared,and the validities are demonstrated.
