Research on stable operation of grid-connected wind farms

The current research on the steady-state operation of grid-connected wind farms is introduced,including the power flow calculation models for power systems which contain wind farms,the analytic methods and models for the static voltage stability of wind farms,the voltage static stability indices and measures to control the voltage stability,the factors influencing the maximum power injection of wind farms and main relevant analytic methods,indices for wind farm scale,and the capacity credit.The above issues are analyzed theoretically,and the methods and measures are classified and assessed.
