Can renewable energy provide reliable power? Will it need extensive backup? The energy available from wind, waves, tides and the sun varies in ways that may not match variations in energy demand. Assimilating these fluctuations can affect the operation and economics of electricity networks, markets and the output of other forms of generation. Is this a significant problem, or can these new sources be integrated into the grid system without the need for extensive backup or energy storage capacity? This book examines the significance of the issue of variability of renewable electricity supplies, and presents technical and operational solutions to the problem of reconciling the differing patterns of supply and demand. Its chapters are authored by leading experts in the field, who aim to explain and quantify the impacts of variability in renewable energy, and in doing so, dispel many of the myths and misunderstandings surrounding the topic.

The rapid growth of wind generation has many implications for power system planning, operation and control. Network development, voltage rise, protection, monitoring and control are connection problems common to all wind power generation. Wind Power Integration: Connection and System Operational Aspects, 2nd edition has been fully revised and updated to take account of the significant growth in wind power deployment in the past few years to provide a wide-ranging discussion on all major aspects of wind power integration into electricity supply systems. Topics covered include: the development of wind power technology and its world-wide deployment a primer in electric power engineering for non-electrical engineers - which system delivers significant wind energy to consumers at least cost? wind power technology and the interaction of various wind turbine generator types with the utility network utility networks, and how they may be developed to accept significant wind power how operational practice can be modified to take account of a variable power source with limited scope for control wind power forecasting the challenges faced by wind energy in modern electricity markets This second edition has been fully revised and updated to take account of the significant growth in wind power deployment in the past few years. New discussions have been added to describe developments in wind turbine generator technology and control, the network integration of wind power, innovative ways to integrate wind power when its generation potential exceeds 50% of demand, case studies on how forecasting errors have affected system operation, and an update on how the wind energy sector has fared in the marketplace. Wind Power Integration: Connection and System Operational Aspects, 2nd edition will appeal to engineers from various disciplines looking for an overview of a technology that is providing a major impetus for sustainable electricity supply in the twenty-first century.

The rapid growth of wind generation has many implications for power system planning, operation and control. This would have been a considerable challenge for the old nationalised power companies; it has become an even greater challenge in today's liberalised electricity markets. Network development, voltage rise, protection, monitoring and control are connection problems common to all wind power generation. These issues are addressed through an understanding of the basic electrical engineering concepts and wind power technology. When wind power approaches 10 percent of all generation, it impinges on system operation. The underlying principles of system balancing are presented, before considering the impact of many variable generation sources whose outputs are difficult to predict. Wind power forecasting is crucial to successful wind power integration, and basic theory and current practice are considered. Storage can also help but it needs to be low cost and, ideally, based on intelligent use of existing load. Finally, electricity markets are explained and the commercial challenges facing wind power are assessed. The book provides a wide-ranging discussion on all major aspects of wind power integration into electricity supply systems. It requires no specialist knowledge and will appeal to engineers from various disciplines looking for an overview of a technology that is providing a major impetus for sustainable electricity supply in the twenty-first century.
