Task of Energy Router in Smart Grids

Many buzzwords concerning the problematic of energy production and its effective (smart) utilization in industry as well as in households - like Smart Grid, Big Data, Industry 4.0, Energy Router, Green Energy etc. - are often used in many different meanings or even only for making one's idea more attractive. Nevertheless, their definitions aren't united or they don't express the essence in their entirely. The aim of this paper isn't to define some of the buzzwords; however, it tries to explain what is really a so called energy router and why is it spoken about in the context of existing and to the near future planned system of electrification in the central Europe. Some kinds of energy storage are integral to the modern grid. The short overview of energy storage devices is presented at the end. This text should make the understanding of the problematic in wider extent easier.
