Abstract :
Today, the architecture of electrical networks is evolving. Distributed dc generation from photovoltaic systems and small wind turbines, the possibilities offered by dc energy storage, the spread of smart grids, and the potential of high- and middle-voltage dc ensured by high-voltage power electronics, enable us to conceive new scenarios with respect to the presently dominating ac high-voltage energy transmission and distribution. But when and how did the latter system emerge?
