摘　　要：系统安全运行和经济控制是电力运行中较难协调的问题。在最优潮流的基础上结合电压稳定分析,综合考虑安全运行和经济控制可获取合理的效果。该文综述了国内外研究人员对计及电压稳定的最优潮流的研究状况。首先阐述电压稳定指标和最优潮流等基本概念,研究了计及电压稳定的最优潮流建模问题,总结并提出了两种模型:约束型优化模型和多目标优化模型;其次介绍和分析了模型所采用的常见成熟算法及其应用策略,指出了各种算法的优点和缺陷;最后提出了该方面研究的几个需要深入解决的关键问题。Secure operation and economical controls, are significant problems of power system operation which are not coordinated well. Voltage stability analysis based on optimal power flow is considered to provide an appropriate scheme on voltage security and economical controls. In this paper, the academic research of OPF considering voltage stability is surveyed. Basic conceptions about voltage stability indices and optimal power flow are introduced firstly; the modeling of OPF considering voltage stability is summarized secondly, which includes constrained optimization model and multi--objective optimization modell and then the algorithms and strategies applied to the problem are commented, especially their advantage and weakness. Finally, several important aspects needing further research are presented.
