Microgrids are the answer for a more sustainable, resilient and digital energy. This power system concept represents the evolution of the new electrical distribution based on distributed energy resources in commercial buildings and industrial plants. Within microgrid projects, there is a continuously increase of use cases where DC technology is used. Thanks to the contribution from the University of Genova, we will discover more on how the research is supporting this market trend, from simulations at labs to on-field applications. Common DC bus implementations, protection based on solid state innovations, advanced selectivity techniques are just few examples on how microgrid facilities leverage on DC solutions. As a result of this energy revolution, the current war from Tesla and Edison will come back as mainstream topic.
