Typical meteorological year construction method, generating capacity prediction method and related devices

Abstract

The invention provides a typical meteorological year construction method, a generating capacity prediction method and related devices. The typical meteorological year construction method comprises the steps of: obtaining historical meteorological data and a plurality of candidate meteorological parameters; determining the weight value of each candidate meteorological parameter based on the historical meteorological data; according to the weight value of each candidate meteorological parameter, screening out candidate meteorological parameters meeting a preset influence degree rule, and taking the candidate meteorological parameters as target meteorological parameters. According to the method, the target meteorological parameters are determined according to the influence degrees of the candidate meteorological parameters, and compared with a mode of manually selecting a fixed number of meteorological parameters according to experience, the accuracy of determining the meteorological parameters can be improved. Therefore, the accuracy of a typical meteorological year constructed based on the parameter value of the target meteorological parameters in the historical meteorological data is improved, and the accuracy of generating capacity prediction operation is improved according to the meteorological data of the typical meteorological year, so that the accuracy of photovoltaic generating capacity prediction is also improved.
