How to detect fault in a microgrid using mathematical morphology and recursive least-square?

This paper proposes fault detection and location in a microgrid using mathematical morphology (MM) and recursive least-square (RLS) methods. MM is used to detect and classify the fault in a microgrid. The features of the fault current waveform captured by using MM operator and compare it with the threshold for fault detection and classification.

Can a deep transfer learning model detect short-circuit faults in DC microgrids?

The lack of fault data is the major constraint on data-driven fault detection and isolation schemes for DC microgrids. To solve this problem, this paper develops an adversarial-based deep transfer learning model that can detect and classify short-circuit faults in DC microgrids without using historical fault data.

How is fault location determined in microgrids using mm and RLS methods?

This paper proposes fault detection and location in microgrids using MM and RLS methods. An MM operator has been used to detect and classify the fault. The fault location estimation is obtained through the RLS method, which works directly on voltage and current samples acquired at one-terminal of the MV line segment.

Does a dc microgrid have fault-like features?

The principle of the proposed TL scheme is to extract fault-like features from normal operating data. For this reason, those operating disturbances that perturb DC microgrids in similar ways to faults are the focus of this study. In this section, the current features in a DC microgrid during a fault and such a non-fault disturbance are analyzed.

Why is data-driven fault detection a major constraint for DC microgrids?
