Future Grid Architectures

The next-generation electric power systems (smart grid) are studied intensively as a promising solution to the energy crisis. One important feature of the smart grid is the integration of high-speed, reliable, and secure data communication networks to manage the complex power systems effectively and intelligently. We provide in this chapter a comprehensive survey of the communication architectures in the power systems, including the communication network compositions, technologies, functions, requirements, and research challenges. As these communication networks are responsible for delivering power system-related messages, we discuss specifically the network implementation considerations and challenges in the power system settings.
