基于协同聚类与优化分解的时序卷积双向神经网络短期光伏功率预测方法
Short-Term Photovoltaic Power Forecasting Based on Collaborative Clustering and Optimized Decomposition for Temporal Convolutional Bidirectional Neural Networks
摘要
Abstract
To address the issue of low prediction accuracy in photovoltaic power generation caused by the intermittency and volatility resulting from weather changes,this paper proposes a multi-level short-term photovoltaic power forecasting method.The method is based on collaborative clustering using self-organizing map and K-means algorithm(S-Kmeans),and an improved artificial lemming algorithm(IALA)-optimized variational mode decomposition(VMD),combined with a temporal convolutional network(TCN)and bidirectional gated recurrent unit(BiGRU).First,key meteorological factors are selected through correlation analysis,and photovoltaic data is classified into three typical weather conditions-sunny,cloudy,and rainy by using the S-Kmeans co-clustering method.Then,the IALA is employed to adaptively optimize the VMD parameters,enabling optimal decomposition of the photovoltaic power series and capturing local signal features more effectively.Finally,a TCN-BiGRU model is constructed for each subsequence,and the prediction result is obtained through component forecasting and global reconstruction,thereby improving prediction accuracy.Experimental results show that the proposed model outperforms the comparison models across all performance metrics under various weather conditions,validating its effectiveness in short-term photovoltaic power forecasting.关键词
