Embodiment Construction
[0072] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.
[0073] Several million kilowatt-level photovoltaic power generation bases (or called: photovoltaic power generation bases) cover a large area with harsh natural environment, and most of them are located in the desert Gobi area. For real-time optical resource monitoring of multiple million kilowatt-level photovoltaic power generation bases, multiple photometric stations should be established to form a photometric network to ensure full coverage monitoring of optical resources, thereby improving the accuracy of photovoltaic power generation power prediction. At the same time, in order to ensure the timeliness of photovoltaic power generation power prediction, it is necessary to use...
