基于电力系统暂态稳定分析的暂态能量函数法，提出了一种有效的方法，用于给定初始运行条件和指定事故时的发电机和临界线路潮流的稳定约束重新调度。在暂态稳定约束中使用能量裕度对发电量变化的敏感性，并使用分布因子来监测和约束临界线路流量。该问题被制定为一个多目标优化问题，这是解决使用的目标规划算法，包括一个明确的知识库。该方法已成功地测试了两个电力系统：17台发电机和50台发电机的测试网络。>
An effective approach, based on the transient energy function (TEF) method of power system transient stability analysis, is proposed for stability-constrained rescheduling of the generation and critical line flows for a given initial operating condition and designated contingency. The sensitivities of the energy margin with respect to changes in generation are used in the transient stability constraints, and distribution factors are used to monitor and constrain the critical line flows. The problem is formulated as a multiobjective optimization problem, which is solved using a goal programming algorithm that incorporates an explicit knowledge base. The approach has been successfully tested on two power systems: a 17-generator and a 50-generator test network. >
