| 摘 要： | 采用细菌群体趋药性算法求解电力系统无功优化问题.针对n维变量寻优问题,提出将n维空间的求解问题化简为(n-1)个二维空间求解,并给出了新的求解此二维空间的表达式;针对细菌个体与群体的搜索特点,引入自适应步长,对细菌每次移动过程中的移动步长和方向进行自适应调整;针对细菌迭代过程中寻找到的最优值,引入最优状态板,使最优值不被随机抛弃.这些策略提高了算法运算速度,同时保证算法全局搜索的能力.对IEEE30节点测试,证实该法在无功优化计算中的有效性.

| Abstract: | The BCC algorithm is employed to solve the problems of reactive power optimization.The optimization of n-dimensional problem was simplified as the optimization of n -1 sub-problems of 2-dimension by presenting the new formulation.As for the searching characteristic of a cell and colony,the author introduces self-adaptive step strategy,which automatically adjusts the step length and the direction of bacterium.The bullitn can remain the best direction of bacter which may be abandened at randen.These strategie... |
