Power system protection is crucial for maintaining the stability and reliability of the electricity
grids and preventing costly disruptions. Conventional protection devices operate on pre …

Micro-grid protection presents great technical challenges to utility company engineers.
Several protection schemes have been developed towards a reliable operation on these …

Smart networks such as active distribution network (ADN) and microgrid (MG) play an
important role in power system operation. The design and implementation of appropriate …

Distribution networks are operated in different conditions and the traditional protection
systems might not be proper for all available operation conditions by using directional …

Electric power distribution systems have been submitted to major changes related to the
integration of communication infrastructure and new technologies such as distributed …

When a transformer is in a long-term heavy load operation state, the oil temperature reaches
the alarm temperature; if a slight fault occurs inside the transformer, traditional inverse time …

Open conductor faults are causing socioeconomic problems worldwide owing to fires
caused by arc generation and increased risk of human electric shock. Also, the recent …

We propose a hierarchical approach for detecting open conductor faults (OCFs) at the
feeder remote terminal unit (FRTU) level and performing the final determination and location …

Due to the characteristics of multiple points, complex users, and frequent changes, the
topological relationship of the low-voltage distribution network is often in an inaccurate …

With the increased penetration of distributed generators (DGs) in the distribution system, the
protection schemes based on standard inverse time characteristics are unsuitable as DGs …
