Large-scale wind power interconnection is putting forward higher requirements on power system numerical simulation. The consistency of dynamic behavior simulation of power systems with large-scale wind power has important influence on operation

control and stability decision. An evaluation index system of simulation consistency is developed. A simulation consistency evaluation method based on Monte Carlo simulation is proposed

and the doubly-fed induction generator(DFIG)wind generator models of PSASP and PSS/E are compared. A numerical example is given to evaluate the electromechanical transient simulations of two kinds of software at different wind power penetration rates. The results show that with an increase in wind power penetration

the simulation consistency of the two kinds of software is getting worse.
