Principles of system analysis for sustainable electric power supply to agro-industrial complexes operating in energy isolated territories

The article considers application of principles of system analysis while solving the problems of sustainable electric power supply of agro-industrial complexes operating on energy-insulated territories. The involvement of renewable energy sources in electricity generation is substantiated. The term "regionally isolated electrotechnical complex" is introduced. The principles of the theory of system analysis with regard to a regionally isolated electrotechnical complex - were considered: emergence, optimality and equifinality. It is proposed, when solving the problems of sustainable supply of electricity to agro-industrial complexes operating in energy-isolated territories, to proceed from decomposition approaches to assessing the sustainability of development by integral indicator of levelized cost of electricity LCOER.
