In recent years, with the increasing of wind power development, the demand for low voltage ride‐through (LVRT) technology was proposed to ensure the safe and reliable operation of the power system. The key issue of LVRT strategy for doubly‐fed induction generator (DFIG) varies according to the network synchronisation modes. Firstly, the existed LVRT technologies when DFIG is connected to AC network are surveyed. Then relevant literatures about LVRT are summarised and analysed in regard to power surplus of two‐terminal system and DC voltage control of multi‐terminal system, respectively, when the wind farm is integrated with VSC‐high‐voltage direct current (HVDC). In the end, the coordinated control strategy of multi‐terminal VSC–HVDC system and LVRT technology for islanded system are prospected in this study.
