摘    要:用交流概率潮流方法对含有风电场的电力系统进行了分析。采用结合累积量和Gram-Charlier级数的方法,将直流概率模型拓展为交流概率模型,采用3参数的weibull分布来描述风速的随机变化,同时将异步风机处理为PQ节点,建立了风力发电机组的概率模型,基于风电模型对IEEE-30节点系统进行计算,得到了各节点电压的概率分布和各支路潮流的概率分布,分析比较了风电场加入前后电力系统的节点电压和支路潮流变化情况。

关 键 词:概率潮流  风电场  累积量  Gram-Charlier级数

Abstract:The power grid containing wind farms is analyzed by AC probabilistic load flow.By use of the approach integrating cumulants and Gram-Charlier series,the DC probabilistic model,is extended into AC probabilistic model,in which a three-parameter weibull distribution is adopted to describe the random variation of wind speed,meanwhile the asynchronous wind turbine generator is treated as PQ node,then a probabilistic model of wind turbine generator is built.Based on the built model the calculation of IEEE 30-bus ...
Keywords:probabilistic load flow  wind farms  cumulant  Gram-Charlier series
