Fundamentals of Smart Grid Systems offers an expansive introduction to the operationalization, integration, and management of smart grids-the distributed, renewable, responsive, and highly efficient power grid on the verge of radically transforming our energy system. The book reviews the design of smart grid systems, their associated technologies, and operations, helping users develop a modern foundational understanding of smart grid systems and many of their advanced implementations, where sophisticated technologies are employed. The work serves as a guidebook and primer for early career researchers, with a rich integration of current science, modern applications, and future implementations.Presents critical enabling technologies of smart grid systems alongside relevant aspects of their design, modeling, control, and operations, accompanied by numerical examplesDiscusses how to approach the integration and management of renewable energy sources in smart grid environmentsFeatures didactic pedagogical elements, including end-of-chapter problems, supplemental slideshows, and figurative elements to clarify and explain complex conceptsFocuses on modern applications and current implementations in industry, such as power electronics for smart grids, AI and machine learning-driven modeling, advanced control strategies, and electric vehicles
