摘要
本研究之目的在於使用迴歸與類神經網路法進行風力發電預測。在NAR (Nonlinear Autoregressive) 模式下,將原始資料拆解並去除部分之後,可有較佳之預測結果,但須同時考慮去除之資料與原始 數據之比例,尤其是小型風機;在NARX (Nonlinear Autoregressive with External Input)模式下,則無 需刪除資料亦可改善預測之結果。本研究接著應用所提出之預報系統至MW等級之風場進行案例分 析。計算之結果顯示,使用NARX模式結合數據拆解前處理程序時,可獲得較佳之結果,而採用小 波轉換法處理數據後,對於預測準確度沒有明顯的影響。

The purpose of this study is to conduct the wind power prediction by the regression and neural network methods. Results show that smaller errors are achieved with more deleted data set in the Nonlinear Autoregressive (NAR) model. However, the ratio of the deleted data and raw data should be considered simultaneously, especially for the small wind turbine. In the case using Nonlinear Autoregressive with External Input (NARX) model, additional decomposed data set is employed, and the improvement is still achieved without the alteration of raw data. The performance of the proposed prediction model on the MW scale wind farm is also investigated. Results show that better performance is obtained using the NARX model combined with the decomposed data sets, and the resulted mean absolute percentage error (MAPE) is less than 5%. There is no obvious improvement (< 1%) in the prediction by using the method of wavelet transformation.
