In response to the small disturbance stability problem in the power system caused by the uncertainty of high penetration wind power output,a probability analysis method was adopted,combined with system characteristic roots,damping ratio,distribution factors and related indexes,a probability small disturbance stability evaluation index system under multiple operating modes was established.The simulation results of the IEEE 8-machine 24 node example show that the quantified indexes can effectively provide reference for the adjustment of generator output and related control positioning,and provide theoretical basis for further stable operation decisions.
