Full textIn order to improve the performance of a photovoltaic (PV) installation, a complementary approach to improving the efficiency of PV modules is to increase the collection of photons using low concentration of the solar flux on the modules. Flat reflectors are a simple and economical solution for that purpose. They allow increasing electrical production without significant additional cost. However, the estimation of this gain requires careful consideration of the non-uniform illumination provided by these reflectors. The objective of this thesis work is to test the potential of a PV-reflector system with the possibility of periodic adjustment of the tilt angles of the plane of the reflectors and the plane of the PV modules. To this end, it was necessary to set up a PV-reflector demonstrator with industrial modules, as well as to develop a simple modeling tool and validate it experimentally. First, an estimation model of the plane of array, POA, based on Cartesian optics and hypotheses of isotropic radiation of the atmosphere and Lambertian reflection of surfaces is developed. It is based on ground measurements or satellite images inputs. This model experimentally validated allowed to optimize the geometry of a PV-reflector installation by considering a fixed installation or variable geometry, with different periodic adjustments (monthly, seasonal) of the tilt angles of the PV modules and the reflectors, as well as different lengths of reflectors. This strategy for geometrical optimization of POA irradiation has been applied in six locations around the world with very different weather conditions. An analytical estimation photoelectric model is then developed to move from POA irradiance to PV power estimation. Adding flat reflectors introduces a non-uniform distribution of the irradiance on the PV modules which can cause the activation of bypass diodes. This photoelectric model has been tested experimentally for a PV module with non-uniform illumination. Finally, a PV demonstrator is built at the GeePs laboratory (with 6 crystalline Silicon modules connected in series) and equipped with planar reflectors, POA irradiance sensors and temperature sensors. An analysis of power production of this installation was carried out over a year in the absence and presence of reflectors. The analytical model developed previously made it possible to choose the suitable fixed architecture of this demonstrator as well as to conduct performance studies. The results highlight the importance of optimizing the architecture of a PV-reflector system according to the geographic area and the season or the month of the year. They also show that an irradiation study makes it possible to optimize a local potential of such system independently of the technology of the modules, but in no case, it is sufficient to optimize the geometry of an installation. Finally, the theoretical model is simplified: not taking into account the very near horizon, assumption of infinite rows, assumption of a uniform and isotropic atmosphere, constant coefficient of mirrors reflection, pessimistic approach concerning the activation of the bypass diodes… and limited local measurements presenting uncertainties. The installation of demonstrators has made it effectively possible to provide answers and elements of discussion around these aspects

Full textTraffic congestion presents a critical challenge to urban areas, as the volume of vehicles continues to grow faster than the system’s overall capacity. This growth impacts economic activity, environmental sustainability, and overall quality of life. Although strategies for mitigating traffic congestion have seen improvements over the past few decades, many cities still struggle to manage it effectively. While various models have been developed to tackle this issue, existing approaches often fall short in providing real-time, localized predictions that can adapt to complex and dynamic traffic conditions. Most rely on fixed prediction horizons and lack the intelligent infrastructure needed for flexibility. This thesis addresses these gaps by proposing an intelligent, decentralized, infrastructure-based approach for traffic congestion estimation and prediction.We start by studying Traffic Estimation. We examine the possible congestion measures and data sources required for different contexts that may be studied. We establish a three-dimensional relationship between these axes. A rule-based system is developed to assist researchers and traffic operators in recommending the most appropriate congestion measures based on the specific context under study. We then proceed to Traffic Prediction, introducing our DECentralized COngestion esTimation and pRediction model using Intelligent Variable Message Signs (DECOTRIVMS). This infrastructure-based model employs intelligent Variable Message Signs (VMSs) to collect real-time traffic data and provide short-term congestion predictions with variable prediction horizons.We use Graph Attention Networks (GATs) due to their ability to capture complex relationships and handle graph-structured data. They are well-suited for modeling interactions between different road segments. In addition to GATs, we employ online learning methods, specifically, Stochastic Gradient Descent (SGD) and ADAptive GRAdient Descent (ADAGRAD). While these methods have been successfully used in various other domains, their application in traffic congestion prediction remains under-explored. In our thesis, we aim to bridge that gap by exploring their effectiveness within the context of real-time traffic congestion forecasting.Finally, we validate our model’s effectiveness through two case studies conducted in Muscat, Oman, and Rouen, France. A comprehensive comparative analysis is performed, evaluating various prediction techniques, including GATs, Graph Convolutional Networks (GCNs), SGD and ADAGRAD. The achieved results underscore the potential of DECOTRIVMS, demonstrating its potential for accurate and effective traffic congestion prediction across diverse urban contexts

