Planning and protection of DC microgrid: A critical review on recent developments
Engineering Science and Technology, an International Journal, 2023 Nowadays, direct current (DC) microgrid is gaining importance due to the wide utilization of DC loads, integration of solar photovoltaic (PV) and energy storage devices, and no frequency and reactive power control issues. However, planning and protection

A novel protection strategy for DC microgrid considering communication failure
Energy Reports, 2023 DC microgrid has become an important part of supporting “carbon peaking, carbon neutralization” and building a low-carbon energy system. However, the short-circuit current of the DC microgrid rises rapidly and has a great impact, threatening the normal ...

Adaptive distance protection for microgrids [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 Due to the increasing penetration of distributed generation resources, more and more microgrids can be found in distribution systems. This paper proposes a phasor measurement unit based distance protection strategy for microgrids in distribution system. At the same time, transfer tripping scheme is adopted to accelerate the tripping speed of the relays
