Abstract:
Background: As a renewable energy, solar energy has the advantages of being nonpolluting,
clean, and renewable. With the variability of solar radiation, the complexity of meteorological
factors, and other uncertain changes, how to measure its comprehensive uncertainty is very important.
Objective: The inherent regularity of the uncertainty behavior of photovoltaic power generation is revealed
by the change process of photovoltaic power generation.
Methods: Using the empirical wavelet transform (EWT), the uncertainty measurement was studied
from the perspective of social physics, and an optimized intelligent prediction model (PSOBOALSTM)
was proposed based on the uncertainty.
Results: The intelligent prediction model (PSOBOA-LSTM) has a better prediction effect and higher
accuracy than other models, and reveals the internal mechanism of the photovoltaic power generation
system from the perspective of physics and sociology.
Conclusion: Using the PSOBOA-LSTM model can better facilitate the power dispatching department
to reasonably arrange conventional power generation, coordinate operations and make maintenance
arrangements based on the predicted photovoltaic power generation, and solve problems arising from
the connection between grid dispatching and photovoltaic power generation forecasting.
