Time series analysis and its application of electrical energy quantity generated by using wind turbines

In this study, it is aimed to make an estimation about the amount of energy to be obtained from 9 wind turbines with equal characteristics installed in Atik Belen Plateau in Eastern Mediterranean Region by using time series for later periods. In addition, the amount of energy depends on wind speed, air temperature and active operating hours of the turbine obtained from wind turbines was investigated with the help of multiple linear regression analysis and the parameters depending on the energy production were examined. The analyzes were performed with IBM SPSS 20 and Eviews10 package programs. In the study, it was found that the energy produced by wind turbines was not stable but it was found to be stagnant according to the Ljung- Box Test of past values. In addition, it was found that the variables in the research were stable at level values according to the ADF unit root test and that the first differences were stable according to the P-P unit root test test. In the study, according to the output of forecasting model selected as a result of Ljung-Box Test, it is seen that the energy production forecasts for the months of 2020 are stable compared to the previous months. In addition, it was determined that weather temperature had no direct significant effect on the amount of energy generated by the turbines, whereas wind speed and operating time of the turbines had direct significant effects.
