Irradiance prediction method and system based on satellite remote sensing data

The invention provides an irradiance prediction method and system based on satellite remote sensing data, and the method comprises the steps: obtaining the satellite remote sensing data of a plurality of first photovoltaic power stations adjacent to a target photovoltaic power station at each moment, and carrying out the preprocessing of the satellite remote sensing data of the plurality of first photovoltaic power stations at each moment; determining a weather mode corresponding to each first photovoltaic power station at each moment and feature data corresponding to each first photovoltaic power station at each moment; determining irradiance prediction data of each first photovoltaic power station at each moment based on the weather mode corresponding to each moment and the feature data corresponding to each moment of each first photovoltaic power station; and determining the irradiance of the target photovoltaic power station at the to-be-predicted moment based on the irradiance prediction data of each fir
