Abstract:
With the increasing electricity demand in Thailand to support the growing industrial, commercial and residential sectors, electricity demand forecast is crucial for electricity suppliers to manage the demand-supply chain to reduce the electricity cost as much as possible. The management is also known as Demand Side Management (DSM). We present techniques for demand side forecasting using Support Vector Machine-Regression (SVM-R) by analyzing one-minute intervals of electricity data collected from a sample group of industrials, commercials and residences. In spite of long-term forecast, we propose the SVM-R model that forecasts a short-term load based on a previous week or month. In addition, the model was tuned to optimize parameters based on real-life dataset collected from our research project. In the model, we consider variables including the time-of-day and the type-of-day such as workday, weekend or holiday.
