The spread of smart city and power quality requirements

In view of the structural changes that the electrical system is living in recent years, deriving for the most by the increasing penetration of non-programmable renewable distributed in the territory, it feels more and more to speak about Smart City and Smart Grid for greater flexibility, efficiency and reliability of networks. In recent decades, major changes in production systems, electricity transmission, both from the technological point of view that regulatory and economic have been. Energy efficiency, energy conservation and use of renewable sources are elements, very important, that could determine this change, for example the improvement that can be done through the relationships between smart city, smart grid and power quality (PQ). The Smart City brings many new challenges on PQ; these should result in the introduction of new technology through intelligent use of them. The scope of this paper is to give an overview of the smart city development, observing a possible correlation with the power quality.
