6 FAQs about [Fault location in microgrid]
How to detect faults in a microgrid?
The proposed method is applied to detect, classify, and locate faults in a microgrid by using the one-terminal voltage and current data, measured at each distribution line of the microgrid. The measured currents and voltages are first filtered by a low-pass Butterworth filter to remove higher order harmonics.
