The analysis on the characteristics of volatility can help to give a more precise description in load time series and may contribute to load forecasting performance. In this study, first, asymmetric effect in load time series is investigated, and the asymmetric ARCH type models, including EGARCH, TARCH, PARCH, and TCGARCH, are introduced as feasible methods for short-term load forecasting. Second,...
Wind speed forecasting is essential to wind power generation and operation. To improve the performance of wind speed forecasting, analyzing the characteristics of the wind speed time series is necessary, comprehensively, since wind speed change is irregular and may fluctuate violently. In this study, using the technique of the GARCH model kurtosis analysis, the leptokurtosis of wind speed is discussed,...
