Smart grids are electricity networks that can intelligently and dynamically integrate the actions of all users connected to them — those who produce energy, those who consume energy, or those who do both — in order to provide electricity efficiently, sustainably , economically and safely. Smart grids incorporate digital technology into their traditional design to facilitate the two-way exchange of energy and information. They do this thanks to the internet, information and communication technologies, control systems and modern IT and home automation applications. A smart grid is therefore capable of meeting the electricity demand of citizens and any events that come up. Smart grids are capable of integrating renewable installations of various sizes and, thanks to their bidirectional nature, the user can be both a consumer and a producer: they can generate energy and sell it to industrial or commercial users.
