LVRT and Stability Enhancement of Grid-Tied Wind Farm Using DFIG-Based Wind Turbine
, 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 ...
