Book excerpt: Les limites des ressources d'énergies fossiles et la perspective imminente du changement climatique ont mené les pays de l'Union Européenne à engager une restructuration du secteur électrique vers un approvisionnement en énergie fiable, économique et durable. Dans cette optique de transition énergétique, les systèmes de stockage d'énergie peuvent faciliter l'intégration des énergies renouvelables dans les réseaux électriques. Ils permettent de stocker l'énergie produite par les sources renouvelables pour décaler sa fourniture aux réseaux électriques et compenser les fluctuations aléatoires de la puissance. Par ce lissage de la production des sources intermittentes, les systèmes de stockage transforment ces dernières en centrales mieux contrôlables et plus prévisibles ce qui leur permet de participer aux marchés d'électricité et aux services systèmes.Afin de garantir le respect des plans de production et des engagements pris envers le gestionnaire du réseau, les centrales de production renouvelables équipées d'un système de stockage ont recours à un système de gestion d'énergie. Alors que le contrôle rapproché assure le respect de la consigne instantanée de production, la gestion d'énergie utilise des méthodes d'optimisation sous contraintes issues de la recherche opérationnelle pour planifier le fonctionnement des systèmes de stockage. Le plus souvent, un arbitrage est nécessaire entre les exigences du fonctionnement et la complexité du modèle utilisé. Les modèles de batterie, qui présentent un comportement non-linéaire, doivent être simplifiés en vue de les intégrer dans les algorithmes d'optimisation les plus courants. De plus, les modèles précis et particulièrement ceux qui sont basés sur une modélisation physico-chimique de la batterie exigent des tests de caractérisation chronophages réalisés dans des conditions contrôlées. Finalement, le comportement électrique de la batterie évolue avec son âge ce qui impose un recalage périodique du modèle en fonction du temps.Cette thèse présente une méthodologie d'identification de modèles de batterie en cours de fonctionnement et d'utilisation de ces modèles adaptatifs dans la gestion optimale d'une centrale de production électrique avec stockage. Après un rappel des modèles de batteries, des méthodes d'identification en temps réel issues de la théorie du contrôle sont développées dans le cas d'un modèle des circuits électriques équivalents. L'extraction d'un modèle simplifié pour la gestion d'énergie est décrite et juxtaposée à une analyse de régression directe des données de fonctionnement. Les méthodes d'identification sont testées pour un système de stockage réel de taille industrielle, associé à une centrale photovoltaïque installée sur l'île de La Réunion. L'identification du modèle dans le cadre d'une étude de vieillissement préalablement effectuée au sein du CEA, met en évidence le suivi de l'état de santé de la batterie.En vue de l'intégration des modèles adaptatifs dans la gestion, la formulation des problèmes d'optimisation rencontrés dans la planification d'une centrale photovoltaïque associée à un système de stockage est développée. Des implémentations en programmation linéaire-mixte et en programmation dynamique sont réalisées dans des cas d'études basés sur la participation aux marchés d'électricité ou dans le cadre d'une tarification réglementée, ainsi que la participation aux services système. Afin d'évaluer les performances de ces solutions, une architecture de contrôle pour la centrale est détaillée, et le fonctionnement de la centrale est simulé. Plusieurs configurations du système de gestion sont testées, y compris l'utilisation de modèles fixes ou variables ainsi que la prise en compte ou non du vieillissement de la batterie. Une analyse statistique des résultats obtenus pour différents cas de production photovoltaïque et d'erreurs de prévision montre que l'utilisation des modèles variables présente des avantages.

Book Synopsis An Introduction to Computational Learning Theory by : Michael J. Kearns
Download or read book An Introduction to Computational Learning Theory written by Michael J. Kearns and published by MIT Press. This book was released on 1994-08-15 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Emphasizing issues of computational efficiency, Michael Kearns and Umesh Vazirani introduce a number of central topics in computational learning theory for researchers and students in artificial intelligence, neural networks, theoretical computer science, and statistics. Computational learning theory is a new and rapidly expanding area of research that examines formal models of induction with the goals of discovering the common methods underlying efficient learning algorithms and identifying the computational impediments to learning. Each topic in the book has been chosen to elucidate a general principle, which is explored in a precise formal setting. Intuition has been emphasized in the presentation to make the material accessible to the nontheoretician while still providing precise arguments for the specialist. This balance is the result of new proofs of established theorems, and new presentations of the standard proofs. The topics covered include the motivation, definitions, and fundamental results, both positive and negative, for the widely studied L. G. Valiant model of Probably Approximately Correct Learning; Occam's Razor, which formalizes a relationship between learning and data compression; the Vapnik-Chervonenkis dimension; the equivalence of weak and strong learning; efficient learning in the presence of noise by the method of statistical queries; relationships between learning and cryptography, and the resulting computational limitations on efficient learning; reducibility between learning problems; and algorithms for learning finite automata from active experimentation.

