Method for scientific substantiation of agrarian complex energy system using local resources

Problem of creating agricultural energy systems is of a significant multifactor system-and-situational na­ture, depending on the external economic and energy situation in the country, which predetermines accelerated development of autonomous energy centers of agro-towns based on joint use of centralized fuel and energy and local energy resources. The modern method for integrated energy supply of agro-towns as integrated territorial-and-economic entities of agro-industrial complex of the country with significant technical potential of local resources, including renewable energy sources, was devel­oped based on appropriate conceptual tools and principles of multi-level conceptual design and simulation modeling of inte­grated energy systems using method of conceptual expertize as advanced scientific research, pre-project technical-and-eco- nomic and technical -and-technological substantiation of rational structure of the concept project. As a priority, a system­atic approach to development of regional systems of pilot projects of demonstration areas of high energy efficiency based on highly organized agro-towns and, first of all, experimental farms of the National Academy of Sciences of Belarus is substantiated. With this purpose, the Institute of Energy of the National Academy of Sciences of Belarus has developed software-based computing complex of an intelligent multi-level decision making support system providing simulation mod­eling and substantiation of rational scenarios for the concept project of an integrated energy system. The software package includes system of inherited and original software packages for staged procedure for performing computational experiments with a reasonable range of research risks. The conceptual content of the project depends on the Customer’s requirements, aims and objectives of the research, sectoral focus of agro-industrial enterprise, availability of sufficient technical poten­tial of local energy resources, and the consistency of interests of the owners, regional and national governing structures of various sectors of an agro-town. The studies performed with examples of a number of agro-industrial enterprises and social and cultural sectors of agro-towns show a significant (up to 60%) improvement in quality of choosing a rational struc­ture of a concept project for an integrated energy system and reduction (203 times) in sophistication of engineering design compared to ordinary 2-3-variant technical-and-economic substantiation of the project.
