Zusammenfassung:The invention provides a solar eclipse event-oriented photovoltaic station output prediction method and system, and relates to the technical field of photovoltaic output prediction, and the specific scheme comprises the steps: constructing an intraday solar radiation intensity model, and correcting the intraday solar radiation intensity model through the sun shielding rate; based on the corrected intraday solar radiation intensity model, constructing an output model of the photovoltaic station to be predicted; the influence of the temperature of the photovoltaic module on the photoelectric conversion efficiency is considered, the temperature correction coefficient of the efficiency of the photovoltaic module is calculated, and the photovoltaic station output model is corrected; utilizing the corrected output model to predict the output dynamic change condition of the photovoltaic station during the solar eclipse transit period; according to the method, factors such as solar radiation intensity in the day, the
