✦ Synopsis

Over several decades, models, techniques and application tools were developed that recognised the central nature of generation, and there are many excellent texts that relate to and describe the assessment of such systems. However, some very specific features of distributed generation, namely that large numbers of relatively small generators are distributed around the system, often connected into relatively weak distribution networks mean that existing techniques and practices have had to be reviewed and updated to take these features into account. The questions raised by large numbers of distributed generators and their control within a de-regulated commercial environment (Virtual Power Plants), Active Network Management and Microgrids are also addressed. This book is the outcome of the authors' experience teaching courses on Distributed Generation to undergraduate and MSc students in the UK, USA and Sri Lanka. Many Universities are now offering courses on Renewable Energy and how sustainable, low-carbon generation can be integrated effectively into the distribution system. The book has four tutorial chapters (with examples and questions) to provide fundamental material for those without a strong electrical engineering background. Non-specialists may then benefit from the main body of the text once they have studied the tutorial material. Also available:Biofuels - ISBN 9780863419591Off Shore Wind - ISBN 9780863419607This new series of books from the IET brings together the engineering aspects of renewable energy technology, power generation and systems integration. Covering all aspects of renewable and sustainable power and highlighting the key principles behind each technology, its state of development and its relevance in the power industry. With energy and sustainability being areas of primary concern, these books are practical in approach and appeal to specialists and non-specialists alike, providing a thorough understanding to the economical and environmental issues as well as key engineering features.The Institution of Engineering and Technology is one of the world's leading professional societies for the engineering and technology community. The IET publishes more than 100 new titles every year; a rich mix of books, journals and magazines with a back catalogue of more than 350 books in 18 different subject areas including: -Power & Energy -Renewable Energy -Radar, Sonar & Navigation -Electromagnetics -Electrical Measurement -History of Technology -Technology Management
