Chopperless Fault Ride-Through Control for DC Microgrids [PDF]
IEEE Transactions on Smart Grid, 2021 The dc microgrid should remain connected to the ac utility grid to support the grid stability during faults. However, the bidirectional power flow between the utility grid and the dc microgrid will cause either high-voltage or low-voltage faults at the dc bus.
