 The purpose of the work is to create methods and means to promote the development of non-traditional and renewable energy sources in electricity networks, the introduction of which will improve the quality of electricity supply to consumers, reduce electricity losses during transportation and increase reliability. Research methods - generalizing methods of similarity theory and modeling, Markov theory, methods of statistical analysis based on Gaussian mixtures, methods of linear and nonlinear programming are used for analysis and solution of the set problems. Steady-state EM modes were modeled on the basis of the method of nodal voltages. Matrix algebra, graph theory, decomposition and object-oriented analysis are used to describe mathematical models and to form computational algorithms. The provisions of the theory of automatic control and the theory of microprocessor systems have been used to improve the automated control system (ACS). A method for determining the integrated indicator of the quality of electrical networks with RES, which is based on a combination of theories of Markov processes and the theory of similarity and takes into account the reliability of power supply, quality of electricity and cost-effectiveness of its transmission. A method for adjusting power flows in a local electrical system with different types of RES by optimal control of generating power of small hydropower plants is proposed. Algorithms and programs for adjusting power flows taking into account the reliability of SEM by changing the power generation of controlled IDEs have been developed. The structural scheme of ASA has been improved by stations that use RES to coordinate energy supply and consumption schedules.
