The paper proposes a method of tracking the livestock farm load schedule based on the determination of the required generation capacity depending on the actual load schedule. The use of this method allows the management of biogas power plants based on internal combustion engines, depending on changes in the load without power reserve for the time of possible displacement of technological operations. Unlike the power backup method, there is no additional power loss at the time of the reservation, the possible incorrect switches of electrical equipment that do not correspond to the normalized schedule are excluded, there is work in changing the order of operations and the order of switching on the equipment. The use of the method improves the energy efficiency of the biogas plant and also increases the reliability of the livestock farm's autonomous electricity supply system. The calculations of the use of this method for the cattle farm prove its energy efficiency in the conditions of autonomous electricity supply.
Developed approaches to tracking the load schedule of the livestock farm allow for the management of biogas power plants depending on changes in the magnitude of the load without power reserve for the time of possible displacement of technological operations. The use of the proposed method is especially relevant for autonomous power systems. The calculations of using this method for a cattle farm testify to its effectiveness, in particular for a small cattle farm with a herd of 60 valid cows, 11 dry and 29 heads of young animals kept in the winter-stall period, the total saving is 82.8 kW ∙ h day.