Book Synopsis Reinforcement Learning, second edition by : Richard S. Sutton
Download or read book Reinforcement Learning, second edition written by Richard S. Sutton and published by MIT Press. This book was released on 2018-11-13 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significantly expanded and updated new edition of a widely used text on reinforcement learning, one of the most active research areas in artificial intelligence. Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives while interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the field's key ideas and algorithms. This second edition has been significantly expanded and updated, presenting new topics and updating coverage of other topics. Like the first edition, this second edition focuses on core online learning algorithms, with the more mathematical material set off in shaded boxes. Part I covers as much of reinforcement learning as possible without going beyond the tabular case for which exact solutions can be found. Many algorithms presented in this part are new to the second edition, including UCB, Expected Sarsa, and Double Learning. Part II extends these ideas to function approximation, with new sections on such topics as artificial neural networks and the Fourier basis, and offers expanded treatment of off-policy learning and policy-gradient methods. Part III has new chapters on reinforcement learning's relationships to psychology and neuroscience, as well as an updated case-studies chapter including AlphaGo and AlphaGo Zero, Atari game playing, and IBM Watson's wagering strategy. The final chapter discusses the future societal impacts of reinforcement learning.
Book Synopsis Digital Transformation in Financial Services by : Claudio Scardovi
Download or read book Digital Transformation in Financial Services written by Claudio Scardovi and published by Springer. This book was released on 2017-09-04 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the set of forces driving the global financial system toward a period of radical transformation and explores the transformational challenges that lie ahead for global and regional or local banks and other financial intermediaries. It is explained how these challenges derive from the newly emerging post-crisis structure of the market and from shadow and digital players across all banking operations. Detailed attention is focused on the impacts of digitalization on the main functions of the financial system, and particularly the banking sector. The author elaborates how an alternative model of banking will enable banks to predict, understand, navigate, and change the external ecosystem in which they compete. The five critical components of this model are data and information mastering; effective use of applied analytics; interconnectivity and “junction playing”; development of new business solutions; and trust and credibility assurance. The analysis is supported by a number of informative case studies. The book will be of interest especially to top and middle managers and employees of banks and financial institutions but also to FinTech players and their advisers and others.
Book Synopsis Simply This... Amen. by : Donna McLin
Download or read book Simply This... Amen. written by Donna McLin and published by . This book was released on 2019-12 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This prayer book was written over a two-year span. The prayers started one night when my daughter and I could not sync our time to pray together on one particular night in March 2017. While preparing for bed, the Lord said to me, "Just write a prayer and put it on Facebook". I did and the rest is history. You are now holding what it is that the Lord has done with these prayers. Each night with the exception of being away from home with no phone service, or during times of fasting, I wrote a prayer each night and posted them on Facebook. I have been told by many people along the way that they do not know how to pray. It is my prayer that this book will be a foundation for those who feel that they do not know how to pray or who simply need a prayer devotional.

Book Synopsis Introduction to Nonsmooth Optimization by : Adil Bagirov
Download or read book Introduction to Nonsmooth Optimization written by Adil Bagirov and published by Springer. This book was released on 2014-08-12 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first easy-to-read text on nonsmooth optimization (NSO, not necessarily differentiable optimization). Solving these kinds of problems plays a critical role in many industrial applications and real-world modeling systems, for example in the context of image denoising, optimal control, neural network training, data mining, economics and computational chemistry and physics. The book covers both the theory and the numerical methods used in NSO and provide an overview of different problems arising in the field. It is organized into three parts: 1. convex and nonconvex analysis and the theory of NSO; 2. test problems and practical applications; 3. a guide to NSO software. The book is ideal for anyone teaching or attending NSO courses. As an accessible introduction to the field, it is also well suited as an independent learning guide for practitioners already familiar with the basics of optimization.

Book Synopsis Nonsmooth Optimization by : Claude Lemarechal
Download or read book Nonsmooth Optimization written by Claude Lemarechal and published by Elsevier. This book was released on 2014-05-19 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonsmooth Optimization contains the proceedings of a workshop on non-smooth optimization (NSO) held from March 28 to April 8,1977 in Austria under the auspices of the International Institute for Applied Systems Analysis. The papers explore the techniques and theory of NSO and cover topics ranging from systems of inequalities to smooth approximation of non-smooth functions, as well as quadratic programming and line searches. Comprised of nine chapters, this volume begins with a survey of Soviet research on subgradient optimization carried out since 1962, followed by a discussion on rates of convergence in subgradient optimization. The reader is then introduced to the method of subgradient optimization in an abstract setting and the minimal hypotheses required to ensure convergence; NSO and nonlinear programming; and bundle methods in NSO. A feasible descent algorithm for linearly constrained least squares problems is described. The book also considers sufficient minimization of piecewise-linear univariate functions before concluding with a description of the method of parametric decomposition in mathematical programming. This monograph will be of interest to mathematicians and mathematics students.
