Abstract

In the process of developing and creating means of controlling the energy efficiency of technological processes based on electric drives, a task arises related to the modeling of individual electric load schedules of the electric drive. In the analytical study of electricity consumption, the substantiation of the mathematical model of the random process is important. This model, on the one hand, should most adequately reflect the properties of the real process of electricity consumption, and on the other hand, it should allow research of this process using known theoretical methods. A way out should be sought on the basis of compromise solutions regarding the choice of the simplest, but sufficiently accurate models, which will solve the tasks in the most rational way.

 

The probabilistic approach to load estimation allows the most probable description of the process of changing the electrical load over time, given the random nature of this change. The application of this approach should be based on reliable statistical data, which allows to ensure high accuracy of the obtained models. The task consists in simulating random processes of electricity consumption by the main consumer of electrical energy - the electric drive.
