Study and Forecast of Electricity Costs of Residential Buidings By using smooth, exponential method

Abstract

The study and prediction of the electrical energy consumption of residential buildings using the conventional smoothing method has two purposes: to study the electrical energy consumption of the building. And to compare the RMSE values of the predicted power consumption of each building. Electricity prices are reported from January 2014 to December 2015 for a 24-month period. In June

2014, the maximum electricity cost was Bt. 26,598.10. As of February 2015, the lowest electricity cost

was 10,631.79 Baht, equivalent to 2,165 kWh, while the EViews 8 program was used as a support. In the projection All four RMSE method are Single Exponential Smoothing with RMSE of 3289.076 Double Exponential Smoothing RMSE of 3645,200. Holt-winters-Additive RMSE was 882.2855 and Holt-Winters- Multiplicative RMSE was 930.0315 and the least significant one was Root Mean Squared Error (RMSE). The lowest RMSE was Holt-winters-Additive with Root Mean Square Error of 882.2855.
