【 摘 要 】
This paper suggests a support vector regression model to make short-term load forecasting in Thailand by different training inputs. The primary objective of this paper is to describe the importance of data pre-processing and the external factors for accurate forecasting. The Electricity Generating Authority of Thailand (EGAT) provides the half-hourly electricity load demand. For numerical analysis, a dataset of net peak load of Thailand for a period of weeks from January 2016 to December 2017 is selected. The historical load demand is filtered for each day by Local regression filtering technique. After filtering the data, the effectiveness of input variables is important for accurate performance. Mean absolute percentage error (MAPE) is used to evaluate the model performance. By comparing the three models, model which considerate the temperature and seasonal factors enhances the model performance.
