Methodical aspects of the energy industries interconnected operation modeling at the energy security research under modern conditions

The relevance and significance of energy security problems studies in modern conditions of energy systems operation, during the period of negative trends growth in the energy sector, is undeniable and concerns two main aspects: - the need for long-term, deficit-free provision of consumers with the required types of energy resources during the functioning of the energy sector under normal conditions; - the need to create conditions for providing consumers with energy resources when implementing threats to energy security. Due to the impossibility of conducting full-scale experiments on operating fuel and energy systems, work related to the modeling of these systems, the development of specialized software and tools, the rational organization of a computational experiment to find ways to provide consumers with energy-free supplies when operating in normal contingency conditions. The main result presented in the article is a complex of energy systems models that take into account the intellectual nature of modern systems as much as possible and allow conducting energy security studies of the country and regions at a new qualitative level
