With the development of smart grid technology, FACTS devices, such as SVC and STATCOM, are widely applied in practice. Since the FACTS devices possess fast dynamic response characteristics, they can provide effective support to power systems stability even during the transient process after severe contingencies. It is helpful to take into account the transient process stability constraints into reactive...
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,...
The volatility of load time series is noteworthy in load forecating analysis. Considering the characteristic of time-varying variance, a feasible method of short term load forecasting based on Stochastic Volatility (SV) models is presented. The Quasi Maximum Likelihood Estimate (QMLE) is brought in to specify the standard SV model. The model is transformed into state space form, and the Kalman filter...
