In response to the current scarcity of historical operating data for some wind farms in China
this paper proposes a data-driven wind farm power generation migration prediction model based on a convolutional neural network gated-recurrent unit(CNN-GRU) model. Firstly
based on the advantages of CNN and GRU models
a CNN-GRU combined model is constructed to eliminate overfitting problems and reduce training cycles. Secondly
the -means clustering algorithm is used to cluster the historical operation data of wind farms
reflecting the features of large-scale scenes with a few typical scenes
reducing computational complexity while improving training accuracy. Thirdly
the migration conditions in each migration prediction scenario are further clarified
which not only avoids overfitting problems during the migration process
but also provides decision-making for parameter migration between the source domain and the target domain. Finally
compare the performance of the different migration prediction models is and compared the best migration prediction method is selected. Based on the training results
it can be concluded that the transfer prediction accuracy of the modified CNN-GRU model is significantly higher than that of the traditional LSTM model and the uncorrected CNN-GRU model. The -means clustering algorithm can be used to optimize and identify reference wind farms
and to further improve the accuracy of transfer prediction results of the CNN-GRU combined model.
