A Singular Spectrum Analysis Technique to Electricity Consumption Forecasting

Abstract

Singular Spectrum Analysis (SSA) is a relatively new and powerful nonparametric tool for analyzing and forecasting economic data. SSA is capable of decomposing the main time series into independent components like trends, oscillatory manner and noise. This paper focuses on employing the performance of SSA approach to the monthly electricity consumption of the Middle Province in Gaza Strip\Palestine. The forecasting results are compared with the results of exponential smoothing state space (ETS) and ARIMA models. The three techniques do similarly well in forecasting process. However, SSA outperforms the ETS and ARIMA techniques according to forecasting error accuracy measures.
