摘　　要：以运行时网络损耗最小为目标建立含DG配网重构的模型,采用考虑种群约束的编码规则改进遗传算法,简化了环网判断过程,提高了求解效率,有效实现了全局最优搜索,并防止了过早收敛.A model of distribution network reconfiguration considering DG is established,in which the object function is minimum network loss.Coding rules considing the population constraints are adopted to improve genetic algorithm to solve the model,simplifying the process of loop judgment,so it can improve the solution efficiency.Implement global optimal search effectively,and with hybrid crossover and mutation operation,it can prevent premature convergence effectively better than the traditional methods.
