Design of a Microgrid with Low-Voltage Ride-Through Capability and Simulation Experiment [PDF]
Journal of Applied Mathematics, 2014 A microgrid with low-voltage ride-through capability is designed. The designed microgrid avoids operating in unplanned islanded mode during an asymmetric ground fault which occurs in the low voltage distribution network and supports fault recovery for distribution network.
