This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de ce mémoire est d'analyser le potentiel des installations photovoltaïques connectées au réseau électrique insulaire. Notre étude porte sur trois types de systèmes: l'intégration de centrales PV dans le réseau électrique, l'utilisation de système PV en toiture pour réduire les chutes de tension en bout de ligne et un système à vocation expérimentale. La première partie offre une analyse détaillée de l'apport du photovoltaïque dans le réseau de distribution d'électricité corse. La simultanéité entre la charge et la puissance fournie par une centrale PV y est étudiée ainsi que le taux de disponibilité effectif plus communément appelé TDE. La deuxième partie du mémoire est consacrée au secteur résidentiel et plus particulièrement au renforcement des bouts de lignes électriques via la solution photovoltaïque. En effet, de nombreux foyers connaissent aujourd'hui encore des problèmes de chutes de tension. Pour assurer à l'usager un confort maximal nous avons donc choisi cette solution car l'île possède un ensoleillement remarquable et que la population est de plus en plus sensibilisée à ce type d'énergie. Enfin, le troisième et dernier chapitre représente la partie expérimentale de cette thèse. Elle concerne la modélisation d'un système photovoltaïque de 850 Wc connecté au réseau électrique et situé sur le site universitaire de Vignola. Le suivi et le monitoring ont été assurés depuis sa mise en service en 2000. Une étude des performances et de l'interaction entre le réseau et l'onduleur ont mis en évidence les problèmes de productions liés aux fluctuations du réseau. Des modi fications nécessaires des paramètres de l' onduleur ont conduits à des performances très satisfaisantes. Ce travail qui constitue une étude très large de l'intégration de systèmes PV dans le réseau insulaire corse à travers des applications variées devra être complété par une étude du secteur administratifs et surtout d'une étude plus poussée de la relation réseau/système PV.

Download or read book Coviability of Social and Ecological Systems Reconnecting Mankind to the Biosphere in an Era of Global Change written by Olivier Barrière and published by Springer. This book was released on 2019-03-12 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume is the work of more than 55 authors from 15 different disciplines and includes complex systems science which studies the viability of components, and also the study of empirical situations. As readers will discover, the coviability of social and ecological systems is based on the contradiction between humanity, which adopts finalized objectives, and the biosphere, which refers to a ecological functions. We see how concrete situations shed light on the coviability’s determinants, and in this book the very nature of the coviability, presented as a concept-paradigm, is defined in a transversal and ontological ways. By adopting a systemic approach, without advocating any economic dogma (such as development) or dichotomizing between humans and nature, while emphasizing what is relevant to humans and what is not, this work neutrally contextualizes man’s place in the biosphere. It offers a new mode of thinking and positioning of the ecological imperative, and will appeal to all those working with social and ecological systems.

Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the management and valuation of energy storage in electric power grids, highlighting the interest of storage systems in grid applications and developing management methodologies based on artificial intelligence tools. The authors highlight the importance of storing electrical energy, in the context of sustainable development, in "smart grids", and discuss multiple services that storing electrical energy can bring. Methodological tools are provided to build an energy management system storage following a generic approach. These tools are based on causal formalisms, artificial intelligence and explicit optimization techniques and are presented throughout the book in connection with concrete case studies.

Download or read book Biodiversity and Health written by Serge Morand and published by Elsevier. This book was released on 2017-11-27 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a gap between the ecology of health and the concepts supported by international initiatives such as EcoHealth, One Health or Planetary Health; a gap which this book aims to fill. Global change is accelerated by problems of growing population, industrialization and geopolitics, and the world’s biodiversity is suffering as a result, which impacts both humans and animals. However, Biodiversity and Health offers the unique opportunity to demonstrate how ecological, environmental, medical and social sciences can contribute to the improvement of human health and wellbeing through the conservation of biodiversity and the services it brings to societies. This book gives an expansive and integrated overview of the scientific disciplines that contribute to the connection between health and biodiversity, from the evolutionary ecology of infectious and non-infectious diseases to ethics, law and politics. Presents the first book to give a broad and integrated overview of the scientific disciplines that contribute to health From evolutionary ecology, to laws and policies, this book explores the links between health and biodiversity Demonstrates how ecological sciences, environmental sciences, medical sciences, and social sciences may contribute to improve human health
Download or read book Ecological Systems written by Rik Leemans and published by Springer Science & Business Media. This book was released on 2012-12-12 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth is home to an estimated 8 million animal species, 600,000 fungi, 300,000 plants, and an undetermined number of microbial species. Of these animal, fungal, and plant species, an estimated 75% have yet to be identified. Moreover, the interactions between these species and their physical environment are known to an even lesser degree. At the same time, the earth’s biota faces the prospect of climate change, which may manifest slowly or extremely rapidly, as well as a human population set to grow by two billion by 2045 from the current seven billion. Given these major ecological changes, we cannot wait for a complete biota data set before assessing, planning, and acting to preserve the ecological balance of the earth. This book provides comprehensive coverage of the scientific and engineering basis of the systems ecology of the earth in 15 detailed, peer-reviewed entries written for a broad audience of undergraduate and graduate students as well as practicing professionals in government, academia, and industry. The methodology presented aims at identifying key interactions and environmental effects, and enabling a systems-level understanding even with our present state of factual knowledge.
Download or read book Grid Connected Renewable Energy Sources written by J. C. Hernandez and published by . This book was released on 2021 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of renewable energy sources (RESs) is a need of global society. This editorial, and its associated Special Issue “Grid-Connected Renewable Energy Sources”, offers a compilation of some of the recent advances in the analysis of current power systems that are composed after the high penetration of distributed generation (DG) with different RESs. The focus is on both new control configurations and on novel methodologies for the optimal placement and sizing of DG. The eleven accepted papers certainly provide a good contribution to control deployments and methodologies for the allocation and sizing of DG.
