Smart Grid & Integration of Renewable Energy Resources Smart Grid & Integration of Renewable Energy Resources

What is Smart Grid ? w The Smart Grid is a combination of hardware, What is Smart Grid ? w The Smart Grid is a combination of hardware, management and reporting software, built atop an intelligent communications infrastructure. w In the world of the Smart Grid, consumers and utility companies alike have tools to manage, monitor and respond to energy issues. w The flow of electricity from utility to consumer becomes a two-way conversation, saving consumers money, energy, delivering more transparency in terms of end-user use, and reducing carbon emissions.

What is Smart Grid ? w Modernization of the electricity delivery system so that What is Smart Grid ? w Modernization of the electricity delivery system so that it monitors, protects and automatically optimizes the operation of its interconnected elements – from the central and distributed generator through the high-voltage network and distribution system, to industrial users and building automation systems, to energy storage installations and to end-use consumers and their thermostats, electric vehicles, appliances and other household devices. w The Smart Grid in large, sits at the intersection of Energy, IT and Telecommunication Technologies. 3
