Book excerpt: La gestion de la distribution de l'énergie électrique produite à partir de sources renouvelables comme l'énergie solaire et l'énergie éolienne est un verrou technologique pour améliorer les performances et la stabilité de l'ensemble des processus de transfert d'énergie. Ainsi, les recherches sur les lignes électriques utilisées comme supports de communication sont très prometteuses pour la gestion d'installation de petites et moyennes puissances comprenant de nombreux générateurs, pas forcément conçus initialement dans une démarche de fiabilité. En outre, cette nouvelle possibilité de gestion permet d'améliorer les performances et la stabilité dans le processus de transfert global d'énergie. Cette étude est particulièrement orientée vers une architecture distribuée pour la gestion photovoltaïque parallèle et/ou multi-générateurs incluant d'autres technologies telles que l'éolien par exemple connectés sur un réseau à courant continu servant également de support de communication tel que le système CPL. Le CPL, en utilisant la technique de modulation, permet le transfert de l'information telles que la température, la puissance instantanée, l'auto-test etc... nécessaires pour optimiser la production d'énergie. Le but de ce travail consiste en l'étude d'une solution CPL conçue pour travailler sur bus HVDC reliant des systèmes de production d'énergie renouvelable. Les circuits développés pour le CPL seront donc considérés comme des interfaces entre le convertisseur intelligent DC-DC et le bus HVDC. Ils seront basés sur une partie matérielle constituée d'un émetteur-récepteur intégrant une interface de modulation-démodulation sur le bus HVDC et un processeur de signal assurant le traitement des diverses informations échangées entre les capteurs d'entrées et le monitoring.

This book was released on 2009 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les recherches actives sur les matériaux photovoltaïques et sur les systèmes de gestion de cette énergie sont à la base de ces progrès constants. Le LAAS travaille depuis plusieurs années dans cette optique d'amélioration et d'optimisation de l'énergie électrique produite par les systèmes solaires photovoltaïques. L'insertion d'un étage d'adaptation entre un générateur photovoltaïque (PV) et une charge optimise le transfert d'énergie. Ainsi, cet étage, commandé par une MPPT (Maximum Power Point Tracking), permet de rechercher en permanence le point maximum de puissance délivré par le module PV. Afin d'accroître encore les performances énergétiques des systèmes solaires, cette thèse s'est délibérément orientée vers une architecture fortement distribuée. Cette approche, consistant à répartir la gestion du générateur PV, permet de se rapprocher au plus près de la production photovoltaïque et ainsi en optimiser la puissance électrique globalement produite. Pour cela, nous avons développé des prototypes de micro-convertisseurs dédiés aux applications faibles puissances photovoltaïques. Les mesures journalières effectuées nous ont permis d'étudier avec précision l'intérêt de l'architecture distribuée et d'obtenir des résultats de validation montrant les perspectives à venir. Plusieurs solutions d'architectures se dégagent avec différents bilans des gains énergétiques qu'elles apportent.

Available in PDF, EPUB and Kindle. Book excerpt: Pour faire face aux mutations du paysage énergétique, les réseaux de distribution d'électricité sont soumis à des exigences de fonctionnement avec des indices de fiabilité à garantir. Dans les années à venir, de grands investissements sont prévus pour la construction des réseaux électriques flexibles, cohérents et efficaces, basés sur de nouvelles architectures et des solutions techniques innovantes, adaptatifs à l'essor des énergies renouvelables. En prenant en compte ces besoins industriels sur le développement des réseaux de distribution du futur, nous proposons, dans cette thèse, une approche reposant sur la théorie des graphes et l'optimisation combinatoire pour la conception de nouvelles architectures pour les réseaux de distribution. Notre démarche consiste à étudier le problème général de recherche d'une architecture optimale qui respecte l'ensemble de contraintes topologiques (redondance) et électrotechniques (courant maximal, plan de tension) selon des critères d'optimisation bien précis : minimisation du coût d'exploitation (OPEX) et minimisation de l'investissement (CAPEX). Ainsi donc, les deux familles des problèmes combinatoires (et leurs relaxations) ont été explorées pour proposer des résolutions efficaces (exactes ou approchées) du problème de planification des réseaux de distribution en utilisant une formulation adaptée. Nous nous sommes intéressés particulièrement aux graphes 2-connexes et au problème de flot arborescent avec pertes quadratiques minimales. Les résultats comparatifs de tests sur les instances de réseaux (fictifs et réels) pour les méthodes proposées ont été présentés.

