A Proposed Model for Electricity Demand Forecasting in Ecuador Considering Akaike Criterion

Abstract:

The objective of electrical load forecasting is to satisfactorily and accurately pbkp_redict the electrical demand that could increase or decrease in the future. A large number of engineering applications have accurate and reliable electricity demand forecasting models. Accurate load forecasting helps to plan the capacity and operation of different utilities to reliably supply power to consumers. The present work establishes the collection of annual and monthly historical data, obtained from the Ecuadorian electricity regulation and control agency. This study is focused on the comparison of the SARIMA regression model that considers the seasonality of electrical demand data, providing an evaluation of the model based on the Akaike information criterion. The input data have been divided into two data sets, one annual and one monthly, to build the forecasting model. By simulating the actual data, removing the last 5 years of data in the annual case and 2 years in the monthly case, the simulation results are checked against the actual data. The accuracy of the pbkp_rediction models has been evaluated using different error matrices. R software was used for the pbkp_rediction analysis having results with an error of less than 5% when comparing actual and estimated electrical demand.
