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.
