The Smart Grid is a modern electricity grid allowing for distributed, renewable intermittent generation, partly owned by consumers. This requires advanced control and communication technologies in order to provide high quality power supply and secure generation, transmission and distribution. This book outlines these emerging technologies.

Smart grids are electrical grids using ICT and two-way communications to enable varying two-way flows of electricity and information for the integration of distributed renewable generation and power storage. Research and development in this field centres on three main areas; the infrastructure system, the management system, and the protection. The integration of advanced communication, sensing, control, and optimization techniques into traditional power systems is a key challenge in transforming conventional grids into smart grids, and so empowering consumers with real-time information and control over their power usage and production.

A microgrid is a small network of electricity users with a local source of supply that is usually attached to a larger grid but can function independently. The interconnection of small scale generating units, such as PV and wind turbines, and energy storage systems, such as batteries, to a low voltage distribution grid involves three major challenges: variability, scalability, and stability. It must keep delivering reliable and stable power also when changing, or repairing, any component, or under varying wind and solar conditions. It also must be able to accept additional units, i.e. be scalable. This reference discusses these three challenges facing engineers and researchers in the field of power systems, covering topics such as demand side energy management, transactive energy, optimizing and sizing of microgrid components. Case studies and results provide illustrative examples in each chapter.
