Under complex grid conditions, the voltage usually has an imbalance, low order harmonics, and a small of DC bias. When contains harmonics amount bias component, inverter's output current cannot meet connection requirements, there is three-phase imbalance in control strategy common VSG under unbalanced voltage. A theoretical analysis non-ideal power grids carried out, operating conditions propos...

DC microgrids have gained a lot of interest recently due to increasing dc loads such as electric vehicles and the penetration renewable energy sources (RESs). However, face challenges concerning bus voltage fluctuations, which severely impact system stability when subjected uncertainties load RESs. This paper focuses on maintaining DC-bus through control for islanded microgrid using concept cas...
