Fault Ride Through in DC Microgrid with Faster Recovery

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
Breaking of fault current in dc microgrid has been a challenge due to lack of dc current zero crossing. The fault current in case of pole to pole fault is high and even higher in the presence of multiple generators as all the generators feed current to the fault. This results in very high current in the faulted line. Clearing such high fault current is

A DC Solid-State Transformer With DC Fault Ride-Through Capability

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
This paper investigates a dc solid state transformer (DCSST) with dc fault ride-through (FRT) capability for medium voltage dc (MVDC) systems. The fault ride through requirement for DCSST in dc gird is investigated. Short circuit fault clearance on the medium voltage (MV) side is realized by introducing full bridge converters with cascaded dc converter

An enhanced MMC topology with DC fault ride-through capability

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
High-voltage direct current system using modular multilevel converter (MMC-HVDC) is a potential candidate for grid integration of renewable energy over long distances. The dc-link fault is an issue MMC-HVDC must deal with. This paper proposed an enhanced MMC topology with dc fault ride-through capability.

Fault Ride Through for a DC ring bus microgrid

2016 International Conference on Energy Efficient Technologies for Sustainability (ICEETS), 2016
DC microgrid is gaining more prominence due to the development of renewable resources that generate DC output and also due to the increasing use of DC in end-user equipments. Also with DC system, connection of backup energy storage and small size generation is easier to realize. For any system, disconnecting a part of the system during temporary faults

A DC Solid State Transformer with DC Fault Ride-through Capability

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
This paper investigates a DC solid state transformer (DCSST) with DC fault ride-through (FRT) capability for medium voltage DC (MVDC) systems. The ability of short circuit fault clearance on the medium voltage (MV) side can be promoted with a suitable control scheme by introducing one or several full bridge converters to the cascaded DC converter ...
