Role of IT and ICT in Smart Grid

The new era will be of Smart Grid in comparison with existing electricity grid.Smart grid is a combination of electricity grid and communication infrastructure. To give sustainable electricity supply, Smart grid connects with all the connected components to form a logical power network. To increase the effectiveness of power grid many sophisticated communication technologies have been recognized. These communication technologies increase the efficiency taken as a whole of electrical grid.This paper details the relevance and challenges of various communication technologies. Two major challenges have been found for implementing smart grid technology, first is standard inter operability and cognitive access to unlicensed radio spectrum. Paper also discusses the problems to implement smart grid communication on an evolutional path. Recent and future trends in Smart grid are elaborated. The paper provides the broad review of state of art research available on Smart grid communication
