Fault Ride-Through Capability of Voltage-Controlled Inverters
IEEE Transactions on Industrial Electronics, 2018An 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 in DC Microgrid with Faster Recovery
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020Breaking 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

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.

Fault Ride Through and Fault Current Management for Microgrids
2020Over the recent years, the distributed energy resource (DER) generation and integration with utility grid became the most widely used worldwide. Thereon, the integration of distributed energy resources to the power grid and their dynamics during grid faults had become a critical issue in the new grid code requirements. In line with this, the fault ride

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 Criteria Development
2014Wind energy integration into transmission systems has been accelerated by establishing robust grid codes relevant to the network. Fault Ride-Through (FRT) criteria is one of them, which requires generation to stay connected to transmission system under certain operational voltage envelope.

Fault Ride-Through trip curves
2012 IEEE Power and Energy Society General Meeting, 2012Over the past decade, new requirements have been proposed and implemented for Fault Ride Through, including a proposed NERC standard that would impose fault ride through requirements on all generation. Most existing fault ride through curves are used in the wind industry.

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 ...
