Texto completo da fonteThe standard of living has risen the global energy demand and fossil fuel energy usage is considered the main factor for the rise in global temperature. Renewable energy has been one of the main areas of interest by governments of nearly all countries. Solar energy is clean and the most abundant energy source available around the globe and a photovoltaic thermal (PV-T) system uses solar energy and provides heat and low carbon electricity at the same time. Different heat extraction mediums, hybrid design configurations and the main applications of PV-T collectors are addressed to highlight their feasibility and usefulness. The focus of this thesis work is the modeling, design, optimization, and control of a hybrid PV-T collector. The modeling of the different configurations of hybrid PV-T collectors was conducted and studied in detail. It requires a thorough study of heat transfer between the collector's components and the proposed approach is based on a bond graph technique which is a generic and general tool to represent thermal transfers. A real engineering application, a solar dryer based on the PV-T collector and waste heat recovery along with air recirculation is also investigated. The thesis presents a new design of a PV-T collector that incorporates a storage tank to store heat as well as an electrical resistance to increase thermal production when necessary. Computational fluid dynamics (CFD) simulation of a system and the subsequent validation of the proposed design are then presented. This study also focuses on assessing the influence of internal geometrical parameters. The achieved results permit to analyze the usefulness of the proposed design and validate the viability. Optimization of such systems is highly important in order to get maximum output that is the most energy with lower cost and this requires analyzing the effect of various parameters. The temperature range of the collector must be controlled and the developed models are applied for the purpose of control and observation. The output temperature was controlled using a variety of controllers that are; a simple PI controller, H-infinity controller and sliding mode controller (SMC). Moreover, a multiple model is constructed and an observer is designed for estimating the states of the multiple model. A state observer with an unknown input is also developed, an improvement in the design. It was shown that the designed controllers track the desired set points and the proposed observers estimate the states of the collector, thus displaying the effectiveness. Finally, the hybrid PV-T collector was modeled by using artificial neural network (ANN) and also used for the purpose of control

Texto completo da fonteThe energy requirements worldwide are increasing more and among renewable energy sources, solar energy is exhibiting a very strong growth. Solar hybrid panels that produce both electricity and heat is currently a very promising way. The market for hybrid solar panel with and without concentrator and their characteristics are presented. In the thesis, a hybrid solar panel associated with a holographic concentrator solar radiation is studied. This concentrator separates the visible range used in the photovoltaic cells of the infrared range absorbed by the heat exchanger. The elements of the panel are described. The sensor characteristics and effectiveness depend on the optical and thermal parameters of its elements. These parameters (transmission factors, reflection, absorption, emissivity) were determined experimentally (CERTES IUT Sénart, CEMHTI Orleans, University Blaise Pascal Clermont-Ferrand). The results were obtained in a stationary and dimensional modelling heat exchanges for two different configurations (with two polycarbonate plates with a polycarbonate plate and an air). The model introduces radiative effects, conduction and radiation absorption by volume. The thermal profiles, and electrical and thermal efficiencies obtained show the effectiveness of a hybrid solar collector with holographic concentrator

Texto completo da fonteIn the context of the fight against climate change, the building is a strategic sector to address because of its high consumption of heat and electricity. Solar energy, both thermal and photovoltaic, has strong assets to meet this challenge and is becoming more and more cost-competitive. In particular, the PVT hybrid solar is a promising solution with a double advantage: the extraction of heat under the photovoltaic module brings both a gain in electrical efficiency, and a gain by generating heat for the needs of the building. The state of the art demonstrates the diversity of solar hybrid technologies, and this thesis specifically addresses the unglazed flat-plate design with water as the heat transfer fluid. To address sustainability and performance issues, the company DualSun designed a PVT hybrid module with a stainless steel heat exchanger directly laminated during the photovoltaic module process.The analysis of the DualSun collector is done in Part I, first with a 3D model of the exchanger. This model makes it possible to determine minimum flows, to quantify the interest not to insulate the edges of the module and to visualize that the pressure drop for this concept is mainly related to the inlets and outlets of the module but remains acceptable. Given the limitations in terms of scope and calculation time of this 3D model, simplified models are proposed and compared. The results of these simplified models corroborate a stagnation temperature of the DualSun concept of around 75°C, which confirms that the design is intrinsically resilient to overheating even in the absence of hot water consumption. Finally, thermal performance on 9 prototypes with layer-by-layer composition variations confirm that the model is robust. The models demonstrate that the 250Wp non-insulated version of the PVT panel has a thermal power output of 758 Wth for hot water needs at 30°C.A system analysis of these modules integrated in a complex system is carried out in Part II. For the preheating Domestic Hot Water system (DHW), four software programs, PVSyst, PVGis, Polysun, Solo are compared to Trnsys with the Type 295 and Type 816, which integrate the two simplified models of the module defined in the section I. The physical models of these software programs are consistent with each other in the field of use.The results of these software programs used from statistical data for the weather and consumption habits are compared to field measurements on 28 DHW (domestic hot water) hybrid installations in private homes. The objective was to quantify the errors of estimation of the statistical predictions with respect to the reality. While the standard deviation of PV output and maximum temperatures reached by the modules related to the uncertainty on the weather is low (about 10%), the standard deviation of estimated hot water needs based on an average consumption is much higher (about 30%) because of irregular consumption behavior in individuals in terms of time and volume depending on the days. The average temperatures reached at the level of the modules are higher than 45°C during half of the year and allow an effective preheating of the sanitary tank. Solar covering of hot water needs of 57-58% are measured near Lyon.For combined solar and heat pump (HP+) systems in multi-dwelling buildings and for pool heating (SP) systems, statistical models allow a reliable evaluation of the energy production because of stable hot water needs.In conclusion, solar hybrid should be a key technology for the energy transition of buildings in the coming years. PVT technology will evolve to reduce costs from year to year as observed with photovoltaic technology and thus strengthen its cost-competitive position against gas as a heat source for homes and buildings

Texto completo da fonteThis thesis deals with the control of electrical hybrid system. The main sources consist in an association of photovoltaic and fuel cell system. The secondary sources are a bank of batteries and a bank of supercapacitors. The sizing of secondary sources is realized to manage the power during the transient state and provide extra energy when the power of main sources is insufficient in steady state. The main sources provide the essential energy of the electrical hybrid system during steady state. The control of energy flows and power tracking used in this thesis are based on the flatness technique. This control system allows obtaining high dynamic properties in the power tracking and the regulation of system. The supervisor for sharing the power between the different storage devices is realized thanks to a fuzzy logic controller. This controller ensures that the bank of supercapacitors with its interface converter is used as a power filter and provides the energy in transient states. However, the bank of batteries provides or absorbs the energy in longer periods especially during recovery or overload modes
