Enel grid digitalization through multifunctional control and protection devices

Abstract

This paper addresses the challenge of distribution grid digitalization starting from the HV/MV substation, by presenting the Enel Global Infrastructure and Networks strategy.Enel Global Infrastructure and Networks (Enel GI&N) is a business division of Enel group, that is managing, through local distribution system operators (DSOs), more than 2.2 million kilometers of power lines in Argentina, Brazil, Chile, Colombia, Italy, Peru, Romania and Spain.This strategy is based on the introduction of multifunctional control and protection devices, extended interoperability along the distribution grid (by using IEC 61850) and high-speed communication (by including the LTE).This approach was tested in the Enel smart grid laboratories and it was validated in large scale implementations.
