面向新能源基地的频率动态响应模型研究
Research on Frequency Dynamic Response Model for New Energy Bases
摘要
Abstract
In order to improve the cognition and analysis level of frequency response characteristics of new energy power system with high penetration rate,the small signal analysis method is applied to the component equivalence of doubly-fed asynchronous wind turbine models at different wind speed stages to obtain the two-input,single-output wind turbine equivalence model.On this basis,an improved frequency response model that can take into account the FM characteristics of a variety of wind speed is proposed,and the model is combined with a typical system frequency response model to establish a frequency response model that considers different wind conditions and wind turbine generator system(WTGS)with different FM characteristics.In this paper,the model is used to simulate and analyze the improved IEEE 118-node system,and the results show that the model can accurately and effectively analyze the frequency response characteristics of the high penetration wind power grid-connected system.关键词
