As wind becomes a significant contributor to meeting electric power needs around the world, there is an increasing need for regulators, engineers, planners, and utility managers to understand the interaction of wind generation with modern power systems. The book will include contributions from national and international experts on wind generation to lay out the present state of knowledge on wind energy. Beginning with a short history of wind technology, the book will present analytical techniques for addressing wind's interaction with other resources on the grid as well as the results of in-depth wind integration studies that have been undertaken. It will also review policy issues with respect to promoting and responsible siting of renewable resources. The central purpose of the book will be to provide the background needed by analysts, regulators, planners, and policy consultants to understand the opportunities, costs, and challenges relating to the burgeoning development of wind power.
