Abstract	This paper carried out the available transfer capability(ATC) calculation based on transient stability constrained optimal flow(TSCOPF). The model of ATC calculation the improved differential evolution algorithm (IDE) was established. This model adopted the hybrid method to judge the transient stability of the system, which solved imprecision problem in confirming boundaries of the rotor angle relative the center of inertia when the power-angle restriction was made as the stability criterion. The new variations and cross strategies were presented in the differential evolution process. The better global search capability the faster rapidity of convergence and search accuracy were assured through the introduction of the constant idea of simulation anneal tactics and time-variation cross probability. Focus on the characteristics of differential evolution algorithm (DE), the constraints of model adopted synthesis sufficiency function method to dispose based on state variable practicability according to fixed proportion to test infeasible solutions, which avoided the difficulties in defining the penalty divisor in normal penalty function method and increased the accuracy of the target value. The simulation results indicate that the improved strategy of DE algorithm is simple and effective, and the improved DE algorithm used to calculate ATC based on TSCOPF is faster and higher accuracy.
