Grids are networks of transmission lines, substations and transformers that deliver electricity from power plants to homes or businesses. A smart grid is an electrical grid which involves a variety of operation and energy measures to automate and manage the increasing complexity and needs of electricity. These include advanced metering infrastructure, smart distribution boards and circuit breakers, renewable and energy efficient resources, and fiber broadband to connect and monitor the above. Some of the important features of smart grids are electronic power conditioning, and control of the production and distribution of electricity. It is typically focused on the technical infrastructure, but also implies a fundamental re-engineering of the electricity services industry. The book studies, analyses and upholds the pillars of smart grid technology and its utmost significance in modern times. There has been rapid progress in this field and its applications are finding their way across multiple industries. This book will help new researchers by foregrounding their knowledge in this branch.
