    Abstract

    Grid-forming (GFM) Inverter control has been regarded as essential for the transition to the renewable-based power system due to the robustness and stability issues. For the application of GFM control to wind turbines, many related studies are in progress and published. This paper proposes a low voltage ride-through (LVRT) strategy of GFM control on a permanent magnetic synchronous generator-based wind turbine considering the transient stability of DC-link voltage. The proposed strategy suppresses overcurrent through the virtual impedance method in transient conditions during fault. And Recovery Mode after fault clearing can improve the transient stability of DC-link voltage which is not an ideal DC source. For the verification of the proposed strategy, the case study was conducted using PSCAD/EMTDC.
