Finite Element Methods in CAD

Finite Element Methods in CAD

The finite element method (FEM) has been understood, at least in principle, for more than 50 years. The integral formulation on which it is based has been known for a longer time (thanks to the work of Galerkin, Ritz, Courant and Hilbert,1.4 to mention the most important). However, the method could not be applied in a practical way since it involved the solution of a large number of linear or non-linear algebraic equations. Today it is quite common, with the aid of computers, to solve non-linear algebraic problems of several thousand equations. The necessary numerical methods and programming techniques are now an integral part of the teaching curriculum in most engineering schools. Mechanica...

Power Systems and Restructuring

The development of electric power systems has been made up of incremental innovations from the end of the 19th century and throughout the 20th century. The creation of deregulated electricity markets has brought about an emerging paradigm in which the relationships between producers, power system operators and consumers have changed enormously compared to the monopolistic case. The scope of this book is to provide fundamental concepts of the physics and operation of transmission and distribution lines, which is the content of Part 1, followed by the models and tools for the description and simulation of large electrical grids for steady state and transient operation. These advanced tools all...

Analysis and Design of Multicell DC/DC Converters Using Vectorized Models

Shows how the concepts of vectorization and design masks can be used to help the designer in comparing different designs and making the right choices. The book addresses series and parallel multicell conversion directly, and the concepts can be generalized to describe other topologies.

Finite Element Analysis of Electrical Machines

In Finite Element Analysis of Electrical Machines the author covers two-dimensional analysis, emphasizing the use of finite elements to perform the most common calculations required of machine designers and analysts. The book explains what is inside a finite element program, and how the finite element method can be used to determine the behavior of electrical machines. The material is tutorial and includes several completely worked out examples. The main illustrative examples are synchronous and induction machines. The methods described have been used successfully in the design and analysis of most types of rotating and linear machines. Audience: A valuable reference source for academic researchers, practitioners and designers of electrical machinery.

Electrical Energy Storage in Transportation Systems

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 cities" and "smart transportation", 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.

Distribution System Planning

Distribution systems drive energy and societal transition. System planning enables investments to be made in the right place, at the right time and with the right technology. Distribution System Planning is centered on the evolution of planning methods that will best support this transition, and describes the historical context and concepts that enable planning, its challenges and key influencing factors to be grasped. It also analyzes the impact of the development of renewable and decentralized energy resources, government recommendations and distributor initiatives to promote their integration. Through the use of case studies, this book provides examples of how planning methodologies have evolved, as well as an overview of new and emerging solutions.

Advanced Smartgrids for Distribution System Operators, Volume 1

The dynamic of the Energy Transition is engaged in many region of the World. This is a real challenge for electric systems and a paradigm shift for existing distribution networks. With the help of "advanced" smart technologies, the Distribution System Operators will have a central role to integrate massively renewable generation, electric vehicle and demand response programs. Many projects are on-going to develop and assess advanced smart grids solutions, with already some lessons learnt. In the end, the Smart Grid is a mean for Distribution System Operators to ensure the quality and the security of power supply. Several books have been written to provide a definition of Smart grids, explore the different technical evolution needed and explain / analyse what would be the benefits. All those books are conducted on theoretical basis by academics and strategy consultants. This new book will propose a complementary and singular approach based on a practical experience from DSO's.

  • Publisher: Lavoisier

L'avènement de la libéralisation des marchés de l'énergie a été un facteur clé de succès du développement des énergies renouvelables et de la maîtrise de la demande en énergie. L'insertion massive des productions décentralisées intermittentes sur les réseaux de distribution engendre une complexité de fonctionnement qui est préjudiciable à la sécurité. L'introduction des technologies de l'information et de la communication permet de pallier cette difficulté et ouvre des perspectives nouvelles dans la maîtrise de la demande énergétique en intégrant le consommateur dans le pilotage du réseau. C'est l'objet de l'ouvrage consacré aux réseaux intelligents connus sous le nom de SmartGrids. Le concept de Smartgrids est abordé sous diverses facettes par l'aspect commercial, économiques, réglementaire par des auteurs spécialistes de ces questions. La partie technique est abordée à la fois par l'aspect énergétique et celui des télécommunications et du comptage.

Electromagnetic Fields in Electrical Engineering

This book is the collection of the contributions offered at the International Symposium on Electromagnetic Fields in Electrical Engineering, ISEF '87, held in Pavia, Italy, in September 1987. The Symposium was attended by specialists engaged in both theoretical and applied research in low-frequency electromagnetism. The charming atmosphere of Pavia and its ancient university provided a very effective environment to discuss the latest results in the field and, at the same time, to enjoy the company or colleagues and friends coming from over 15 countries. The contributions have been grouped into 7 chapters devoted to fundamental problems, computer programs, transformers, rotating electrical ma...
