China's Meteorological Administration has released an AI solar radiation forecasting model called Fengyuan Radiation Perception and Forecasting Model, according to a Xinhua report relayed by 36Kr. The report describes it as the country's first end-to-end AI solar radiation forecasting model driven by a fusion of geostationary satellite data and a ground-based minute-level radiation observation network, and says it enables real-time monitoring and ultra-short-term forecasting of ground solar radiation stations and grids nationwide. It is positioned as technical support for ultra-short-term photovoltaic power forecasting.
