摘要
提出相邻开关在染色体中相邻及构成同一环路的开关在同一基因块内的编码方法 ,交叉操作只进行对应基因块的交换 ,而将变异和逆转操作限制在基因块内的遗传操作策略克服了现有遗传算法 (GA)在配电网重构中应用时产生大量不可行解的不足 ,通过简化配电网结构 ,减少了 GA染色体的长度 ,从而进一步提高其计算效率。以网损的倒数作为适应度函数 ,比较简洁、有效 。
The paper presents an encoding m ethod of neighboring switches neighboring in the chrom osom e and switches in the same loop in the sam e gene.The crossover operation is done only on the corresponding genes.The m utation and inverse operation is limited within the gene.These strategies greatly reduce the infeasible solutions produced during gene algorithm operations in the application to distribution system reconfiguration.Further,a sim plifying distribution method is also proposed to reduce the length of chromosome and enhance the efficiency of the algorithm.The reciprocal value of the active power losses is taken to be the fitness function,which will be simple and effective.In particular,the results of several test com putations show that the proposed algorithm has higher searching capability.
