Energy, the electrical power in particular, has been the most crucial and the resource always in scarcity in India and proving itself as a major bottleneck. Therefore, India has been transforming legacy conventional non-smart non-intelligent unidirectional electrical power grids into modern smart grids which are bidirectional and intelligent in nature by leveraging ICT, IoTs, e-Governance and e-Democracy. Smart grids are likely to serve as energy backbones of smart cities and involve high interactive participation of citizens in energy management, based on humanitarian and customer centric approach. Different types of Prosumers (Producers + consumers), their different energy requirements at different timings, different types of energy resources and their switching feasibilities conside...

Hence, smart city development is in fact, the transformation of approach in their futuristic contexts towards responsibilities, interests and rights of all its stakeholders; such as citizens, government, administration, services, utilities, etc. Globally, consistent focus for financial growth and quality of life has ultimately resulted into unprecedented rise in consumption of electrical energy. Electrical power management in India has become a critical issue with rising population, increasing life expectancy, economic growth and, more importantly, due to vibrantly changing and difficult to predict weather. Electrical power supply has always been a resource in deep scarcity in India, so 24 * 7 electricity is an issue causing concern. Efficient decision-making at different levels rely upon reliable availability o...
