Embodiment Construction
[0032] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0033] This example is based on the measured data of 118 power stations in Badong County, Hubei Province from July 1, 2019 to February 29, 2020, including date, time, latitude, longitude and altitude of each power station, and the frequency of each inverter every 5 minutes. Power, irradiance per hour, ambient temperature, wind direction, wind speed, weather category, etc. The method of the present invention is described for the case of lack of irradiance caused by communication failure of photovoltaic power station equipment. The irradiance missing data interpolation method based on decision tree classification provided by the present invention, its process is as...
