Fault Ride-Through Capability of Voltage-Controlled Inverters

IEEE Transactions on Industrial Electronics, 2018
An auxiliary voltage controller is proposed for the fault ride-through (FRT) control of voltage-controlled inverters used in distributed energy resources. The proposed auxiliary controller can be added to different existing voltage control strategies with minimum or no need to alter the original structure of the voltage controller.

Fault ride through augmentation of microgrid

2015 International Conference on Technological Advancements in Power and Energy (TAP Energy), 2015
The 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, 2005
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 Capability Enhancement by using Fuzzy Control

Power and Energy Systems, 2012
This 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.
