Abstract
An invention offers a broadband oscillation suppression method and apparatus for wind-storage combinations. The method involves several steps: first, acquiring the operational state of a wind-storage station system at an initial moment. Next, different control variables and this operational state are input into a prediction model to identify two wind turbine frequencies and their corresponding operational states for a subsequent moment. Then, these control variables and the new operational states are used in the prediction model to derive wind turbine frequencies for a third moment. Finally, a control variable from the initial moment, linked to the wind turbine frequency with the lowest value function among the two frequencies at the third moment, is selected as the final control variable for managing the wind turbine and energy storage system. The method effectively reduces regulation costs during broadband oscillation suppression, enhancing the operational safety and stability of the wind-storage station.
