摘要：
The single-unit prediction of offshore wind power cannot quickly predict the overall power of an offshore wind farm, and uneven fluctuations among units lead to poor quality of cluster power curves and low prediction accuracy. Therefore, this paper proposes an ultra-short-term power prediction model considering the spatial-temporal characteristics of offshore wind turbines. First, the improved dynamic time warping (DTW) algorithm is used to quantify the spatial-temporal characteristic similarity of offshore wind turbines and analyze the spatial-temporal characteristics of offshore wind turbines. Then, the Transformer model based on deep learning is used to establish the offshore wind power prediction model. Finally, the spatial-temporal characteristic similarity of offshore wind turbines and the bus position information are comprehensively considered to cluster the offshore wind turbines and conduct the ultra-short-term power prediction. The analysis of measured data of offshore wind turbines show that the proposed method can effectively quantify and measure the spatial-temporal characteristics of offshore wind turbines and timely predict the ultra-short-term power of offshore wind turbine groups. © 2022 Automation of Electric Power Systems Press.
