Development of an optimization model to find the most efficient source of thermal energy in order to achieve sustainability

This article analyzes the current state of the Russian thermal power complex, identifies existing problems in the industry, and proposes measures to improve its sustainable operation and development. The purpose of this study is to assess the current state of the Russian thermal power complex and develop measures to ensure its sustainable operation and development.

A theoretical analysis of scientific papers revealed that researchers are concluding that it is necessary to improve the efficiency of the thermal power industry and are proposing various approaches to addressing this issue. An analytical analysis revealed that production equipment is not being utilized to its full capacity, and, consequently, organizations are unable to cover the costs associated with modernization and capacity upgrades. The study analyzed the relationship between investment volumes and the number of accidents, con-cluding that increased investment does not significantly reduce the number of accidents. Based on the empirical study, factors influencing sustainable operation and development were identified.

The study proposed an optimization model for finding the most efficient thermal energy source, which presented an objective function and identified constraints. The study drew the following conclusions.
