摘要
连续潮流法能较好克服潮流方程在极限点附近的病态,是求取静态电压稳定裕度的常用方法。在连续潮流法的基础上,结合经过改进的差异进化算法,通过对变量的组合优化,求取系统静态电压稳定安全裕度。对KK11节点系统的计算结果表明了对进化算法所作改进的有效性。
The continuous power flow method can readily overcome the abnormality of the power flow equation in neighborhood of limits and is frequently used for determining the static voltage stability margins. By combining the continuous power flow method with improved differential evolution calculation, the static voltage stability margin is found via optimal grouping of relevant variables. Calculation results of a KK 11 bus system shows the effectiveness of the proposed calculation improvement. Figs 4, table 1 and refs 11 .
