Novel Frequency Control Technologies for Wind Turbines Based on Modified Gaussian Curve Settings

This paper concentrates on the frequency control technologies by WTs. Especially, stepwise inertia control (SIC)– related controls were discussed, and a modified Gaussian power curve- based control has been developed. The inspiration of this control method from Gaussian curves, which adjusts the shape characteristics of the Gaussian curve by tuning the associated parameters to achieve frequency regulation by WTs. When a frequency event occurs, WTs support an additional power immediately and then follow a reference power output based on the modified Gaussian curve equation. This study employed the user-defined model functionality of PSS/E, and an actual Taiwan Power Company (Taipower) system was used to verify the feasibility of the proposed control methods for WTs.
