摘要：A method is presented for justifying the construction of a mathematical model of the process of supplying consumers from local sources, taking into account deterministic input information. The target function of the mathematical model is to minimize financial investments in the construction and operation of the local energy supply system using renewable energy sources. Presented activities are aimed at assessing the efficiency of use of fuel and energy resources by local power supply systems, determining the conditions for a positive economic effect, substantiating the composition and main technical parameters of power plants and devices of the local power supply system. At the same time, the conditions of competitiveness of the local power supply system relative to the centralized one should be observed. Sources of local power supply systems should be built on the basis of biogas plants that are capable of producing biogas with long-term storage in gas storages and at the same time are energy storage batteries for other renewable sources. The presented analysis of the energy balance of a biogas plant, taking into account the synergistic effects of interaction between centralized and local energy systems, will make it possible to make optimal decisions for creating a bioenergy complex.
