Electric quantity prediction method and device for intelligent optimization analysis of power utilization cost

The invention discloses an electric quantity prediction method and device for intelligent optimization analysis of power consumption cost. The method comprises the steps: carrying out the data cleaning of collected user data, and obtaining the cleaned user data; carrying out modeling sample screening processing on the cleaned user data to obtain screened user data; performing clustering processing on the screened user data by taking preset classification types as clustering centers to obtain clustered user data; performing feature construction processing based on the clustered user data to obtain user data features; performing prediction model selection in a preset prediction model based on the number of users in the user data and the user data characteristics, and obtaining a selection prediction model; and inputting the user data features into the selection prediction model for power consumption prediction processing to obtain a power consumption prediction result.
