Data-driven Decoupling Evaluation Method of Wind Power Prediction Error
For the complexity of multi-link interaction in wind power prediction
this paper proposes a refined evaluation method for wind power prediction error. It aims to quantitatively analyze the effect of each key link of power prediction on the total prediction error by using numerical weather prediction
meteorological observation data
wind power operation data and other multi-source heterogeneous information. Firstly
the operation mechanism of wind power prediction is analyzed
the prediction process is divided into three key links
i.e.
numerical weather prediction
wind energy-power conversion modeling and prediction result correction. Secondly
based on the kernel density estimation
the segmented identification method is designed for wind power anomaly data
and a simplified model of wind resource-power characteristics is established. Finally
based on the multi-source operation data-driven in meteorology and electric power
a method for measuring equivalent error in each link of power prediction is proposed. The case results show that the proposed method can quantitatively evaluate the effects of each link on the power prediction error.
