Diversification of energy supply to the agricultural sector in the conditions of Uzbekistan

Abstract

At present, the power supply system of the agricultural sector consists only of centralized networks. There are no autonomous-stationary and mobile methods of supply. The current situation of energy consumption in horticulture, such as Beruni district, Karakalpakstan, and further diversification, is analyzed. A systematic approach is applied to the analysis of electrical installations and energy use during agricultural processes, and the corresponding calculation and analytical methods are used to ensure sufficient reliability of the results obtained. The energy balance is compiled in the context of agrotechnical and production processes in fruit and vegetable growing. The issues of central, local, and mobile power supply are studied based on the corresponding energy balance and schedules of electricity consumption. Economic experiments were carried out on a prototype of a mobile power plant “Sun-Wind,” with a capacity of 4.5-4.7 kW·h (in the daytime), 0.8-1.0 kW·h (in the evening). Based on the results obtained, the current and prospective ratios of all three power supply methods are justified. Based on the research results, a system of diversified electricity supply for fruit and vegetable farms was developed and proposed.
