With the development of power systems, their operating conditions become more complicated, as a result of which even small deviations in the operating parameters of electrical networks can develop into severe emergency conditions, leading to disconnection of consumers from the power supply. At oil pumping stations, chemical plants, metallurgy and other industries, synchro-nous motors (SM) with a voltage class of up to 10 kV and a power of up to 30 MW are widely used as drives [6], which is due to their advantages over asynchronous motors [7]. The purpose of the work was to analyze the use of an electrical energy storage system to increase the stability of load nodes.

The article discusses issues related to the development of a model of an electrical receiving device of a 0.22 kV load node in the form of a replacement circuit represented by a linear part and a set of current sources of various frequencies, the parameters of which are described by statistical estimates obtained by the method of parametric identification. A computer has been selected as an electrical receiving device. The simulation results are presented. The resulting model can be used to create a computer model of a 0.22 kV load node.
