基于词嵌入注意力机制时间卷积网络的风电功率预测

WIND POWER PREDICTION BASED ON WORD EMBEDDING ATTENTION AND TEMPORAL CONVOLUTION

  • 摘要: 考虑到风电功率的随机性,准确预测风电功率比较困难,在此背景下尝试性地提出一种新的时间序列模型,称为词嵌入注意力时间卷积网络(Attention-WE-TCN-LSTM)。该模型主要包括词嵌入的TCN结构和注意力机制两部分。通过词嵌入的编码利用两种不同的注意力特征进行特征融合,从而在风电功率预测方面具有一定的预测能力。最后根据对比实验和消融实验,不仅证明了该模型相比于传统的时间序列模型具有一定的优势,还证明了其有效性。

     

    Abstract: Considering the randomness of wind power variation, it is difficult to accurately predict wind power generation. In this context, this paper tentatively proposes a new time series model called the Attention-WE-TCN-LSTM. This model mainly included two parts: the TCN structure of word embedding and attention mechanism. By utilizing two different attention features for feature fusion through word embedding encoding, a certain predictive ability was achieved. Based on comparative experiments and ablation experiments, it not only demonstrates that the proposed model has certain advantages compared with traditional time series models, but also demonstrates its effectiveness.
