Hybrid Power Supply Using Renewable Energy Sources

Abstract
The work has determined the possibility of full coverage of the needs for electricity of enterprises under the conditions of joint use of a biogas plant and solar panels on the example of a livestock farm. It has been established that the use of renewable energy sources has a significant potential for growth, in particular, the generation of electricity by a biogas power plant, calculated according to the minimum indicators for a cattle farm, provides more than 50% of the required electricity, in addition, there is also thermal energy that is used to heat the farm. The use of biogas obtained from the waste of a cattle farm and together with solar panels makes it possible to cover the need for electricity with a significant reserve. It has been established that the electrical power of a biogas plant, which works in conjunction with solar panels, should be at least the average value of the power consumption to provide power to the consumers of the livestock farm, especially in the winter months when insolation is minimal. The use of hybrid renewable energy sources based on biogas plants and solar panels makes it possible to significantly increase the efficiency of energy use, subject to the introduction of means for regulating the output of the biogas plant. The developed approaches to tracking the load schedule of a livestock farm that allow for the management of biogas power plants depending on changes in the load with energy storage units, which are needed at the time of starting and synchronizing the biogas plant generators. The use of the proposed method for tracking the load schedule is especially relevant for autonomous power supply systems, since it allows more efficient use of energy resources, in addition, this approach can significantly reduce the storage capacity and form a gas supply. A comparative analysis of the energy balance for daily power supply with various methods of using hybrid renewable energy sources showed the best energy performance when regulating the power of a biogas plant based on monitoring the load curve.
