Sustainable integration of Renewable Energy Systems in a Mediterranean island: a case study
2013
Starting from a previous technical and economical feasi-bility study, this paper analyzes the integration of Renewable Energy Sources into an existing territory with specified features of the natu-ral landscape and of the built environment. The work puts into evi-dence that territories development must use suitable tools and rules based on integrated knowledge, since technical feasibility studies do not assess the sustainability of the proposed infrastructures within the built environment and landscape. The studied system is in the is-land of Pantelleria situated between Sicily and northern Africa.
MODELLING, OPTIMIZATION, AND 3E-ANALYSIS OF DISH-STIRLING CONCENTRATING SOLAR POWER SYSTEMS
2022
raggiungimento degli obiettivi del precedente Accordo di Parigi, tutti i Paesi sono stati invitati a impegnarsi a garantire l'azzeramento globale entro la metà del secolo e a mantenere l'aumento della temperatura media globale significativamente al di sotto dei 2 °C, rispetto ai livelli preindustriali, entro il 2050, e più precisamente entro il limite superiore di 1,5 °C. Tutti i Paesi stanno concentrando le loro politiche su una transizione energetica globale che consiste nell'aumento dell'uso di fonti rinnovabili per la generazione di elettricità e nell'uso diretto di calore e biomassa rinnovabili, nell'uso diretto di elettricità pulita nei trasporti e nelle applicazioni termiche, nel mig…
Formation structure of optimality by thermoeconomics: disassembling thermodynamic and external influences in energy systems’ design
2009
In this paper an original thermoeconomic approach for the optimization of complex energy systems is presented, based on a revitalized concept of “scope”, and therefore indicated as Scope Oriented Thermoeconomics (SOT). In plants including dissipative components, it allows to formulate non-arbitrary allocation criteria as concerns marginal costs; consequently, the optimization process is disassembled to recognize the Formation Structure of Optimality, i.e. the specific influences of thermodynamic and economic parameters in the path toward the optimal design. The method is applied to a very didascalic example, that is the optimization of the condensation temperature in a vapour compression ch…
Techno-economic pre-feasibility study of wind and solar electricity generating systems for households in Central Finland
2014
The objective of this work is to investigate the viability of a wind, PV or hybrid wind-PV system supplemented with battery storage for electricity production to meet the electricity consumption of a typical household apartment in Central Finland. The assessment criteria for the analysis were cost of energy and total net present cost of each system configuration. We selected the Hybrid Optimization Model for Electric Renewables (HOMER) software, RETScreen, and PVsyst in our analysis and finally only HOMER was considered for performing system optimization analysis because of the creditability of its results. A PV-battery system is recognized as the most economically feasible option in our si…
