The present invention relates to the field of
solar energy technology, and discloses a prediction method, device,
computer equipment and storage medium for solar
radiation distribution. The prediction method for solar
radiation distribution includes: obtaining the circumsolar
radiation intensity and normal radiation; obtaining the circumsolar radiation ratio according to the circumsolar radiation intensity and normal radiation; obtaining a full
sky image, performing
feature matching between the full
sky image and a preset cloud feature, and generating cloud amount, cloud shape and cloud bottom height according to the
feature matching result; obtaining a first
direct radiation value of the solar disk; measuring a second
direct radiation value of the solar circumference; measuring a scattered radiation value of the solar periphery; predicting the solar radiation distribution according to the circumsolar radiation ratio, cloud amount, cloud shape, cloud bottom height, the first
direct radiation value of the solar disk, the second direct radiation value of the solar circumference and the scattered radiation value of the solar periphery. The present invention predicts the solar radiation distribution according to direct radiation and scattered radiation at different angles, and the prediction result obtained is more accurate.
