DATA DRIVEN TIME ATTENTION CONVOLUTION WIND POWER PREDICTION MODEL

Because wind power is greatly affected by meteorological characteristics, and ther wind energy has strong volatility and intermittence, so that fast and accurate wind power prediction becomes a difficult problem. Therefore, a data-driven time attention convolution network wind power prediction method is proposed. Firstly, the data from the wind turbine and SCADA system are cleaned. Then the Temporal convolutional network which can be calculated in parallel is adopted, and the attention mechanism is added to highlight the influence of key features, so that the training speed and prediction accuracy of the model are effectively improved. Experimental results show that compared with other methods, the proposed method can reduce data noise more accurately, and has higher prediction accuracy and faster training speed.
