The invention relates to a power prediction method based on a wind-solar hybrid model. According to the prior art, wind power and photovoltaic power are predicted separately, however, according to the power prediction method based on the wind-solar hybrid model, only one BP neural network prediction model is adopted to achieve prediction of the output power of a wind power plant and the output power of a photovoltaic power station of a whole area at the same time, prediction accuracy is improved while the prediction method is simplified, and therefore the method has higher engineering application value.
