        摘 要:為實(shí)現(xiàn)不規(guī)律、波動性大、不確定性的電力負(fù)荷數(shù)據(jù)高精度預(yù)測,提出了一種使用小波包分解(WPD)與麻雀搜索算法(SSA)來優(yōu)化支持向量回歸(SVR)的短期負(fù)荷預(yù)測方案。該方案使用 WPD 將原始負(fù)荷序列分解成多個各異的小波動分量,將分解后的各組數(shù)據(jù)分別輸入 SSA 優(yōu)化后的 SVM 模型,并將得到的多個各異的小波動分量分別經(jīng)模型預(yù)測出的結(jié)果進(jìn)行相加得到最后取得的預(yù)測結(jié)果。結(jié)果表明:該方案能較好擬合整個測試集上的實(shí)際預(yù)測點(diǎn)位,適合于電力系統(tǒng)短期負(fù)荷的準(zhǔn)確預(yù)測,證實(shí)了該模型的有效性和優(yōu)越性。

        Abstract: To achieve high-precision prediction of irregular, highly volatile, and uncertain power load data, a short-term load forecasting scheme with using wavelet packet decomposition (WPD) and sparrow search algorithm (SSA) is proposed to optimize support vector regression(SVR). Firstly, WPD is used to decompose the original load into multiple distinct small fluctuation components. Then, each group of decomposed data is inputted into the SSA optimized SVM model. Finally, the obtained multiple distinct small fluctuation components are added up to the predicted results of the model to obtain the final prediction result. The results show that this scheme can well fit the actual predicted points on the entire test set, and is suitable for accurate short-term load prediction of the power system, confirming the effectiveness and superiority of the model.
        Key words: short-term power load forecasting; wavelet packet decomposition; sparrow search algorithm; support vector machine
