Electric Power System from the point of view of model development

In order to conduct the identification of the development of the Electrical Power System (EPS) appropriate numerical data were collected concerning fourteen input variables (ui-ui4) and four output variables (yi-y4) for the period of 1946-2007, with the input variables structure presented in Table 1 and output in Table 2 [2537]. Identification of electrical power system (EPS) for the 30 one-year-long periods for the years 1946-2007, with the step of one year was conducted in the MATLAB environment using System Identification Toolbox [1, 7, 41].
