Comparison of Prediction Models
To further validate the superiority of the proposed model in photovoltaic power prediction, comparisons were made with Bi-LSTM, Bi-GRU, GRU, LSTM, and C-LSTM models. The overall performance comparison between the proposed model and other models is shown in Table 6. To illustrate the comparison of actual power values and power prediction results of different models under clear and cloudy weather conditions, Figure 10 (a) and (c) display continuous clear days from February 16, 2023, 0:00 to February 17, 2023, 24:00, while Figure 10 (b) and (d) compare cloudy days on January 20, 2023, 0:00–24:00 and February 5, 2023, 0:00–24:00.
