Photovoltaic output power prediction method and system, medium and electronic equipment

The invention provides a photovoltaic output power prediction method and system, a medium and electronic equipment. The photovoltaic output power prediction method comprises the following steps: acquiring meteorological data of a to-be-predicted area; and obtaining a photovoltaic output power prediction result of the to-be-predicted region according to the obtained meteorological data and a pre-trained long-short-term memory network. According to the method, the Bayesian optimizer is used for optimizing the weight and the threshold value of the long-short-term memory network, the defect that traditional long-short-term memory network training is prone to falling into local extreme points is overcome, and the photovoltaic prediction precision and efficiency are effectively improved; and then, on the basis of a deterministic prediction result, photovoltaic power probability prediction intervals under different confidence conditions are calculated, so that the prediction precision of the long and short-term memo
