ABSTRACT = {Due to the frequent changes of wind speed and wind direction, the accuracy of wind turbine (WT) power prediction
using traditional data preprocessing method is low. This paper proposes a data preprocessing method which combines POT with DBSCAN (POT-DBSCAN) to improve the prediction efficiency of wind power prediction model.
Firstly, according to the data of WT in the normal operation condition, the power prediction model of WT is established based on the Particle Swarm Optimization (PSO) Arithmetic which is combined with the BP Neural Network
(PSO-BP). Secondly, the wind-power data obtained from the supervisory control and data acquisition (SCADA)
system is preprocessed by the POT-DBSCAN method. Then, the power prediction of the preprocessed data is
carried out by PSO-BP model. Finally, the necessity of preprocessing is verified by the indexes. This case analysis
shows that the prediction result of POT-DBSCAN preprocessing is better than that of the Quartile method. Therefore, the accuracy of data and prediction model can be improved by using this method.},
