"Modélisation et analyse du flux collecté par une centrale solaire à tour dans une atmosphère réaliste : couplage centrale solaire - atmosphère dans un code de transfert radiatif Monte-Carlo". Electronic Thesis or Diss., Université de Lille (2018-2021), 2021. http://www.theses.fr/2021LILUR015.
The flux collected by the receiver of a solar tower plant is traditionally estimated by the only consideration of the direct solar radiation reflected by the heliostat field. In this thesis, we propose the development of a new version of an atmospheric radiative transfer code to consider not only the flux from direct solar radiation reflected by heliostats but also all the other contributions as the scattered solar radiation, the solar radiation reflected by the ground, on so on. To perform that, the Monte-Carlo atmospheric radiative transfer code SMART-G is chosen and developed to allow the incorporation of a solar tower plant in a realistic atmosphere. The method to create this new tool is completely described and validated. The use of this new tool has proved to be essential for a correct estimate of the flux collected by a solar tower plant located in a desert. An first analysis of the environnemental gain is realized for the annually collected flux of the PS10 solar tower plant, placed in Ouarzazate in Maroc

Compare to fossil fuel energy resources, solar energy presents the inherent characteristic given by the very nature of the resource (intermittent availability). This observation highlights the need for thermal energy storage system. This doctoral thesis studies thermal energy storage for concentrating solar power plant, as well as its two essential components: the heat transfer fluid and the thermal energy storage materials. The analysis of the thermocline storage system with filler materials is achieved through experimental and numerical approaches. An innovative alternative for the heat transfer fluid consists to use vegetable oils, which offers comparable thermal properties and operating behavior to conventional thermal fluid. Regarding thermal energy storage materials, many natural and recycled materials can be used. A storage material with controlled geometry is developed from steel industry co-product. The originality of this combination for thermal energy storage combines performance, materials availability at industrial scale while reducing environmental and financial impact

Convinced of the interest and potential of natural materials and industrial waste, this thesis has contributed to the development of heat storage materials (TESM) for CSPs in West Africa. More specifically, this research focused on the valorization of laterite from Burkina Faso, the bottom ashes from the coal-fired power plants of SONICHAR in Niger, residues of calcium carbonate (lime) from the acetylene in Burkina Faso and the vegetable oil of Jatropha curcas from the company Belwet in Burkina Faso. The results of this study showed that Jatropha curcas oil can be considered as a viable alternative to conventional HTF and TESM for CSP operating at 210 °C. The materials elaborated from bottom ashes and laterites present a refractory character due to the presence of mullite and spinel. The addition of lime makes it possible to reduce the melting temperature while preserving the refractory and conductive character of the obtained phases. Due to their stabilities, and the absence of conflict of use, the obtained materials can be used as TESM in CSP at temperatures up to 900 °C

Industrial concentrated solar power plants consume 4 m3/MWh of water to cool down their thermodynamic cycle. In arid area, it could induce conflicts of use on a more fundamental resource than electricity. This fact highlights the need to develop alternatives dry cooling technologies but equally effective. The solar field represents 50% of the investment cost of a CSP plant to be used only daily for the heat production needed for the thermodynamic cycle. The approach of the project is to use this huge area as macro-heat exchanger with its surrounding environment through a coupled heat transfer with the ambient air (convective) and with outer space at 3K (radiative). After validating the compatibility of solar field materials for a such application, these research works has shown experimentally that in addition to extract the waste heat of the thermodynamic cycle, it could also produce cold by night radiative cooling. An innovative alternative solution for cooling CSP plants offering two new features to their already existing solar field for the benefit of its paying off

Since the early 40's, world energy consumption has grown steadly. While this energy mainly came from fossil fuel, its use has included an increase in temperatures. It has become urgent to reduce greenhouse gas emissions to halt climate change. In this context, the development of concentrated solar power (CSP) is a promising solution. The scientific community related to this topic has to focus on efficiency enhancement and economic competitiveness of CSP technologies. To this end, this thesis aims at providing an optimal design method applied to central receiver power plants. It takes advantage of methods developed over many years by the research group StaRWest. Both RAPSODEE (Albi), LAPLACE (Toulouse) and PROMES (Odeillo) researchers take an active part in this group. Coupling high performance Monte Carlo algorithms and stochastic optimization methods, the code we developed allows an optimal design of concentrated solar systems. This code is used to highlight the potential of an uncommon type of central receiver plants: reflective towers, also called "beam down" central receiver systems

