Electricity price prediction method and system containing market disturbance and meteorological change factors

The invention discloses a market disturbance and meteorological change factor-containing electricity price prediction method and system, and relates to the technical field of electrical engineering, and the method comprises the steps: calculating the deviation between a plurality of predicted load values and an actual load value of a continuous operation day in different time periods, and the deviation direction; obtaining transaction day whole province disclosure data published on the D-1 day, and performing difference correction on the latest whole province disclosure data; preprocessing training data and prediction data used for entering the electricity price prediction model; predicting day-ahead and intra-day electricity prices through a user-defined model by adopting a time sequence prediction method; and calculating the average change rate of the numerical weather forecast with the strongest timeliness before the transaction curve is reported and the numerical weather forecast when the power curve is r
