Summary: The research is devoted to solving important tasks of interdisciplinary research work on the topic: «Development of scientific and technical support for energy autonomy of the agro-industrial complex based on environmentally efficient use of agrobiomass for biofuel production», state registration number 0122U000844, implementation of which is planned for 2022–2024 at the expense of the state budget of Ukraine. The main purpose of the planned research is to increase the level of energy independence of agricultural enterprises through renewable energy sources through the use of the principles of dispersed hybrid energy supply, development of energy-efficient and environmentally friendly technologies for growing and processing agrobiomas for biofuel production, as well as modernization of means of control and monitoring of parameters of energy generating equipment. Given the complexity and interdisciplinarity of the planned research, the authors set a task, the solution will be an intermediate stage to achieve the overall goal of research. Such tasks are assessing the potential and identifying promising ways of decentralized power supply of agro-industrial producers based on the analysis of modern technical and technological solutions in the field of electrical engineering and synthesis of promising schemes of combined autonomous power supply of agricultural enterprises. Research of technical and technological prerequisites for the development of a combined system of autonomous energy supply and its components was carried out using the methods of analysis, generalization and systems approach. The potential benefits and effects of the proposed scheme are based on the laws of development of technical and power systems. The technical and technological aspects of the use of wind power generation in combination with solar energy conversion were evaluated. Also, the known methods of accumulating electrical energy received from autonomous electrical installations were analyzed. For efficient generation of electrical energy by modern wind turbines (vertical and ridge), wind speeds from 1.0-1.5 m/s are sufficient, and the nominal operating mode starts at 2-3 m/s, which corresponds to the meteorological indicators of the Vinnitsa region and confirms the possibility use of wind power generation. Also, a scheme was developed for a combined wind-solar autonomous power supply system for small and medium-sized agricultural enterprises and priority areas for further research were formed to improve the efficiency of such a system. At the same time, the most functionally and economically viable option is the use of energy storage systems based on flywheels with partial use of a backup lithium-ion battery pack. A flywheel scheme with a variable dynamic moment of inertia has also been developed, the use of which will improve the maneuverability of the autonomous power supply, and increase its performance.