Solar thermal power plants use large and expensive solar fields to collect solar energy, the performance of which can still be improved. Faced with this situation, this thesis explores multiple pathways to improve performance and if possible reduce cost of the three types of surfaces encountered in solar collectors: reflectors, antireflective windows, selective absorbers. For this purpose, we have developed a simulation and optimization (stochastic algorithm) program, to study and maximize solar performance of the thin films ensuring the three functions of solar collectors. We have identified several solutions which combine high performance, scarce use of rare materials and durability. To reach the full potential of all identified solutions, we have conducted advance multi- criteria analysis, by studying the impact of collector geometry, local atmosphericconditions and problematics related to material selection and surface fabrication (roughness, thickness and composition errors)

Large scale solar systems at low and medium temperature (80-120 °C) can provide renewable and competititve energy to district heating and industrial processes. These systems, which are capital-intensive and have low operating costs, present a long-term return on investment. Automated monitoring and fault detection and diagnosis are key elements to guarantee optimal performances during all the lifespan of the plant.This dissertation aims to analyze of the main faults, in a detection and diagnosis purpose. First, an exhaustive study of the dysfunctions that can affect the large scale solar systems enabled to identify the more frequent and serious faults, also called critical faults. Among these critical faults, six were selected for a more detailed study.To analyze the behavior of the system subjected to the studied faults, a numerical model was implemented. A new flat plate thermal solar collector model was particularly developed as existing ones do not detail enough several physical characteristics required for the reproduction of faults. An experimental validation of this model in normal and faulty operation showed that it enables a simple fault modelling and presents a realistic behavior.A methodology to numerically analyze the impact of the faults on the system behavior is then proposed. A set of features enabling the characterizing of this behavior are particularly defined. This approach is applied first at the scale of directly affected component then at system scale. The results enable to identify detectable and isolable faults, but also to propose a reduced set of features sufficient to properly detect and diagnose them.This work presents a methodologic base and first results to develop an automated algorithm for detection and diagnosis of critical faults of a large scale thermal solar system

This PhD thesis is about the study of two-phase flow patterns evolution during progressive evaporation in horizontal tubes. The goal is to better understand the flow regimes inside a receiver tube of a concentrated solar power plant with direct steam generation. This technological evolution allows vapor production directly inside the solar field, which can lead to coast reductions. A two-phase liquid-vapor flow occurs inside the tube, which is currently still difficult to predict. Numerical simulation is an interesting way to investigate these complex phenomena. A model has been developed in order to simulate the flow patterns, from first vapor generation to large vapor slugs. It is based on Fluent software's two-phase VOF model, to which are added user-defined functions and a new dispersed phase. Different phenomena linked to the evaporating process are taken into account: vapor creation at the wall, its transport, recondensation and large structures creation. The model is used to simulate evaporating flows, and retrieves well two-phase flow patterns evolution. Validation is made using experimental data from the literature, by comparing flow regimes obtained for different flow rates and heat fluxes. Finally numerical simulation of direct steam generation inside a concentrated solar plant receiver is conducted, clearly showing apparition and evolution of two-phase flow patterns. Because few experimental data where found in the literature concerning evaporating two-phase flows visualization, a new experimental apparatus has been conceived and sized in order to better validate our numerical results

Direct steam generation concentrated solar power plants use the optical concentration of solar direct irradiation to generate high pressure and high temperature steam in the absorber tubes. Steam is used as the working fluid of a Rankine-type thermodynamic cycle for the propelling of a steam turbine and an electric generator. The conjunction of the natural transient condition of solar irradiation and the presence of a two-phase flow inside the absorber tubes leads to a strong dynamic behavior of the steam generation system. Moreover, steam turbines being very sensitive to inlet temperature transients, the control of steam generation has to be achieved with the best possible efficiency. Because of the large time constants of the flow in the solar field (among other reasons), basic control strategies are poorly efficient and not well suited. The aim of this thesis work is the study, through modeling and simulation, of the dynamic behavior of the steam generation system. Dynamic modeling of linear Fresnel and parabolic-trough solar plants is carried out, and experimental data from a parabolic-trough prototype are used for validation. The models are used for the study of advanced control strategies, for a better control of steam conditions at the solar field outlet, under irradiation transients. Short-term irradiation prediction methods are evaluated for a use in the control strategies
