Advances in Computer and Materials Scienc ResearchAs the share of wind power in the power generation structure increases, the demand for effective frequency regulation using wind turbines also grows. Wind turbines typically participate in frequency regulation by reducing rotor speed. However, extended operation at low speeds can lead to efficiency losses, which necessitate measures to disengage from ...
