Smart Prosumers within Smart Grids: Fundamentals, Methodologies, and Potential for Advancing the Energy Transition offers a holistic primer on the technologies and opportunities of prosumer integration into smart grids. This book begins with a clear introduction to the essential concepts of both smart grids and prosumers, as well as their critical role in renewable energy integration. It then moves through a 360-degree analysis of opportunities for leveraging smart prosumer technology in the smart grid, from the micro (smart homes) to macro (smart distribution networks and interconnected smart power-gas grids). Methodologies to maximise integration of renewable sources including critical hydrogen technologies are considered, as well as the potential for smart prosumers to manager reliability challenges of renewable energy and constant change from the energy transition. Implications are considered across sectors including regulatory, legal, economic, business, and transport infrastructure, and prosumer interactions with other actors such as DSOs, TSOs, retailers, and BPRs are analysed. Combining cutting-edge technical research with industry experience, 'Smart Prosumers within Smart Grids' provides an in-depth analysis of the opportunities and challenges for this technology in the quest for renewable energy integration.
