Transient Stability Analysis and Enhancement of Renewable Energy Conversion System During LVRT
IEEE Transactions on Sustainable Energy, 2020Grid-connected renewable energy conversion systems (RECSs) are usually required by grid codes to possess the low voltage ride through (LVRT) and reactive power support capabilities so as to cope with grid voltage sags.

A Multi-Machine Equivalent Model of a Wind Farm Considering LVRT Characteristic and Wake Effect
IEEE Transactions on Sustainable Energy, 2022The wind turbines (WTs) present in a wind farm (WF) are subjected to varying wind speeds owing to the wake effect. Additionally, the response of a WF is also affected by the low voltage ride-through (LVRT) characteristic imbibed in each doubly-fed ...

Advanced LVRT Control Scheme for Offshore Wind Power Plant
IEEE Transactions on Power Delivery, 2021Offshore wind farms (OWF) are being rapidly integrated to the power systems, which can be primarily attributed to saturation of the mainland onshore area, and high wind speed in offshore sites. However, to maintain stable grid operation, OWFs are required to comply with Low Voltage Ride Through (LVRT) capability.

Nowadays wind turbines are generally required to offer ancillary services similar to those provided by conventional generators. One of the most important services wind turbines must offer is to stay connected to the grid in fault situations delivering the reactive current specified in the recent grid codes.

LVRT-DGFACTS devices in wind farms
2011 International Conference on Power Engineering, Energy and Electrical Drives, 2011This article compares the results recorded in the connection of three types of DGFACTS (DSTATCOM, DVR, UPQC) to a wind farm in order to resolve the issues of LVRT requirements on wind farms equipped with wind turbines with squirrel-cage induction generators.

Similar to emerging regional grid codes, the recently approved IEEE 2800 Standard mandates that inverter-based resources (IBRs) generate negative-sequence current during low-voltage ride-through (LVRT) conditions. The 2800 Standard requires that the IBRs'

LVRT-retardation-device for decentralized power plants
2014 Electric Power Quality and Supply Reliability Conference (PQ), 2014During fault events in the electrical power grid nearby a synchronous generator, the rotor speed of the machine is increased, because dissipated power is below generated power. This may cause high rotor angle excursions and hence the machine to lose synchronism with the power grid.

Mechanical Stress Comparison of PMSG Wind Turbine LVRT Methods
IEEE Transactions on Energy Conversion, 2021The grid code for renewable energy is increasingly strict to circumvent issues with grid stability and reliability. One grid code standard that is enforced for most modern variable speed wind turbines (WTs) is the low-voltage ride-through (LVRT) criteria, where WTs are to be grid-connected during voltage dips.
