LI Jiayi, ZHANG Shengyan, HE Jie. Photovoltaic power prediction based on a combined CNN-XGBoost model[J]. Ningxia Electric Power, 2024, (3).DOI: 10.3969/j.issn.1672-3643.2024.03.002.
To enhance the accuracy of photovoltaic power forecasts
this study begins with data preprocessing
which involves missing values and normalization.Pearson correlation coefficient is then used to analyze meteorological factors that best correlate with photovoltaic power
thereby reducing the model's input dimensions and complexity.Finally
a combined predictive model is tested using a convolutional neural network and extreme gradient boosting(CNN-XGBoost)model.The test results show that the proposed model successfully enhances the accuracy of photovoltaic power forecasts by significantly reducing the root-mean-square error in predictions.
