电压暂降随机预估的非序贯蒙特卡罗方法研究
Research on Random Estimation of Voltage Sags Based on Nonsequential Monte Carlo Method
摘要
Abstract
Since Monte Carlo method suffers from low computation efficiency and long time consumption in the random estimation of voltage sags,this paper presents a random estimation method based on nonsequential Monte Carlo meth⁃od. A mathematical model of state variables in the fault of voltage sags is built,and an IEEE 9-node test system model is established in Matlab/Simulink,which obtains the state variables of the fault model. The probability distribution of the amplitude of voltage sags is analyzed,and the indices of voltage sags are simulated by nonsequential Monte Carlo and Monte Carlo methods respectively. The results of the IEEE 9-node test system show that compared with Monte Carlo method,the proposed method improves the convergence,computation speed and stability obviously.关键词
