This book was released on 2012-11-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le contexte économique impose des systèmes toujours plus performants, minimisant coûts d’investissement et de possession. Si les méthodes d’analyse, de synthèse et de gestion présentées dans le premier volume Conception systémique pour la conversion d’énergie électrique 1 participent à l’optimisation des systèmes énergétiques, les techniques traitées dans cet ouvrage proposent d’aller encore plus loin dans la performance. La complexité de systèmes multidisciplinaires à fort degré de couplage augmentant, le processus de conception par optimisation consistant à coupler un modèle à un algorithme d’optimisation au sein d’un environnement logiciel devient dès lors indispensable. Ce volume rassemble les points-clés permettant de représenter efficacement et de façon compacte l’environnement système et les profils de mission, mais également les méthodes, modèles et outils dédiés à l’optimisation. Les approches multiniveaux de conception et l’optimisation technico-économique des réseaux électriques sont particulièrement détaillées.

This book was released on 2014-01-10 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les nanotechnologies apportent un fort potentiel d’innovation et de rupture dans de nombreux domaines. Leurs applications pour l’énergie en est un champ important, car la synthèse et la structuration des nanomatériaux y ouvrent des voies de progrès notables. Si divers ouvrages décrivent les innovations promises par les nanotechnologies sur des thématiques scientifiques générales ou spécialisées, très peu abordent le chemin qui va des nouvelles propriétés aux applications pour l’énergie électrique et ses usages. Cet ouvrage présente, sur des bases scientifiques solides, les apports des nanotechnologies et plus particulièrement des nanomatériaux aux enjeux de la production d’électricité et de ses usages. Après un panorama des effets physiques qui peuvent être exploités à ces échelles pour améliorer les propriétés des matériaux ou leur fonctionnalité, leur application à la production d’électricité, à son stockage, à ses usages ainsi qu’au traitement de questions environnementales est abordée. Elle conduit à explorer les domaines de l’électrochimie, du photovoltaïque, de la thermoélectricité, des propriétés mécaniques et thermiques des matériaux ou encore des membranes et des surfaces ultrahydrophobes. Chaque chapitre constitue une monographie exhaustive enrichie d’une abondante iconographie et d’une bibliographie très complète. Les meilleurs experts de chaque domaine ont été réunis, faisant de cet ouvrage une référence incontournable. Au confluent de plusieurs disciplines et en prise directe sur un vaste champ d’applications, ce livre s’adresse à un large public : ingénieurs et chercheurs, étudiants des écoles d’ingénieurs ou des universités aux niveaux licence et master.

This book was released on 2012-11-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le contexte actuel mène les concepteurs vers des systèmes toujours plus complexes et performants, intégrant un grand nombre d’éléments souvent fortement couplés et appartenant à divers champs de la physique énergétique. Après une présentation de l’approche systémique de conception, ce premier volume rassemble les points-clés permettant de modéliser et de caractériser efficacement des systèmes multiphysiques (formalismes graphiques, Bond Graphs, GIC/REM), d’analyser la qualité et la stabilité des réseaux et de contribuer à la robustesse en conception intégrée. La gestion de l’énergie des systèmes énergétiques hybrides incluant du stockage est également largement détaillée et différentes méthodes statistiques permettant de dimensionner les réseaux ou de caractériser leur sûreté de fonctionnement sont proposées (par exemple, la méthode de Monte-Carlo). Les techniques d’analyse, de synthèse et de gestion présentées dans cet ouvrage participent à l’optimisation des systèmes énergétiques. Elles sont complétées par des approches spécifiquement orientées vers la conception par optimisation, objets du second volume.

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).
