The development of electricity smart grids at national level is one of the most discussed topics in Europe nowadays: the need of a transition towards a decarbonized economy, the depletion of non-renewable sources of energy and the need of urgent actions to combat the impact of climate change have indeed given this topic more and more relevance. Due to this, the smart grid field and specifically the distribution level of it results the one that is requiring the highest level of investments in Europe.
