Embodiment Construction
[0073] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0074] Several mega-kilowatt-level photovoltaic power generation bases (or: photovoltaic power generation base groups) cover a large area, with harsh natural environments, and most of them are located in desert Gobi areas. For real-time optical resource monitoring of multiple million-kilowatt photovoltaic power generation bases, multiple photometering 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 prediction, it is necessary to adopt...
