| The response of the wind-storage combined power station to the grid frequency means that the station adjusts its own wind turbine output and the charge and discharge arrangement of the energy storage system according to the electricity price and the excitation signal to adjust the grid frequency. Firstly, the SVM regression algorithm and the frequency response service price are introduced. Then, the impacting factors, economic benefits and costs and the decision making of frequency re-sponse service of the wind-storage combined power station are studied. Based on the SVM regression algorithm, the frequency response model of the wind-storage combined power station is estab-lished, and the selection of input and output factors of the model is provided. Finally, the study cases validates the proposed model.
