Abstract
The research is devoted to the theoretical and practical substantiation of the principles of formation of systems of combined energy supply with heterogeneous sources to increase the energy efficiency of territorial communities in the conditions of climate change resistance. New approaches and structural models for the formation of local microenergy systems are proposed, which will encourage territorial communities to a new type of activity related to their own energy generation based on the use of local types of fuels and renewable energy sources. The principles of building such local energy supply systems, in general, consist in the rational distribution of resources (renewable sources, sources of combined energy generation using biofuels, energy from external networks) and coordination of the processes of generation, transmission, accumulation, distribution and consumption of energy within the boundaries of a separate territorial community by creating its own high-tech infrastructure assets. The formation of the energy balance in the medium and long term is proposed to be carried out on the basis of a resource-process analysis of the operation of local networks by finding the optimal use of local types of biofuels and renewable sources in the combined generation of electricity and heat, taking into account their current value. The cost of energy for the end consumer is determined by differentiated tariffs of energy supply companies and the use of several heterogeneous sources that participate in the process of decentralized energy production. Mathematical relations are obtained for calculating the values of the time intervals of the execution of a set of parallel processes that arise during the interaction of competing sources of distributed generation with end consumers and establishing the regularities of the formation of the energy balance a micro energy system. The proposed method can be a tool for finding optimal energy efficiency management scenarios of facilities with local energy supply, using operational redistribution of energy flows in the system of combined energy generation and forecasting current costs for energy supply in calculation periods. Such a concept can be a theoretical basis for the formation of principles of energy independence of territorial communities. Keywords: territorial community, combined-heat-and-power-system, renewable energy sources, biofuel, energy balances.
