Les véhicules électriques hybrides (VEH) sont une alternative intéressante, notamment en milieu urbain. Cependant, la conception de tels systèmes est complexe car la chaîne de traction (composants et architecture), la mission et la gestion énergétique du véhicule sont intimement liées.Les travaux de V. Reinbold ont permis de mettre au point une méthodologie de dimensionnement de VEH. Les composants sont optimisés conjointement avec la gestion énergétique sur un cycle de fonctionnement afin de minimiser la consommation de carburant du véhicule. Une attention particulière est portée à la conception fine de la machine électrique via un modèle électromagnétique adapté à l'optimisation.Dans la suite de ces travaux, nous approfondissons plusieurs aspects du dimensionnement des VEH. Tout d'abord, nous introduisons la possibilité de gérer des paramètres discrets de la machine, comme le nombre de paires de pôles. Dans un second temps, nous développons un modèle thermique de la machine prenant notamment en compte les échanges autour des têtes de bobine. Ce modèle analytique par réseau de résistances thermiques est intégré puis utilisé dans le processus de dimensionnement par optimisation. Il a été préalablement validé via un modèle par éléments finis. Des méthodes d'analyse d'incertitude et de sensibilité sont appliquées afin de quantifier l'influence de certains paramètres thermiques. Enfin, nous appliquons la méthodologie de dimensionnement par optimisation à une architecture série/parallèle, intégrant deux machines électriques.

Book excerpt: Depuis l'essor des ordinateurs et des capacités de calcul, la conception des composants du génie électrique repose largement sur des simulations informatiques et sur des calculs numériques. Dans les systèmes complexes, où de nombreux composants interagissent pour le bon fonctionnement du système, le dimensionnement optimal du composant dépend nécessairement de son environnement systémique. La conception de celui-ci est fortement liée au fonctionnement du système global. La conception intégré du composant dans son environnement systémique permet ainsi de repousser les limites de l'efficacité énergétique, pour des systèmes plus performants et moins consommateurs. En support à ce contexte méthodologique, nous proposons de dimensionner par optimisation un moteur électrique pour un véhicule hybride dans le but d'améliorer l'efficacité énergétique globale du véhicule. Dans ce travail, nous avons modélisé le moteur électrique par un schéma réluctant, et nous proposons deux approches méthodologiques différentes du même problème. Les points clés de notre approches sont : la prise en compte de l'environnement du moteur, du cycle de fonctionnement et de la gestion de l'énergie du système.

Book excerpt: L'hybridation des sources de puissance dans le domaine des applications embarquées s'est imposée comme une solution adéquate pour répondre aux législations environnementales et atteindre une meilleure efficacité énergétique. Toutefois, le choix dans le dimensionnement des composants et la stratégie de commande doivent répondre à un cahier des charges, souvent complexe et hétérogène, tout en limitant les coûts du système. La résolution de ce problème d'optimisation incluant de nombreuses variables peut s'avérer complexe à cause des non-linéarités présentes dans le problème formulé. Il faut donc disposer d'outils de résolution efficaces et capables de fournir une solution fiable. Dans cette thèse, nous proposons une méthode d'optimisation globale pour le dimensionnement et la commande optimale de véhicules hybrides basée sur l'optimisation combinatoire, et en particulier sur la programmation linéaire en nombres entiers (PLNE). A partir d'un problème d'optimisation non linéaire, le problème initial est reformulé en une multitude de sous-problèmes linéaires en nombres entiers sur lesquels un algorithme de Branch & Bound parallèle est exécuté. Afin de résoudre des problèmes de grande taille, un second algorithme basé sur le Branch & Cut est développé. Cette méthode est déployée pour l'étude d'un système d'alimentation hybride d'une mini-excavatrice électrique. Le problème d'optimisation, dans lequel des contraintes énergétiques et des contraintes de vieillissement sont implantées, est évalué suivant différents paramètres du cahier des charges. Enfin, cette approche est également appliquée pour l'optimisation de trajectoires d'un système multi-actionneur synchronisés.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the methods of storage commonly used in hybrid systems. After an introductory chapter reviewing the basics of electrochemistry, Chapter 2 is given over to the storage of electricity in the form of hydrogen. Once hydrogen has been made, we have to be able to convert it back into electricity on demand. This can be done with another energy converter: a fuel cell, the subject of Chapter 3. Such a system is unable to deliver significant dynamics in terms of storage and release of electricity and needs to be supplemented with another solution: a detailed study of supercapacitors is provided in Chapter 4.While the storage systems touched upon in the previous three chapters (hydrogen batteries and supercapacitors) both exhibit advantageous characteristics, at present they are still relatively costly. Thus, the days of the electrochemical accumulator by no means appear to be numbered just yet. This will therefore be the topic of Chapter 5. Finally, on the basis of the elements laid down in the previous chapters, Chapter 6 will focus on electrical hybridization of these storage systems, with a view to enhancing the performance (in terms of energy, lifetime, cost, etc.) of the newly formed system. Aimed at an audience of researchers, industrialists, academics, teachers and students, many exercises, along with corrected solutions, are provided throughout the book. Contents 1. Basic Concepts of Electrochemistry used in Electrical Engineering. 2. Water Electrolyzers. 3. Fuel Cells. 4. Electrical Energy Storage by Supercapacitors. 5. Electrochemical Accumulators. 6. Hybrid Electrical System. About the Authors Marie-Cécile Péra is a Full Professor at the University of Franche-Comte in France and Deputy Director of the FEMTO-ST Institute (CNRS).

Available in PDF, EPUB and Kindle. Book excerpt: Over the 20th century, Morocco has become one of the world’s major emigration countries. But since 2000, growing immigration and settlement of migrants from sub-Saharan Africa, the Middle East, and Europe confronts Morocco with an entirely new set of social, cultural, political and legal issues. This book explores how continued emigration and increasing immigration is transforming contemporary Moroccan society, with a particular emphasis on the way the Moroccan state is dealing with shifting migratory realities. The authors of this collective volume embark on a dialogue between theory and empirical research, showcasing how contemporary migration theories help understanding recent trends in Moroccan migration, and, vice-versa, how the specific Moroccan case enriches migration theory. This perspective helps to overcome the still predominant Western-centric research view that artificially divide the world into ‘receiving’ and ‘sending’ countries and largely disregards the dynamics of and experiences with migration in countries in the Global South. This book was previously published as a special issue of The Journal of North African Studies.
