Abstract
The paper presents the main provisions of the methodology for identifying vulnerable elements in the fuel and energy complex, which is studied as a set of industry critical energy infrastructures. This methodology is based on the use of industry models system in the fuel and energy sector, on the analysis of the interconnected critical energy infrastructure's work in normal functioning and during emergency situations. The paper proposes a schematic diagram for the formation of vulnerable elements list for fuel and energy complex based on critical elements of industries. The scheme of work with a two-level system of models is given. The results of testing the methodology and developed models are presented (illustrative example).
Highlights
The paper presents the main provisions of the methodology for identifying vulnerable elements in the fuel and energy complex, which is studied as a set of industry critical energy infrastructures
Critical infrastructures in accordance with the definitions [1, 2] with full confidence include industry energy systems and the fuel and energy complex (FEC), which is an interconnected infrastructure consisting of separate energy systems
This statement is confirmed by the importance of these infrastructures for the country's economy, supported by the need to ensure energy security, characterized as the state of protection of citizens, society, the state and the economy from threats of deficit in meeting their needs for energy resources of acceptable quality, from threats to disruption of uninterrupted energy supply
Summary
Studies to identify the most vulnerable elements (objects) of interconnected critical energy infrastructures (energy systems) are carried out on the basis of optimization of territorial-production models of functioning of the country's fuel and energy complex. To assess the criticality of the fuel and energy complex object in the framework of optimization calculations, the element significance criterion is used, which characterizes the relative changes in the analyzed model parameters when the functioning mode of this object changes over the entire set of states. This indicator is given by formulas (1): ZOi = ∑Jj=1 ZOij ∗ ZCj (1). A list of critical elements for the fuel and energy complex is formed
