    摘 要 :為了確保電力系統(tǒng)的可靠運行與持續(xù)供電,準確的風電功率預測顯得尤為重要。提出了一種新的白鯊優(yōu)化算法-長短期記憶網(wǎng)絡 (WSO-LSTM) 模型,用于短期風電功率的預測 ;利用LSTM在自動學習 序列數(shù)據(jù)特征方面的優(yōu)勢,同時借助WSO的全局優(yōu)化策略對LSTM層的窗口大小及神經(jīng)元數(shù)量進行優(yōu)化。 通過標準性能指標,將WSO-LSTM的預測結果與實際功率以及現(xiàn)有模型的預測結果進行了對比,結果表明, WSO-LSTM能夠為歐洲 4 個風電場提供準確、可靠且穩(wěn)健的風電功率預測,預測精度平均提升了 20%~47%。

    Abstract: To ensure the reliable operation and continuous power supply of the power system, accurate wind power prediction is particularly important. This paper proposes a novel white shark optimization algorithm-long short-term memory network (WSO-LSTM) model for short-term wind power prediction. By taking advantage of the strengths of LSTM in automatically learning the features of sequential data, and with the help of the global optimization strategy of WSO, the window size and the number of neurons of the LSTM layer are optimized. Through standard performance indicators, the prediction results of WSO-LSTM were compared with the actual power and the prediction results of existing models. The results show that WSO-LSTM can provide accurate, reliable and robust wind power prediction for four wind farms in Europe, achieving an average improvement in prediction accuracy ranging from 20% to 47%.
    Key words: white shark optimization algorithm; long short-term memory network; wind power prediction; machine learning; feature extraction
