Distributed Energy and Smart Grids: Sustainable Energy for the Future explores the transition from traditional centralised power systems to intelligent, decentralised, and sustainable energy infrastructures. Focusing on the integration of Distributed Energy Resources (DERs) such as solar, wind, and emerging renewables with advanced smart grid technologies, this book highlights how digital communication, automation, and real-time analytics are reshaping modern energy systems. The book covers critical topics including renewable energy integration, grid stability, energy storage and battery management, IoT-based monitoring, communication technologies, cybersecurity, SCADA systems, demand-response mechanisms, and the roles of AI, machine learning, and electric vehicles in next-generation grids. Case studies, emerging innovations, and future trends provide practical insights and real-world applications for researchers and professionals alike. Key Features: Comprehensive coverage of distributed energy systems and smart grid integration Clear explanations supported by illustrations, case studies, and practical solutions Insights into renewable adoption, grid modernisation, and emerging technologies
