In order to consider the influence of multiple factors on electricity and improve the accuracy of monthly electricity forecasting. A monthly electricity forecasting method is proposed based on the K-L information method and ARIMA error correction. Based on screening relevant indicators
the correlation analysis method is used to make regression modeling on the influence indicators and electricity
calculate of fitting errors
and construct a new non - stationary time series
combined with the ARIMA model to modify this series. Monthly electricity predictions obtained with better accuracy
