Voltage Fault Ride-Through Operation of Solar PV Generation
2021Solar PV (SPV) resource-based distributed generation units with installations ranging from few kW to hundreds of MW are an immediate solution to meet the ever-increasing energy needs. Voltage fault ride-through (FRT) operation is an emerging requirement for SPV units that ensures reliable operation of the utility grid.

Wind-turbine fault ride-through enhancement
2006 IEEE Power Engineering Society General Meeting, 2006Summary form only given. Fault 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.

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 ...

Fault Current Hierarchical Limitation Strategy for Fault Ride-Through Scheme of Microgrid
IEEE Transactions on Smart Grid, 2019With the growing penetration of grid-connected microgrids (MGs), utility grid (UG) faces the challenge of high-level fault current during fault ride-through (FRT) of MGs. To tackle this challenge, a fault current hierarchical limitation (FCHL) strategy is proposed, which consists of four levels: 1) fault current primary limitation control (FCPLC) is ...

Fault ride-through enhancement of wind turbines in distribution networks
Journal of Ambient Intelligence and Humanized Computing, 2012This paper proposes a fuzzy controller for improving fault ride-through (FRT) capability of doubly fed induction generator based wind turbines (WTs). The controller is designed in order to compensate the voltage at the point of common coupling by regulating the reactive and active power generated by WTs simultaneously.

An enhanced MMC topology with DC fault ride-through capability
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013High-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.

Low voltage fault ride through control in MMC-HVDC
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017Modular multilevel converters (MMCs) are the latest converter topology for the high voltage high power applications like the high voltage dc (HVDC) transmission. This paper presents the response of an MMC-HVDC converter during grid faults. Recent grid code requirements specify reactive current injection during low voltage fault conditions and negative ...
