Short-term irradiance prediction method based on image processing and multimodal data fusion, device thereof and storage medium

Abstract

Disclosed are a short-term irradiance prediction method based on image processing and multimodal data fusion, a device thereof and a storage medium in the field of solar irradiance prediction. The method includes the following steps: acquiring irradiance data, and carrying out blurring processing on the irradiance data, where the irradiance data which has been subjected to blurring processing includes time information and irradiance information; converting the time information into an image layer containing the position of the sun, and drawing a circular area with the solar imaging center coordinate as the center and the radius r to obtain a time information layer image; fusing a normally exposed all-sky image, an underexposed all-sky image and a time information layer image, inputting the fused image data into a pre-built short-term solar irradiance prediction model, outputting a short-term irradiance prediction value.
