DGFACTS comparative in wind power to solve LVRT requirements
This article compares the results recorded in the connection of three types of DGFACTS (DSTATCOM, DVR, UPQC) to a wind farm equipped with wind turbines with squirrel-cage induction generators, in order to test the response to voltage dips due to single-phase short circuit and two phase short circuit, because this type of asymmetric faults is one of the

Nonlinear Control-Based Modified BFCL for LVRT Capacity Enhancement of DFIG-Based Wind Farm
High penetration of wind power into existing grid can be attributed largely to the doubly fed induction generators (DFIG). However, their sensitive nature to the grid faults has created concern for their mass integration into the existing power system ...

An Enhanced LVRT Scheme for DFIG-based WECSs under Both Balanced and Unbalanced Grid Voltage Sags
Due to the latest grid codes, wind energy conversion systems (WECSs) are required to remain connected to grid under grid voltage sags and supply reactive power into the grid. So, this paper proposes an enhanced scheme to improve low-voltage ride through (

Optimization Strategy of Wind Power Curtailment Under LVRT Operation
A novel wind power curtailment optimization method considering low-voltage ride through (LVRT) operation is developed. The reserve capacity of wind generation for reactive power output is necessary to ensure the proper operation of a wind power plant (WPP) when a voltage drop occurs.
