An electrical grid that has a variety of operations and energy measures such as energy efficiency and renewable energy resources, advanced metering infrastructure and circuit breakers integrated with home control is termed as a smart grid. Reliability, flexibility in network topology, efficiency, and sustainability are some of the features of smart grids. They have applications in a wide variety of fields such as manufacturing, telecommunications, integrated communications, sensing and measurement, smart power generation, etc. The two important aspects of smart grids are electronic power conditioning, and control of the production and distribution of electricity. This book outlines the theories and applications of electric machines for smart grids in detail. The various studies that are constantly contributing towards advancing technologies and evolution of this field are examined in detail. This book is a vital tool for all researching and studying this field.
