How Smart is the Grid?
share
Ancient Romans called 'urbs' the set of buildings and infrastructures, and 'civitas' the Roman citizens. Today instead, while the society is surfing the digital tsunami, 'urbs' and 'civitas' tend to become much closer, almost merging, that we might attempt to condensate these into a single concept: 'smart grid'. Internet of things, artificial intelligence, blockchain, quantum cryptography is only a few of the paradigms that are likely to contribute to determining the final portrait of the future smart grid. In this article, a systematic review of the emerging paradigms is presented, identifying intersectoral synergies and limitations with respect to the `smart grid' concept. Further, a taxonomic framework for assessing the level of sustainability of the grid is proposed. Finally, from the scenario portrayed, a set of issues involving engineering, regulation, security, and social frameworks have been derived in a theoretical fashion. Findings are likely to suggest the urgent need for multidisciplinary cooperation to wisely address engineering and ontological challenges gravitating around the smart grid concept.
