This paper presents a new analytical approach for creation of equivalent aggregate load models applicable to high voltage substations. Such load can functionally replace that distribution network portion which receives its power supply from a given substation. Thus, arbitrary dependent on voltage static load characteristics of the component loads in the middle voltage radial network are considered. The frequency is accepted as invariable. By this analytical technique, based on Jordan elimination, the grid losses are automatically joined to the aggregate load. The calculated aggregate static load characteristics predetermine preservation of the model’s behavior in steady state and transient process. Results of case studies are presented using Eurostag software.
