Abstract

The complexity and scale of pipeline energy systems (PES) necessitate the use of multilevel (in terms of structure, problems, and methods) modeling for their analysis, calculation, and optimization, which are based on the theory of hydraulic circuits (THC). This theory was originally proposed at the Melentiev Energy Systems Institute, SB RAS, and since then has been undergoing further development. The use of methodological approaches to multilevel modeling described in this paper allows switching from large systems to hierarchically connected systems of lower dimensionality, that is from complex problems to simpler ones. The use of these approaches for PES analysis and development is illustrated with specific examples. The paper provides the findings of our studies on the municipal heat supply system.