Available in PDF, EPUB and Kindle. Book excerpt: In The System of Professions Andrew Abbott explores central questions about the role of professions in modern life: Why should there be occupational groups controlling expert knowledge? Where and why did groups such as law and medicine achieve their power? Will professionalism spread throughout the occupational world? While most inquiries in this field study one profession at a time, Abbott here considers the system of professions as a whole. Through comparative and historical study of the professions in nineteenth- and twentieth-century England, France, and America, Abbott builds a general theory of how and why professionals evolve.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects
Download or read book eIoT written by Steffi O. Muhanji and published by Springer. This book was released on 2019-02-20 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book explores the collision between the sustainable energy transition and the Internet of Things (IoT). In that regard, this book’s arrival is timely. Not only is the Internet of Things for energy applications, herein called the energy Internet of Things (eIoT), rapidly developing but also the transition towards sustainable energy to abate global climate is very much at the forefront of public discourse. It is within the context of these two dynamic thrusts, digitization and global climate change, that the energy industry sees itself undergoing significant change in how it is operated and managed. This book recognizes that they impose five fundamental energy management change drivers: 1.) the growing demand for electricity, 2.) the emergence of renewable energy resources, 3.) the emergence of electrified transportation, 4.) the deregulation of electric power markets, 5.) and innovations in smart grid technology. Together, they challenge many of the assumptions upon which the electric grid was first built. The goal of this book is to provide a single integrated picture of how eIoT can come to transform our energy infrastructure. This book links the energy management change drivers mentioned above to the need for a technical energy management solution. It, then, describes how eIoT meets many of the criteria required for such a technical solution. In that regard, the book stresses the ability of eIoT to add sensing, decision-making, and actuation capabilities to millions or perhaps even billions of interacting “smart" devices. With such a large scale transformation composed of so many independent actions, the book also organizes the discussion into a single multi-layer energy management control loop structure. Consequently, much attention is given to not just network-enabled physical devices but also communication networks, distributed control & decision making, and finally technical architectures and standards. Having gone into the detail of these many simultaneously developing technologies, the book returns to how these technologies when integrated form new applications for transactive energy. In that regard, it highlights several eIoT-enabled energy management use cases that fundamentally change the relationship between end users, utilities, and grid operators. Consequently, the book discusses some of the emerging applications for utilities, industry, commerce, and residences. The book concludes that these eIoT applications will transform today’s grid into one that is much more responsive, dynamic, adaptive and flexible. It also concludes that this transformation will bring about new challenges and opportunities for the cyber-physical-economic performance of the grid and the business models of its increasingly growing number of participants and stakeholders.
Download or read book Smart Cities written by Antoine Picon and published by John Wiley & Sons. This book was released on 2015-11-16 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: As cities compete globally, the Smart City has been touted as the important new strategic driver for regeneration and growth. Smart Cities are employing information and communication technologies in the quest for sustainable economic development and the fostering of new forms of collective life. This has made the Smart City an essential focus for engineers, architects, urban designers, urban planners, and politicians, as well as businesses such as CISCO, IBM and Siemens. Despite its broad appeal, few comprehensive books have been devoted to the subject so far, and even fewer have tried to relate it to cultural issues and to assume a truly critical stance by trying to decipher its consequences on urban space and experience. This cultural and critical lens is all the more important as the Smart City is as much an ideal permeated by Utopian beliefs as a concrete process of urban transformation. This ideal possesses a strong self-fulfilling character: our cities will become 'Smart' because we want them to. This book opens with an examination of the technological reality on which Smart Cities are built, from the chips and sensors that enable us to monitor what happens within the infrastructure to the smartphones that connect individuals. Through these technologies, the urban space appears as activated, almost sentient. This activation generates two contrasting visions: on the one hand, a neo-cybernetic ambition to steer the city in the most efficient way; and on the other, a more bottom-up, participative approach in which empowered individuals invent new modes of cooperation. A thorough analysis of these two trends reveals them to be complementary. The Smart City of the near future will result from their mutual adjustment. In this process, urban space plays a decisive role. Smart Cities are contemporary with a 'spatial turn' of the digital. Based on key technological developments like geo-localisation and augmented reality, the rising importance of space explains the strategic role of mapping in the evolution of the urban experience. Throughout this exploration of some of the key dimensions of the Smart City, this book constantly moves from the technological to the spatial as well as from a critical assessment of existing experiments to speculations on the rise of a new form of collective intelligence. In the future, cities will become smarter in a much more literal way than what is often currently assumed.
