摘要：

A new generation rescheduling model is proposed for transient stability enhancement of power systems, which can optimally reallocate power generations for eliminating potential transient stability threat. The idea of angle norm has been introduced to develop a sensitivity-based transient stability constraints of the rescheduling model. Trajectory sensitivity mapping technique is studied to evaluate the sensitivity factor of the angle norm at maximum swing angle to the power input of generators. The augmented Lagrangian method is employed to solve the rescheduling problem in an iteration manner. Case studies on the IEEE 50-generator test power system are reported to verify the effectiveness of the proposed generation rescheduling method.
