“…The overall energy and exergy efficiencies for the hybrid plant were respectively found to be 66.5 % and 39.7 %, as compared with 64.5 % and 37.6 % with only the biomass part operating, and 27.3 % and 44.3 % with only the solar part operating. Efendiev et al [115] presented several cases operating with solar energy and biogas based systems considered for farms and small holdings in Russia which are at a considerable distance from the local energy networks from economic perspective. Thermal collectors based systems.…”

“…Approximately 95-99% of the generated heat energy would be used to heat housing and livestock buildings for cattle and to support the fermentation processes. About 40-42% of the electricity would be used in cattle buildings for technological processes, and the rest by biogas plants and homes [10].…”

Energy Self-Sufficient Livestock Farm as the Example of Agricultural Hybrid Off-Grid System

et al. 2021

Contemporary agriculture has become very energy-intensive and mainly uses electricity, which is needed for technological processes on livestock farms. Livestock faeces are burdensome for the environment due to the release of methane into the atmosphere. This article presents the concept of a self-sufficient livestock farm as an off-grid energy circuit that is a part of the agricultural process. The key idea is to obtain an energy flow using the concept of a smart valve to achieve a self-sufficient energy process based on a biogas plant, renewable energy sources, and energy storage. During the production process, a livestock farm produces large amounts of waste in the form of grey and black manure. On the one hand, these products are highly harmful to the environment, but on the other, they are valuable input products for another process, i.e., methane production. The methane becomes the fuel for cogeneration generators that produce heat and electricity. Heat and electricity are partly returned to the main farming process and partly used by residents of the area. In this way, a livestock farm and the inhabitants of a village or town can become energy self-sufficient and independent of national grids. The idea described in this paper shows the process of energy production combining a biogas plant, renewable energy sources, and an energy storage unit that enable farmland to become fully self-sufficient through the energy flow between all constituents of the energy cycle being maintained by a smart valve.

“…At present, the equipping of remote and stand alone Arctic objects with autonomous power supply systems became extremely urgent [1][2][3][4] primarily due to economic expediency [5][6][7][8]. In addition, fuel energy sources do not provide energy autonomy due to the fact that they require a constant fuel supply [9][10][11][12][13].…”

The paper presents a research in identification of optimal conditions for friction material operation in the wind turbine braking system. The component composition of friction material includes brass (binder material); steel (fibers); iron oxide (fillers); cuprum, graphite and metal sulphides (friction modifier); aluminum (abrasive). The dependence of its frictional characteristics on the operating temperature is presented. We also presented the simulation of several modes of the wind turbine braking system. The most optimal operation mode for the friction material is the wind turbine rotor braking and its retention for 30 seconds, followed by further retention of the wind turbine rotor for 300 seconds after each 4th braking.The temperature of frictional material with these parameters did not exceed 350 oC, though the minimal idling of wind turbine was provided.
