LVRT Test data analysis of converter‐interfaced wind turbines
The Journal of Engineering, 2019 Doubly Fed Induction Generator (DFIG) and Permanent Magnet Synchronous Generator (PMSG) are converter‐interfaced wind turbines, which have much more complex short circuit behaviour after grid voltage drops. The research on short circuit current contributions provided by the wind turbines is very important for power system planning and relay protection ...

LVRT and Stability Enhancement of Grid-Tied Wind Farm Using DFIG-Based Wind Turbine
Applied System Innovation, 2021 According to the grid code specifications, low voltage ride-through (LVRT) is one of the key factors for grid-tied wind farms (WFs). Since fixed-speed wind turbines with squirrel cage induction generators (FSWT-SCIGs) require an adequate quantity of ...

A novel decentralized inverter control algorithm for loss minimization and LVRT improvement
Electric Power Systems Research, 2023 Algorithms that adjust the reactive power injection of converter-connected RES to minimize losses may compromise the converters' fault-ride-through capability. This can become crucial for the reliable operation of the distribution grids, as they could lose valuable resources to support grid voltage at the time they need them the most.
