Abstract
This paper presents a fast identification and prediction method for the coefficient of steady frequency characteristics based on Grey system GGM(1,1) model. Based on analyzing and comparing the definition and formulation of steady frequency characteristics, identification method and Grey system theory, the constructing method of Grey model is proposed which is suitable for the prediction of power system steady frequency characteristics coefficient. By replacing the time data sequence with the equal measurement data sequence, the Grey system GGM(1,1) model is established with the maximum frequency deviation value under the same operation mode and increasing disturbance to predict and analyze the variation trend of coefficient of steady frequency characteristics. The calculation of K value for a certain operation manner of UHV power grid is done by using the model of GGM (1,1) of grey system. The calculation result is verified and its error within the simulation examples is also analyzed.关键词
