The substantial increase in new integration of wind power has required changes in grid codes to ensure grid security. Providing low voltage ride through (LVRT) protection helps to sustain the transient conditions without tripping and supports its recovery post-fault. The grid codes for LVRT capability in countries with substantial wind capacity are surveyed in this paper. The challenges that arise, endangering the grid security due to the non-implementation of these grid codes in the wind turbines (WT) which were pre-installed before the mandatory grid code was established is rarely a topic focused in literature. The LVRT capability requirement as per the wind turbine type classification is elucidated. The challenges due to enhancement and upgradation of technology include financial constraints for additional LVRT fittings, planning and renovation. Discussion and prognosis on the challenges provide direction for investigation and research. © 2020 John Wiley & Sons Ltd
