The paper describes non-intrusive load monitoring (NILM) during energy audits of electrical networks of 0.4 - 10 kV consumers. The NILM method allows you to remotely determine the individual parameters of electrical networks and installations of consumers (industrial, municipal, agricultural, etc.). Measurements do not require access to individual installations, which provides a convenient way to collect parameter data compared to placing meters or sensors on each installation. Everything happens similarly to the "black box" method, and the subject of analysis is the total parameters of electricity at the input of the enterprise. Unlike the classic "black box", the structure and internal electrical circuit of the enterprise, passport data and possible operating modes of equipment and electrical networks are known here.

The paper presents a mathematical model for solving the problem of operational optimization and correction of the modes of electric power systems (EPS) in the event of incompatibility of constraints by using the mathematical apparatus of multi-criteria optimization. The incompatibility of constraints is the reason for the impossibility of entering the mode into the admissible region for a given set of parameters of independent variables. The work shows that the use of a multi-criteria model allows a guaranteed solution to be obtained by using additional criteria that allow optimal change of the corresponding independent variables influencing the constraints and to introduce the design modes into the admissible region for their optimization.

The article presents various aspects and data on the digital transformation of the electric power industry of Uzbekistan. The basis of digitalization is a scientific approach that justifies the effectiveness and determines the directions of transformation. The system analysis made it possible to determine the components necessary for the development of digital transformation of electric power systems (EPS). It is proposed to use mathematical multi-criteria methods for formalizing processes and solving problems of digitalization and intellectualization. The transition from traditional to digital electric power industry should be carried out in stages, by forming appropriate clusters at different functional, temporal and hierarchical levels of the EPS, as well as coordination with the digitalization process of other industries.
