A Study of Wind Power Prediction Based on Data Cleaning and Personalized Federated Learning
In response to the volatility and quality issues of wind power data,a wind power prediction model based on data cleaning and series of gated recurrent unit(GRU)and attention mechanisms(Att)is proposed,and the parameters of regional model are transferred through federated learning.The Moreau envelope as a regularized loss function for federal learning is introduced,and the personalized federated learning with Moreau envelopes(PFedMe)is proposed.Taking into account the dual needs of data security and predictive performance,and providing a solution for new power plants to predict wind power.Finally,the dataset of Baidu dynamic space wind power prediction challenge is used for experimental verification.The results show that the proposed scheme achieves efficient model training and performance improvement while satisfying privacy and security constraints.
