Choice of the Method of Probabilistic Modeling of Statistical Dynamics of Autonomous Power Supply Systems

Abstract

The results of comparative analysis of simulation methods of dynamic modes of autonomous power supply systems are considered. The method of statistical tests, the method of equivalent perturbations, and the interpolation method are discussed. The disadvantages and advantages of these approaches are noted. The problem of the labor-intensiveness of modeling using the methods of statistical tests and the interpolation method is studied using concrete examples. A general conclusion as to the advisability of using the interpolation method is drawn. The mathematical apparatus to be used to calculating the output characteristics is presented. Recommendations are given on the choice of Christoffel numbers and nodes of Chebyshev type for the investigation of the statistical dynamics of autonomous power supply systems.
