Synchronverters With Fault Ride-Through Capabilities for Reliable Microgrid Protection During Balanced and Unbalanced Faults

IEEE Transactions on Sustainable Energy
Synchronverters are inverters that provide damping and inertia, similar to synchronous generators. Like traditional inverters, synchronverters are adaptable to the microgrid's operation modes.

Fault Current Unified Calculation Method for Whole Process Fault Ride-Through of DFIG-Based Wind Farms

IEEE Transactions on Smart Grid
The present inaccurate fault current calculation, due to the incomplete consideration of whole process operation stages of fault ride-through (FRT) of DFIG-based wind farms (WFs), has a distinct impact on the safe operation of local power grid. To tackle

Fault Current Suppression for the Fault Ride-Through of Triple-Active-Bridge Converters

IEEE transactions on industrial electronics (1982. Print)
The fault ride-through (FRT) capability is an important ancillary service for power converters in dc power distribution systems. Despite extensive research, the triple active bridge converter (TABC) has been perceived as lacking FRT capability due to the

Control Solution to Over-Modulation of DFIG Converter for Asymmetrical Fault Ride Through

IEEE Transactions on Sustainable Energy
This letter proposes a control solution to mitigate the problem of converter over-modulation in doubly fed induction generator (DFIG)-based wind turbine generators (WTGs). Overmodulation is a critical reason in failing to ride through asymmetrical faults
