The paper presents the assumptions and most important features of the mathematical model, along with sample
results of simulation studies that were carried out as part of the analysis and evaluation of the technical and economic structure, which is the installation of a combined heat and power plant before and after expansion with a heat accumulation installation.
The developed mathematical model allowed to reflect the operation of the real system and the considered variants of
integration with the heat accumulation installation in the form of a system of equations and inequalities with the objective function, which is to maximize the profit from the sale of electricity and heat while minimizing the consumption of coal and electricity own needs resulting from the optimization of the operating conditions of individual devices and the dynamic use of the heat accumulation phenomenon. The results presented here come from completed industrial research and development work related to the implementation of a research project aimed at determining the technology that ensures optimal cooperation of a thermal power plant with a highly efficient heat accumulation system.
