Abstract: In plan tracking mode,a coordinated control method for the wind storage system is proposed to maximize the economic benefit. Firstly,a wind-storage system plan tracking control model is established based on ultra-short-term power forecast with the objective function of maximizing the total operation profits. Then,an ultra-short-term power prediction correction model is established based on wavelet transform and Sequence to Sequence（seq2seq）. Ultra-short-term power prediction data and historical actual power data are used to correct the power prediction error. Finally,the plan tracking control model and the ultra-short-term prediction error correction model are combined with each other,and then a plan tracking control strategy for wind-storage system is proposed,considering the ultra-short-term forecast error. The simulation results show that the proposed strategy can significantly improve the tracking accuracy of wind power schedule,which increases the operation economy of the wind-storage system and promotes the renewable energy consumption.
