随着电力系统的不断发展，基于化石燃料大规模利用的工业模式正在走向终结，而以新能源技术和信息技术的深入结合为特征的一种新的能源利用体系，即“能源互联网”即将出现。电力系统的稳定性问题也日趋重要，而暂态稳定控制又是稳定性研究的重中之重。有功出力的重新分配是暂态稳定控制的一种重要手段。轨迹灵敏度是系统参数对其运动轨迹影响程度的度量，揭示了系统的动态行为机制。研究基于轨迹灵敏度的有功出力重新分配的方法，结果显示该方法有助于提高系统的稳定性。

With the continuous development of power system, the industrial model based on the large-scale use of fossil fuels is come to an end, and with the deepening of new energy technology and information technology combined with the features of a new energy utilization system, namely “energy internet” will appear. The stability problem of the power system has received much attention, and the transient stability control is the key of the stability study. The generation rescheduling is an important means in transient stability control. Trajectory sensitivity is the measurement of the system parameters on its trajectory influence degree, and it reveals the mechanism of the dynamic behavior of the system. The generation rescheduling method based on trajectory sensitivity is studied;the results show that this method is helpful to improve the stability of the system.
