“…The impact of wind farm on system stability has been concerned. References [6][7][8] analyzed the influence of DFIG on the low-frequency oscillation characteristics and damping characteristics of the system after grid-connected; Reference [9] analyzed the influence of CSWT on the transient stability of the system at different wind power penetration rate wind power penetrations; Reference [10] compared and analyzed the influence of different capacity DFIG at the same node and different nodes the ystem transient stability ; Reference [11] compared the effects of different wind turbines on transient stability and small signal stability of the system under the same wind power penetration; Reference [12] analyzed the changes of wind turbine rotor angle, bus voltage and reactive power after the grid connection of different types of wind turbines, but it did not involve the study of transient stability and low-frequency oscillation characteristics of the system. This paper focuses on the influence of CSWT and DFIG on the system transient stability when connected to systems with different magnetic permeability.…”

With the gradual integration of large wind farms, the wind power penetration in power system is gradually increasing. Since different wind turbines access grid may have different effects on the system, it is necessary to study the effect of different wind turbines access grid on the system transient stability. This paper makes a comparative study on the system stability of constant speed wind turbine (CSWT) and the doubly-fed induction generator (DFIG) after grid-connected. Firstly, we present the dynamic models of CSWT and DFIG. Then, we use IEEE 3-machine 9-bus system to study the effect of CSWT and DFIG connected to the system on the system transient stability under different wind power penetration. Simulation results show that with the increase of wind power penetration, the transient stability of the system shows a trend of increasing first and then decreasing. However, DFIG will deteriorate the system transient stability as wind power penetration increases.
