摘　　要：由于电力市场的竞争机制使电网运行在电压稳定裕度很低的工作点,因此电力系统的电压稳定问题变得日益突出。文章在分析电压稳定模型时考虑了负荷特性,建立了分析静态电压稳定的优化数学模型,提出了应用基于连续潮流算法的遗传算法求解系统的最大静态稳定裕度。对IEEE 14节点标准网络的计算结果证明了模型的正确性以及算法的有效性。Due to the market principle of open access, power systems often operate at the working point with low voltage stability margin, so the voltage stability of power system becomes more and more important. Here, in the establishment of the model to analyze the power system voltage stability the load features are considered, then an optimal mathematical model for voltage stability analysis is constructed and an algorithm in which the continuous power flow (CPF) based genetic algorithm is applied to solve the maximum static stability margin. Using this algorithm to IEEE 14-bus standard network, the calculation results indicate that the constructed model is correct and the proposed algorithm is effective.
