Dwindling fossil fuel resources, rising global energy demand and the need to reduce the environmental impact of greenhouse gas emissions are major challenges that require effective solutions. Against this backdrop, the development of renewable energies and demand management are emerging as promising alternatives. To meet these challenges, intelligent strategies are needed to manage energy production, regulate its integration into the power grid and maintain a constant balance between supply and demand.Talking about smart grids also implies discussing optimal energy management, which is the key to making these grids more efficient and profitable. At the end of the book, therefore, we have drawn up a bibliographical review of the various energy optimization techniques and algorithms.This book is just a glimpse into a vast field of research into the power networks of the future.
