Guidelines to developing software for thermoeconomic analysis of energy systems. Part II: Application to thermoeconomic diagnosis

Abstract:

The aim of this second part of the paper is to show the capabilities of the ther-moeconomic analysis to the diagnosis of energy systems. A collection of algorithms for the analysis of the cost formation process of products and residues is presented. They use the FP table, a mathematical representation of the thermoeconomic model discussed in the first part of the paper, as input data. These results are applied to the thermoeconomic diagnosis of energy systems. Thermoeconomic diagnosis is performed by comparing two states of the system a current state that one wants to analyze and a reference state with which one wants to compare with. The algorithms to compute the impact of the malfunctions in terms of additional resources consumption and the analysis of the causes of the increase of irreversibilities and residues are described.
