风力发电机组是微电网的重要发电单元,风速的随机变化对微电网潮流具有重要影响.建立了异步发电机数学模型,论证了接入线路阻抗与接入点电压变化量之间的关系,并分三种情况对电压稳定性进行分析.研究含风力发电的微电网概率潮流算法,通过对BenchMark低压微网的仿真,分析在风速随机变化情况下微电网潮流的概率特征,所提方法能够为电网调度人员优化分布式能源及负荷配置提供一定的参考.“,”The wind turbine is an important unit of the microgrid and the random variation of wind speed will put an important influence on the microgrid power flow. The mathematics model of asynchronous wind turbine (AWT) is set up to analyze the relationship of access line impedance and the voltage variation at AWT access point. Voltage Stability of the microgrid is analyzed in three different situations. The variation and probability distribution characteristics of the microgrid power flow are studied according to the simulation of low voltage BenchMark microgrid. The proposed method could help dispatch personnel to optimize the configuration of distributed energies and loads.
