摘　　要：考虑最恶劣情况下的网络最大传输能力,即至少输电容量,是电力市场环境下衡量输电系统电力传输能力的一个重要指标。在至少输电容量模型的基础上,考虑了电压稳定约束,提出了考虑电压稳定约束的至少输电容量双层优化决策模型,讨论了模型的性质,并给出了求解该模型的算法BiGA,该算法具有较好的鲁棒性。对IEEE 118节点系统进行了数据仿真,仿真结果表明了该模型及算法的合理性和有效性。Min-max transfer capability of transmission interfaces is an important parameter for the exchange of electric power among areas. To take the voltage stability into account when computing min-max transfer capabilities, a bi-level decisionmaking model based on a min-max transfer capacity formulation is proposed and the properties of the model are discussed. A more robust genetic algorithm named BiGA is also introduced to solve this model. The proposed notion of min-max transfer capacity provides more valuable information compared with traditional available transfer capability （ATC）. At last, the 118-bus IEEE RTS is utilized to evaluate the proposed model and the results demonstrate the reasonability and validity of the algorithm.
