This book focuses on novel techniques in the four domains of new energy development, large-scale energy storage, multi-energy dispatch and new energy applications. The content will make valuable contributions to professionals of industry and academia, since most of the authors are professors or senior engineers with rich experiences of practices, and typical challenges faced by the industry will be discussed and solutions will be introduced except for unfolding spectacular insights of research. Regulators of energy authorities will also find it helpful, since the future of energy will be expounded and new ideas for realizing the formation of new energy-dominated and more efficient and safer power system will be encountered.
