Increasing power supply efficiency of livestock complexes at small farms using renewable energy sources

Abstract

The paper provides technical recommendations for designing power supply systems for livestock complexes of small farms based on renewable sources of electric energy. Resource analysis of solar and wind energy on the Russian Federation territory shows that the use of the hybrid solar-wind power plants is most appropriate. In the case, it is advisable to use batteries and diesel generators to ensure reliable and uninterrupted power supply. Herein is offered a version of making up a structural diagram of power supply system for a small farm with combined power supply from centralized power grids and renewable energy sources. It is shown that the use of such a system can significantly save due to the power not consumed from the grid, and also allows selling excess energy to the power system. Herein is offered a version of building up a structural diagram of an autonomous power supply system based on a hybrid solar-wind power plant and a diesel generator for those regions, where there is no distributive electrical network. A design of a vortex wind power installation has been developed for practical use as part of the considered options for power supply schemes, which allows using small winds and low-potential thermal upward flows, reducing low-frequency vibration and noise, placing it on the top of industrial buildings with ease of installation, maintenance and repair.

Self-generated power supply of agricultural enterprises based on renewable energy sources

“…The station diagram is shown in Fig. 2 [10][11][12][13]. The basic principle of such SGPSS constructing consists in maximum possible application of wind and solar energy and minimum application of the energy produced by DEPP.…”

Reduction of Defective Conditions of the Wind Power Plant Operation at Reserving the Operation Modes of Alternative Energy

“…Each has its unique requirements; for example, the system reliability may be a more valuable property than the cost of energy for systems managed automatically (Deltenre and Runacres, 2019;Fernández-Guillamón et al, 2019;Rabanal et al, 2019). While consumers in industrialized areas expect high levels of energy quality, suitability, and competitiveness, ease of maintenance is a critical factor for the consumers in the countries that are in the process of development (Tsgoev, 2012;Dekkiche et al, 2017;Rudenko et al, 2019).…”