Full textThe integration of PV power generation in a power system reduces fuel consumption and brings environmental benefits. However, the PV power intermittency and fluctuations deteriorate the power supply quality. A solution is proposed by adding energy storages, which are coordinated by a local controller that controls the power flow among all sources and implements an inner energy management. This PV based active generator can generate power references and can provide ancillary services in an electric network. Then micro grid concepts are derived to design a central energy management system of a residential network, which is powered by PV based active generators and a gas micro turbine. A communication network is used to exchange data and power references. An energy management system is developed with different time-scale functions to maximize the use of PV power. An operational daily planning is designed by a determinist algorithm, which uses 24 hour-ahead PV power prediction and load forecasting. Then power references are refreshed each half of an hour by considering the PV power availability and the states of energy storage units. Prediction errors and uncertainties are compensated by primary frequency controllers. Simulation and testing results validate the design of the PV active generator local controller and the central energy management system of the studied residential network

"Exploration of opportunities and challenges brought by Industry 4.0 to the global supply chains and the macroeconomy by integrating Artificial Intelligence and more traditional methods." Electronic Thesis or Diss., université Paris-Saclay, 2021. http://www.theses.fr/2021UPAST037.
Full textIndustry 4.0 is a significant shift and a tremendous challenge for every industrial segment, especially for the manufacturing industry that gave birth to the new industrial revolution. The research first uses literature analysis to sort out the literature, and focuses on the use of “core literature extension method” to enumerate the development direction and application status of different fields, which devotes to showing a leading role for theory and practice of industry 4.0. The research then explores the main trend of multi-tier supply in Industry 4.0 by combining machine learning and traditional methods. Next, the research investigates the relationship of industry 4.0 investment and employment to look into the inter-regional dependence of industry 4.0 so as to present a reasonable clustering based on different criteria and make suggestions and analysis of the global supply chain for enterprises and organizations. Furthermore, our analysis system takes a glance at the macroeconomy. The combination of natural language processing in machine learning to classify research topics and traditional literature review to investigate the multi-tier supply chain significantly improves the study's objectivity and lays a solid foundation for further research. Using complex networks and econometrics to analyze the global supply chain and macroeconomic issues enriches the research methodology at the macro and policy level. This research provides analysis and references to researchers, decision-makers, and companies for their strategic decision-making
Gamez, serna Citlalli. "Towards visual urban scene understanding for autonomous vehicle path tracking using GPS positioning data." Thesis, Bourgogne Franche-Comté, 2019. http://www.theses.fr/2019UBFCA004/document.
Full textThis PhD thesis focuses on developing a path tracking approach based on visual perception and localization in urban environments. The proposed approach comprises two systems. The first one concerns environment perception. This task is carried out using deep learning techniques to automatically extract 2D visual features and use them to learn in order to distinguish the different objects in the driving scenarios. Three deep learning techniques are adopted: semantic segmentation to assign each image pixel to a class, instance segmentation to identify separated instances of the same class and, image classification to further recognize the specific labels of the instances. Here our system segments 15 object classes and performs traffic sign recognition. The second system refers to path tracking. In order to follow a path, the equipped vehicle first travels and records the route with a stereo vision system and a GPS receiver (learning step). The proposed system analyses off-line the GPS path and identifies exactly the locations of dangerous (sharp) curves and speed limits. Later after the vehicle is able to localize itself, the vehicle control module together with our speed negotiation algorithm, takes into account the information extracted and computes the ideal speed to execute. Through experimental results of both systems, we prove that, the first one is capable to detect and recognize precisely objects of interest in urban scenarios, while the path tracking one reduces significantly the lateral errors between the learned and traveled path. We argue that the fusion of both systems will ameliorate the tracking approach for preventing accidents or implementing autonomous driving
