Calculation of Probabilistic Load Flow in Microgrid Based on Monte Carlo Sampling and Cumulant Method
摘要
Abstract
To improve the calculation accuracy of probabilistic load flow in microgrid,a combination of Monte Carlo simulation and Cumulant method is proposed. First,the liner model of probabilistic load flow is established,then Monte Carlo sampling method and conventional numerical method are used to calculate each cumulant of the probabilistic vari⁃able. Second,the cumulant of the node state variables and branch current is calculated,and it is further resolved by Gram-Charlier expansions. Finally,the probability distribution of cumulant is obtained. A case study shows that com⁃pared with Monte Carlo simulation,the proposed method is reliable and rapid,which can provide reference for electrical dispatching.关键词
