Purpose. Analysis of the problem of energy efficiency and electromagnetic compatibility of powerful energy associations with nonlinear loads and renewable energy sources. Finding promising ways to increase energy efficiency of power supply systems.Methodology. Mathematical modeling of electromagnetic compatibility.Findings. The analysis of the problem of energy efficiency and electromagnetic compatibility of powerful energy associations with nonlinear loads and renewable energy sources allows us to formulate the following provisions that determine the objectives of this study. A promising way to increase the energy efficiency of power supply systems is the introduction of refined methods of analysis and forecasting of electrical modes of industrial enterprises, as well as indicators of voltage quality and reliability of electrical equipment.Originality. Although the problem of electromagnetic compatibility has been the subject of numerous domestic and foreign studies, it should be noted that most of these works consider the processes of generating electromagnetic interference in the electrical network without reference to the technological schedules of electrical equipment.Practical value. One of the electromagnetic effects, which is manifested in the operation of frequency converters, are significant levels of interharmonics and higher harmonics, which are generated in the electrical network and contribute to the growth of electricity losses and reduce the service life of electrical equipment. However, the regularities connecting the parameters of the power system and the modes of powerful industrial converters have not been studied, and the substantiation of the parameters of a rational energy efficient mode of the power supply system, taking into account individual graphs of higher harmonics, has not been carried out until today.
