摘要

The global trend of gradual decentralization of energy supply and rapid development of distributed generation is becoming particular relevant for the energy system of Ukraine, which is in a critical state due to the deliberate destruction of energy facilities as a result of military operations. Stable and reliable energy supply at the regional level in order to increase the energy resilience of territorial communities in the face of military threats requires the integration of all available energy sources, renewable and traditional, energy production, storage and supply facilities into the local energy system to provide electricity and heat to a particular region, city or village. The article reviews the recent research on local hybrid systems based on renewable energy sources, including battery energy storage systems. An overview of modern models of energy systems is given, taking into account the rapid development of the concept of distributed multi-generation. To solve the problem of energy supply at the regional level, an approach to modeling energy provisioning based on self-sufficient local energy systems is proposed, an economic-mathematical model of production type is developed to predict the structure and volumes of energy supply, taking into account alternative ways of using renewable energy sources. The model uses the specific structure of technological methods of L.V. Kantorovich and the list of indicators of the product energy balance of the International Energy Agency. A representation of the structure of product and technological links of the energy supply system in the form of a network model has been developed, which allowed to create a single representation of electricity and heat production facilities, mining and enrichment enterprises, and energy consumers. The proposed modeling approach based on the concept of self-sufficiency of local energy systems can be used to determine the most sustainable structure and optimal topology of subsystems based on the predominant use of local energy resources and distributed low-capacity generation to improve the reliability of energy supply in the country as a whole.
