Concerning the Sustainability of Smart Grids: A critical analysis of the sustainability of current Smart Grid models and on indicators of Smart Grid sustainability assessment

摘要

There is currently no generally accepted definition of Smart Grids, especially on what is expected to make them smart and how. On the other hand, the general assumption about Smart Grids implies the development of power networks toward more efficient, greener and sustainable systems. In this article, we present the intrinsic limitations of this view, showing how any aim for a future sustainable energy system will require analyses considering the multidimensional structure of the problem, including the integrated dynamics of different energy sources and carriers. The aim of this paper is to present the case for the development and conceptualization of a smarter and more comprehensive system known as Smart Energy Networks. We also put forward a set of indicators that we believe could aid in assessing the sustainability of smart grids and follow progress toward the development of a more sustainable energy regime.
