A Survey on Smart Grid Communication Infrastructures: Motivations, Requirements and Challenges Ye Yan, Yi Qian, Hamid Sharif, and David Tipper
This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination. IEEE COMMUNICATIONS SURVEYS & TUTORIALS, ACCEPTED FOR PUBLICATION 1 A Survey on Smart Grid Communication Infrastructures: Motivations, Requirements and Challenges Ye Yan, Yi Qian, Hamid Sharif, and David Tipper Abstract—A communication infrastructure is an essential emerging renewal distributed generator through transmission part to the success of the emerging smart grid. A scalable network and distribution system to industrial consumer and/or and pervasive communication infrastructure is crucial in both home users with their thermostats, electric vehicles, intelligent construction and operation of a smart grid. In this paper, we present the background and motivation of communication appliances [2]. A smart grid is characterized by the bi- infrastructures in smart grid systems. We also summarize major directional connection of electricity and information flows requirements that smart grid communications must meet. From to create an automated, widely distributed delivery network. the experience of several industrial trials on smart grid with It incorporates the legacy electricity grid the benefits of communication infrastructures, we expect that the traditional modern communications to deliver real-time information and carbon fuel based power plants can cooperate with emerging distributed renewable energy such as wind, solar, etc, to reduce enable the near-instantaneous balance of supply and demand the carbon fuel consumption and consequent green house gas management [3]. such as carbon dioxide emission. The consumers can minimize Many technologies to be adopted by smart grid have their expense on energy by adjusting their intelligent home already been used in other industrial applications, such as appliance operations to avoid the peak hours and utilize the renewable energy instead. -

The power efficient energy management and “level playing demand for electricity has been growing very fast during the last Field” competition and regulation decades with a high impact on global climate and environmental conditions. The answer is grid access of large amounts of Nowadays when discussing about smart grids, the smart Renewable Energy Sources (RES), e.g. wind and solar distribution system seems to have the highest priority in the technology. This, however, makes the power systems more grid development; however the other systems – smart complex and consequently changes the grid structure: the linear generation and smart transmission – have a similar energy chain, consisting of large centralized power plant with importance in order to efficiently drive the whole grid into a excellent control features (“power on demand”), is rapidly smart power system. When high investments for generation becoming a complex power matrix with Dispersed Generation systems are made to supply bulk power to the distribution (DG), of which many are installed on medium and even low level, the smart transmission system is essential to avoid voltage levels. Such a grid structure must be “Smart”. -

Europe's Supergrid
PROTECTING EUROPEAN CIVILISATION: EUROPE’S SUPERGRID Eddie O’Connor Marcos Byrne Introduction 1. What Europe will look like in 2050. I. What will our electrical demand be? II. How influential will rooftop solar and storage be? III. What effect will electric vehicles have on this demand? IV. How will the demand be met by renewables? 2. What Resources are available to meet this demand. I. Where will the main sources of generation be located? II. How can we access the areas of great potential? 3. How we can distribute this renewable energy. I. How do we interconnect countries with great wind and/or solar resources with those with weaker renewable resources? II.
