The transient instability mechanism and stability‐enhanced LVRT control for VSC riding‐through severe grid voltage sag

open access: yesIET Renewable Power Generation, 2023
As the grid‐connected interface device of wind and photovoltaic power generation, the voltage source converter (VSC) must pass the low voltage ride‐through (LVRT) test. However, existing literature demonstrates that under weak grid conditions, there is a
