Generation energy-efficiency by Smart grid Data centers distributed & ICTs sustainability

Abstract

Smart grid has modernized the way electricity is generated, transported, distributed, and consumed byintegrating advanced sensing, communications, and control in the day-to-day operation of the grid. Electricity is a coreutility for the functioning of society and for the services provided by information and communication technologies(ICTs). Several concepts of the smart grid, such as dynamic pricing, distributed generation, and demand management,have significantly impacted the operation of ICT services, in particular, communication networks and data centers.Ongoing energy-efficiency and operational expenditures reduction efforts in communication networks and data centershave gained another dimension with those smart grid concepts. In this paper, we provide a comprehensive survey onthe smart grid-driven approaches in energy-efficient communications and data centers, and the interaction betweensmart grid and information and communication infrastructures. Although the studies on smart grid, energy-efficientcommunications, and green data centers have been separately surveyed in previous studies, to this end, research thatfalls in the intersection of those fields has not been properly classified and surveyed yet. We start our survey byproviding background information on the smart grid and continue with surveying smart grid-driven approaches inenergy-efficient communication systems, followed by energy, cost and emission minimizing approaches in datacenters, and the corresponding cloud network infrastructure. Through a communication infrastructure, a smart grid canimprove power reliability and quality to eliminate electricity blackout.
