Abstract: With the continuous development of photovoltaic power generation industry, the accuracy of photovoltaic power prediction is crucial for the safety of the power grid, in order to further improve the accuracy of photovoltaic power prediction, this paper proposes a short-term prediction method of photovoltaic power based on LSTM-EAA-Transformer model. By analyzing and comparing the proposed method with several commonly used time series prediction models, it is proved that the proposed prediction method has higher accuracy and better robustness for the short-term prediction of PV power.
