Considering the LVRT performance of the new energy station and the structural characteristics of the Henan power grid, aiming at the voltage stability and low voltage problems of the Henan power grid, this paper analyzes the influence of adjusting the key parameters of the new energy LVRT model on the stability characteristics of the Henan power grid. Then combined with regional characteristics, this paper analyzes the selection principle of LVRT control performance and makes simulation verification. The result shows that: On the basis of the characteristics of the regional power grid, the control parameters of new energy LVRT are optimized in different region, the principle of reactive power priority is adopted for the new energy stations in northern and western Henan, and the principle of active power priority is adopted for the new energy stations in the Middle East and southern Henan. The new energy station can reasonably provide active or reactive power support during the failure of the power grid, alleviate the problem of power flow shift or voltage stability during the failure, and improve the stability of the power grid.
