Abstract:
Power plants or thermal systems wherein products such as electricity and steam are generated affect the natural environment, as well as human society, through the discharging of wastes. The wastes from such plants may include ashes, flue gases, and hot water streams. The waste cost is of primary importance in plant operation and industrial ecology. Therefore, an appropriate approach for including waste cost in a thermoeconomic analysis is essential. In this study, a method to take waste cost into account in thermoeconomics to determine the production cost of products via thermoeconomic analysi

Abstract:
The establishment of a cost model for complex energy systems based on thermoeconomics can provide technical and economic evaluation indicators for complex energy systems. At the same time, to integrate more renewable energy into the grid, complex energy systems must participate in deep peak shaving. To evaluate the technical-economic performance of complex energy systems involved in deep peak shaving, a novel thermoeconomic cost construction method is proposed based on the production structure diagram, using the gas-steam combined cycle system as an example. these can effectively avoid the der

The exergy analysis, including the calculation of the unit exergetic cost of all flows of the cogeneration plant, was the main purpose of the thermoeconomic analysis of the STAG (STeam And Gas) combined cycle CHP (Combined Heat and Power) plant.

In order to decrease the operation cost of a power plant, a 1000MW coal-fired power plant is studied as the research objective, and an evaluation model about unit thermoeconomic cost is built based on the thermoeconomic theory. By using the Matlab calculation tool, the thermoeconomic optimization of the energy system about the plant is presented. The results show that it is necessary to update the correlated equipment to increase its exergy efficiency in the design of the entry unit. Moreover, the exergy efficiency of the boiler is close to the optimum value, as for the steam turbine, its effi

Abstract:
Most of the thermoeconomic accounting and optimization methods for energy systems are based upon a definition of the productive purpose for each component. On the basis of this definition, a productive structure of the system can be defined in which the interactions among the components are described by their fuel product. The aim of this work is to calculate marginal and average unit costs of the exergy flows starting from their definitions by a direct inspection of the productive structure. As a main result, it is noticed that the only differences between marginal and average unit cost equat

The study explores the possibility of using water (R718) as a refrigerant for a heat pump installation of a heating system.

Abstract Diagnosis of the performance of energy was theoretically developed based on the Structural Theory (Valero, Serra and Lozano, 1993), and traditionally Thermoeconomics have usually been applied to the design of power plants and comparison between alternatives. However, the application of thermoeconomic techniques to actual power plants has always to face the generally poor quality of measurement readings from the standard field instrumentation as an unavoidable first step. The proposed methodology focuses on measurement uncertainty estimation and performance calculation by means of data

Central Solar Heating Plants combined with Seasonal Storage (CSHPSS) systems enable high solar fractions of 50% and more.

Abstract:
In this paper, the combined application of two different approaches to the diagnosis of energy systems is proposed. The first approach is based on thermoeconomic analysis. It consists on the filtration of effects due the dependence of the efficiencies of components on their operating condition. This is obtained through productive models which relate resources and products. With respect to physical models, these are generally less accurate but more compact and thus more suitable to deal with the available measurements in real plants. The second approach is an artificial intelligence (AI) techni

Abstract One of the main problems arising with the thermoeconomic optimization of energy plants, is marginal cost allocation in components containing a flow bifurcation. A typical example is a cogeneration steam turbine. The analysis of the marginal cost allocation of this type of turbine is rigourously studied in this paper. Structural Theory (Valero et al., 1992; 1993) takes under consideration that marginal cost assessment depends on the marginal consumptions of the inlet flow for each outlet energy flow.
