Comparison analysis for validating methods of system simulation models

The credibility of system simulation models has a direct influence on its reliability, security and combination property, and dynamic consistency test of validating simulation models is a hotspot and difficulty in the fields of system simulation. According to the results of comparison analysis of three main test methods, namely Theil's Inequality Coefficient method (TIC), spectrum analysis method and distance test method, it can be concluded that distance test method can realize quantitative test and has no limitation for test data in the time domain, and reach a high credibility of test results. At the same time, the comparison conclusion is beneficial to choosing rational methods for concrete simulation results and giving advices for forming national standards in the future.
