Ultra-short-term Prediction of Wind Power Based on Multi-location Numerical Weather Prediction and Gated Recurrent Unit
Numerical weather prediction (NWP) has an important impact on the accuracy of ultra-short-term prediction models for wind power. In order to make full use of the NWP information
considering the spatial correlation of multiple wind farms
an ultra-short-term prediction model of wind power based on multi-location NWP and gated recurrent unit (GRU) is proposed. First
the importance of multi-location NWP information on power generation in wind farms is analyzed through random forest method. The cumulative contribution rate is used to extract the effective information in NWP
and the weighted NWP information and historical power data are used as the input variables in the prediction model. Then
the improved gray wolf optimization algorithm is selected to optimize the parameters of the GRU
and a multi-variate time series prediction model is established for ultra-short-term prediction of power generation in wind farms. Finally
the measured data of a wind farm in China is selected for example analysis
and the effectiveness and feasibility of the proposed method are verified.
