The agro-industrial complex is one of the most stable in terms of revenue to the budget of intersectoral formations, in which significant amounts of electricity produced using fossil fuels, mainly imported, fuel resources are consumed for the implementation of production processes, which poses a threat to its effective functioning and makes in the research article. The purpose of the article is to assess the potential and determine promising methods of decentralized power supply for agro-industrial producers based on the analysis of modern technical and technological solutions in the field of electrical engineering and the synthesis of a promising scheme for a combined autonomous power supply system for agricultural enterprises.
The article assessed the technical and technological capabilities for the use of autonomous electrical installations by small and medium-sized enterprises of the agricultural sector, operating on the principle of conversion of renewable sources, taking into account the natural and climatic potential of the Vinnytsia region.
As a result of a comparative analysis of the operational characteristics of the known methods of accumulating electric energy, it was found that in the conditions of autonomous power supply of small and medium-sized agro-industrial enterprises due to the conversion of alternative energy sources, the most functionally and economically justified option is the use of energy storage systems based on flywheels with partial use of a backup unit lithium-ion batteries.
Based on domestic and foreign experience, a promising scheme of a combined autonomous power supply system for small and medium agricultural enterprises was proposed and priority areas for further research were formed to improve the efficiency of such a system.
The study of technical and technological prerequisites for the development of a combined system of autonomous power supply and its components was carried out using methods of analysis, generalization and a systematic approach. The potential advantages and effect of the proposed scheme implementation are based on the laws of development of technical and electric power systems.
