Coordinated Control of an Ultracapacitor Bank and a Variable-Speed Wind Turbine Generator for Inertial Response Provision During Low and Above Rated Wind Speeds

There is a risk of wind turbine stalling when virtual inertial response is provided during low wind speeds due to the turbine speed reduction. Therefore, it is wise to consider minimum rotor speed limitation during inertial response provision so it can be suspended in time to avoid stalling. However, since low wind speed conditions can happen fairly often, the capability for inertial response is lost which may be crucial for scenarios with high...
