Allocation of economic costs in trigeneration systems at variable load conditions including renewable energy sources and thermal energy storage 2018 Access copy available to the general public Unrestricted As energy systems become more and more complex, the issue of the appropriate way to allocate the cost of the resources consumed increases because the way in which allocation is made directly affects the prices of the products obtained and, thus, the consumers’ behavior. Thermoeconomics has been used to explain the cost formation process in complex energy systems. The thermoeconomic analysis of a trigeneration system including renewable energy sources (RES) and thermal energy storage (TES) was developed to determine the energy, capital, and total unit costs of the internal flows and final products. This work addresses issues not yet deeply studied in thermoeconomics, namely the joint production of energy services in dynamic energy systems and the incorporation of TES, RES (photovoltaic panels) and a component with different products for each operation mode (heat pump producing heat in heating mode and cooling in cooling mode). The interconnection between charging and discharging periods through the TES units was explored, allowing the discharged flow to be traced back to its production period. The trigeneration system resulted more profitable than the reference system, with total cost savings of 9942 €/yr, which was translated into the lower annual total unit costs of the final products. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/ES/MICINN/ENE2014-57262-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.537 2018 THERMODYNAMICS 3 / 60 = 0.05 2018 Q1 T1 ENERGY & FUELS 15 / 103 = 0.146 2018 Q1 T1 2.048 2018 Building and Construction 2018 Q1 Civil and Structural Engineering 2018 Q1 Electrical and Electronic Engineering 2018 Q1 Pollution 2018 Q1 Industrial and Manufacturing Engineering 2018 Q1 Mechanical Engineering 2018 Q1 Energy (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4411-9834 Lozano, M.A. Universidad de Zaragoza (orcid)0000-0002-5161-7209 Serra, L.M.
