Blackstart and Fault Ride-Through Capability of DFIG-Based Wind Turbines
IEEE Transactions on Smart Grid, 2023Grid-forming wind turbines must be able to re-energize transmission branches, motor loads, unbalanced loads, and power electronics loads following a blackout. Further, they must ride through faults that can arise during restoration.

Grid-Forming Control With Current Limitation for MMC Under Unbalanced Fault Ride-Through
IEEE Transactions on Power Delivery, 2021This letter proposes a grid-forming control method for Modular Multilevel Converter (MMC) with AC-side current limitation capabilities under fault ride-through scenarios (balanced and unbalanced faults).

Fault ride through augmentation of microgrid
2015 International Conference on Technological Advancements in Power and Energy (TAP Energy), 2015The modern grid codes for fault ride through specifications in transmission and distribution grids specify that Distributed Generation (DG) must remain connected to the grid even at voltages well below the nominal voltage. This is contrary to the traditional approach, whereby the power plants were not required to stay connected.

Wind-Turbine Fault Ride-Through Enhancement
IEEE Transactions on Power Systems, 2005Fault ride-through specifications listed in modern transmission and distribution grid codes specify that wind-turbine generators (WTGs) must remain connected to electricity networks at voltage levels well below nominal. Achieving reliable operation at greatly reduced voltage levels is proving problematic.

IEEE Transactions on Sustainable Energy, 2022
Inverter-interfaced renewable energy sources (IIRESs) are typically controlled during fault conditions to meet fault ride-through (FRT) requirements, e.g., reactive current generation (RCG) requirements specified by grid codes (GCs).

The current-limiting inductors (CLIs) are commonly used to suppress DC fault current to safely trip DC circuit breakers in MMC-HVDC systems, but it significantly jeopardizes DC dynamics and causes instantaneous power mismatch between AC and DC sides of ...

Fault Ride-Through Capability Enhancement by using Fuzzy Control
Power and Energy Systems, 2012This paper proposes a fuzzy controller for improving Fault Ride-Through (FRT) capability of Doubly Fed Induction Generator (DFIG) based Wind Turbines (WTs). The controller is designed in order to compensate the voltage at the Point of Common Coupling (PCC) by regulating the reactive and active power generated by WTs simultaneously.

Fault Ride-through Testing of Wind Turbines
Wind Engineering, 2006Grid codes concerning low-voltage fault ride-through capabilities of wind turbines are not (yet) harmonized, varying from country to country. Full-scale field testing of wind turbines with respect to all such codes may therefore not be practical. IEC 61400-21 is currently under revision, and the last committee draft (CD 2006) presents a standardized ...
