This application belongs to the interdisciplinary field of
new energy power generation and meteorological forecasting, specifically relating to an intelligent prediction method and
system for photovoltaic
snow accumulation loss. The method includes: real-time acquisition and fusion of multi-
source data from satellites, ground stations, and the power
plant itself to form a spatiotemporally aligned
feature dataset; calculation of key physical features such as the equivalent optical thickness of the
snow layer and power attenuation rate based on this dataset, and inputting these features into a pre-trained identification module to dynamically determine the current
snow accumulation stage; inputting time-
series data containing physical features into the
encoder of a pre-trained
physics-AI
hybrid prediction model to extract a high-dimensional
latent vector representing the current comprehensive state; and intelligently selecting the corresponding dedicated prediction sub-module based on the identified snow accumulation stage
label to generate an accurate prediction sequence of photovoltaic
power output loss rate for future periods based on the
latent vector. This method achieves multi-source
information fusion, physical mechanism embedding, and process adaptive prediction.
