Using Seasonal Time Series Models to Forecast Electrical Power Consumption in Fallujah City


This research deal with using seasonal time series models to study and analysis the monthly data on consumption of electricity in Fallujha city for the period (2005-2010) , whereas this models are distinct with high accuracy and flexible in analysis time series . The results of application show that the proper and efficiency model for representing time series data are the multiplicative seasonal model of order : SARIMA(1 , 1 , 1)×(0 , 1 , 1)12 According to estimation results of this model done forecasting to monthly consumption of electrics capacity for two years ahead from the period Jan. 2011 to Dec. 2012 , these values show a harmonic direction with the same original time series.
