Embodiment Construction
[0068] The present invention will be further described below in conjunction with accompanying drawing.
[0069] see figure 1 , the ultra-short-term prediction method of the photovoltaic power plant irradiance of the present invention, comprises the following steps:
[0070] Step S1, extract the actual irradiance data of the place where the photovoltaic power station is located in a given period of time from the historical database, and perform anomaly inspection on the extracted actual irradiance data according to the theoretical extraterrestrial irradiance in the same time and area, and check the abnormality The irradiance data after inspection is normalized; in this embodiment, the meteorological observation station of the photovoltaic power station is used to collect the irradiance data on the spot, and the collection frequency is 30 seconds, and then the average value of the irradiance for 15 minutes is calculated. value, stored in the historical database; Step S1 specifi...
