<p>Electric power systems worldwide face radical transformation with the need to decarbonise electricity supply, replace ageing assets and harness new information and communication technologies (ICT). The Smart Grid uses advanced ICT to control next generation power systems reliably and efficiently. This authoritative guide demonstrates the importance of the Smart Grid and shows how ICT will extend beyond transmission voltages to distribution networks and customer-level operation through Smart Meters and Smart Homes.</p> <p><i>Smart Grid Technology and Applications</i>:</p> <ul> <li>Clearly unravels the evolving Smart Grid concept with extensive illustrations and practical examples.</li> <li>Describes the spectrum of key enabling technologies required for the realisation of the Smart Grid with worked examples to illustrate the applications.</li> <li>Enables readers to engage with the immediate development of the power system and take part in the debate over the future Smart Grid.</li> <li>Introduces the constituent topics from first principles, assuming only a basic knowledge of mathematics, circuits and power systems.</li> <li>Brings together the expertise of a highly experienced and international author team from the UK, Sri Lanka, China and Japan.</li> </ul> <p>Electrical, electronics and computer engineering researchers, practitioners and consultants working in inter-disciplinary Smart Grid RD&D will significantly enhance their knowledge through this reference. The tutorial style will greatly benefit final year undergraduate and master’s students as the curriculum increasing focuses on the breadth of technologies that contribute to Smart Grid realisation.</p>

<p>This book provides discussion on the fundaments of the Smart Grid concept and then describes the technologies that are required for its realisation. It allows the reader to engage with the immediate development of the power system and to take part in the debate over the future Smart Grid.</p> <p>The book opens with an overview on understanding the Smart Grid, and then is divided into three sections. Part 1 (Information and Communications Technologies') covers communication standards for the Smart Grid. Part Two discusses sensing, measurement, control and automation. Smart metering and demand side participation are described in detail, before distribution automation and the distribution management system. The last chapter of this section covers advanced transmission system operation. Part Three looks at power electronic and advanced components. First of all the topic of power electronics in power demand and supply is presented. Enabling technologies and advanced components are described last of all, giving a balanced view of Smart Grids.</p>
