Abstract
This study presents full transient, three-dimensional numerical models of a PV–TEG hybrid module coupled with single-phase inverter by co-simulation. The influence of factors, such as wind speed, solar radiation intensity, or ambient temperature on the PV–TEG system, was also examined. The numerical model was implemented using Ansys software which accounted the phenomena of Thomson, Seebeck, and Joule’s heat place on the TEG system. Furthermore, its impact on total electrical efficiency was studied. The heat transfer surface of the passive heat sink and forced air circulation positively affected the total heat transfer, and therefore helped to maintain the electrical efficiency at a higher level. Simulation of the single-phase inverter with a PV–TEG system allows the determination of the power characteristics of the system in real time. The results of the study presented may provide a basis for performance optimization of a practical PV–TEG-inverter hybrid system co-design.
Highlights
The vision of the climate neutrality by 2050 presented by the European Commission covers almost all European Union Policy areas and is consistent with the purpose of theParis Agreement, which is to keep the temperature rise well below 2 ◦ C and reduce it to1.5 ◦ C [1]
An illustration of the applicability of a numerical study of photovoltaic systems (PV)–thermoelectric generator (TEG)/heat sink cooled by air flow of a proposed co-simulation with single-phase inverter is given based on the results presented in terms of conversion efficiencies of a PV–TEG module as a function of irradiance, wind speed, and ambient temperature, as well as Seebeck and Joule’s heat effects of TEG’s to observe the influence of each parameter on a hybrid model
The total power generated by the PV–TEG system compared to the stand alone photovoltaic system and generated power increased by 14.3% at STC conditions [2] for a wind speed of
Summary
The vision of the climate neutrality by 2050 presented by the European Commission covers almost all European Union Policy areas and is consistent with the purpose of theParis Agreement, which is to keep the temperature rise well below 2 ◦ C and reduce it to1.5 ◦ C [1]. In order to mitigate the global climate change, an application of novel and economically sound, renewable-based energy resource technologies is crucial [2,3,4]. Solar energy is the most abundant of the renewable energy sources, which all reduce the dependency of energy systems on combustion of fossil fuels, causing photochemical or acidic smog and respiratory diseases [5,6,7]. PV systems may be used as an energy source in industrial plants, transport, and municipal heating systems. It reduces the carbon footprint of these systems contributing to the mitigation of the greenhouse gases emission [8,9,10,11]
