| Abstract | The Box-Jenkins technique of time series analysis was employed to model the wind regimes at three stations in Malaysia. Wind velocity was split into two independent orthogonal components for the purposes of data transformation and modeling. Simulation was carried out for these two component series. The two simulated series were then combined to obtain the wind speed and direction. The seasonal autoregressive-moving average model, viz., the ARIMA (1,0,1) x (0,1,1)24 model, was found to be the most suitable. Simulation using this model was performed, together with two other closely-related models. Comparison of the simulation results justified the choice of the model. It was found that the combined techniques of differencing, harmonic analysis and standardization could not entirely remove the strong daily cyclicity exhibited by the data. Nevertheless, the identified model performed satisfactorily in terms of the absolute error in the mean and standard deviation. |
