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. Topics covered include an introduction to smart grid architecture; smart grid communications and standards; measurement and sensing devices for smart grids; smart transmission and wide area monitoring system; bad data detection in smart grids; optimal energy management in smart grids; communication and control for the smart grid; smart consumer systems; importance of energy storage systems in smart grids; control and optimization for integration of plug-in vehicles in smart grids; multi-agent based control of smart grids; compressive sensing for smart grid security and reliability; optimum placement of FACTS devices in smart grids; security analysis of smart grid; and smart grid security policies and regulations. With contributions from prominent researchers in the fields of computer, communication, and power engineering this book is essential reading for researchers in power grids, as well as for advanced students and practitioners.
