Embodiment Construction
[0098] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0099] The invention proposes a method and system for predicting ground irradiance through a sky image-irradiance model.
[0100] Please refer to the attached figure 1 , in the first embodiment of the method for predicting the surface irradiance through the sky image-irradiance model proposed by the present invention, the following steps are included:
[0101] Step S110: Establish a prediction model of surface irradiance, and use historical sky images to train the prediction model of surface irradiance.
[0102] Specifically, a BP (back propagation) neural network and a support vector machine (SVM) are used to train the above-mentioned surface irradiance prediction models respectively, so as to obtain two different surface irradiance prediction models.
[0103] Step S120: Obtain a plurality of current sky images sep...
