Fault Ride-through Control Parameters Identification Method for Energy Storage Power Conversion System Based on Morris Sensitivity Analysis
摘要
Abstract
For improving the accuracy of ault ride-through(FRT)control parameters of power conversion system and enhancing the accuracy of simulation analysis,a FRT control parameter identification method based on Morris sensitivity analysis is proposed.First,a hardware-in-the-loop simulation platform for the power conversion system is set up using RT-LAB,and FRT operation conditions under different fault conditions are used as the identification data set.Then,the Morris method is used to analyze the sensitivity of the parameters to be identified under each con-trol mode,providing a theoretical basis for the stepwise strategy.Finally,the cuckoo search algorithm is improved by combining dynamic parameters and dynamic step size strategies,and the identification of high-sensitivity and low-sensitivity FRT control parameters is completed in sequence.The simulation results show that compared with the CS algorithm,the average parameter error of the proposed dynamic CS algorithm is reduced by up to 15%,the si-multion accuracy is effectively improved and the optimization efficiency is increased by more than 40%.关键词
