Variance Analysis Method for Simulation Model Dynamic Consistency Base on Hilbert-Huang Transform

With respect to the nonlinear and nonstationary of dynamic simulation model data, the methods that can extract validation metric and guide model modification are the challenges faced by simulation dynamic validation. The variance analysis method for simulation model dynamic consistency based on Hilbert-Huang transform (HHT) is proposed in this paper. Firstly, taking the time-frequency distribution of dynamic data obtained by HHT as validation metric, the dynamic consistency test model based on variance analysis is built up. And then, the quantitative validation of simulation model and the location of error source are achieved by variance analysis. Finally, simulation and case study show the practicability and feasibility of this method in the validation of dynamic consistency and the localization of error source.
