Sustainable Energy, Grids and Networks, 2021 Abstract The behavior of constant power loads is known to be a potential cause of instability in DC microgrids. This issue is addressed by the DC microgrid stabilizer proposed in this paper. It relies on active stabilization through power electronic control by introducing a virtual positive resistance to counteract the negative incremental resistance
