Construction of Economic Models of Ensuring Ukraine's Energy Resources Economy

The paper presents and formalizes the deterministic economic models of providing Ukrainian economy with energy resources in the conditions of globalization, in particular for electricity and natural gas. It has been found out that the economy of Ukraine is characterized by a shortage of energy resources, which is covered by imports, obsolete and physically depreciated production facilities, imperfect economic and financial mechanisms that determine the low level of use of fuel and energy resources (FER) and energy security. The system of functional models of individual determinants, criteria, components and common indicators of energy security of the Ukrainian economy is considered, which takes into account the influence and interaction between individual hierarchical levels of energy security, for stress testing of critical threats and quantitative and qualitative assessment of the energy security of Ukraine's economy while substantiating and evaluating energy policy measures.
