| 摘 要： | 给出一种求解组合优化问题的全局搜索算法——有记忆的模拟退火算法解决放射性配电网中电容器的优化配置问题。该算法获得全局最优解的几率大大高于单纯的模拟退火算法，且计算时间上几乎没有增加。通过一种较为精确的计算方法——阻抗矩阵法求解网损微增率，从而确定无功补偿的最优点。潮流计算采用前推回代法。应用于IEEE69和IEEE33母线系统获得了满意的结果。

| Abstract: | A global solution algorithm for combinato rial optimization problem based on simulated an nealing with memory is presented,which is used in the optimal capacitor placement of radial distribution systems.Its probability of obtainin g the global optimization is much higher than that of simple simulated annealing,nearly without any time increment.The network sensitivity is calculated with a more precise method,impedance matrix method,to determine the optimal locations for reac-tive compensation.Back/forward sweeps are selected for power flow calculation.This method has been tested in IEEE69bus system and IEEE33bus system with satisfying results. |

| Keywords: | simulated annealing with memory network sensitivity reactive compensation back/forward sweeps |
