Protective Systems in DC Microgrids
, 2019 The aging power system causes to several grid problems such as intermittency, power quality issues, and blackouts since a few decades. Therefore, the power infrastructure requires serious troubleshooting studies in a wide manner. The distributed generation and integration of large photovoltaic (PV) plants to the existing utility have led to intensive ...

Protection of Low-Voltage DC Microgrids
IEEE Transactions on Power Delivery, 2009 In this paper, a low-voltage (LV) DC microgrid protection system design is proposed. The LV DC microgrid is used to interconnect distributed resources and sensitive electronic loads. When designing an LV DC microgrid protection system, knowledge from existing DC power systems can be used.

Coordination of MMC converter protection and DC line protection in DC grids
2016 IEEE Power and Energy Society General Meeting (PESGM), 2016This paper studies the coordination of MMC converter protection and DC line protection in DC transmission networks. To quickly isolate a DC line fault, hybrid DC circuit breaker is connected at each end of every DC transmission line. DC line protection based on measuring derivative of DC voltage is employed to timely trip faulted DC line only. The goal
