Considerable insight and information are provided for anyone wanting to learn more about the challenges and opportunities for integrating renewables into power systems. --IEEE Like many other industries, the energy sector is undergoing a transformation. As a number of countries strive to reduce the environmental footprint of their energy production, new technologies are opening up unforeseen possibilities and challenging the status quo. There is no doubt that renewable energy, including hydropower, is part of the solution. This work brings together a wide range of information and visions to better understand the importance of developing and integrating various sources of clean energy in order to ensure the long-term viability of our industry and to help society move towards sustainability. In short, this forward-looking work will educate and equip readers for the future. --Eric Martel, President and Chief Executive Officer, Hydro-Quebec We are living through a second Renaissance. And as this, the 2nd edition of Renewable Energy Integration, makes clear, nowhere are the possibilities and stakes of this Renaissance moment clearer than in our energy infrastructure. Now is a moment, like 500 years ago, when humanity sets out on brave new voyages of discovery-voyages whose outcome is uncertain. This book takes what we've found so far from these voyages and expertly compiles the definitive map of the renewable energy landscape as we now know it: from Africa, to India, to Denmark and California; from pumped hydro to compressed air storage; from market management systems to smart grid operations; from residential batteries to global power distribution. It's a must-read for every captain, every pilot of our energy renaissance. --Dr. Chris Kutarna, Author, Age of Discovery: Navigating the Risks and Rewards of Our New Renaissance Jones has once again assembled an impressive set of authors to address one of the most pressing issues of our time - how to operate electricity systems with high levels of renewables. While the authors are highly technically qualified, their chapters are wonderfully clear and accessible to non-specialists. I expect this volume will be a valuable resource for practitioners, students, and policymakers around the world. --Dr. Catherine Wolfram, Cora Jane Flood Professor of Business Administration at the Haas School of Business, University of California, Berkeley
