摘　　要：随着配电网复杂程度增加,动态电压恢复器(DVR)优化配置求解难度进一步增大。为提高计算效率,本文设计了一种基于二进制编码和实数编码的混合编码多种群遗传算法,并应用于求解DVR优化配置问题。首先,以二进制编码表示安装位置,实数编码表示DVR输出补偿电压对可行解进行编码;然后,以治理方案总投资成本最小为目标函数,DVR安装容量及用户电压要求为约束条件,建立基于DVR单位容量成本函数的DVR配置模型;接着,将所提混合编码方法应用于多种群遗传算法求解DVR优化配置;最后,通过求解IEEE 33节点配网算例,获得了优化配置结果,验证了所提混合编码方法能有效提高计算效率和求解精度。With increase of complexity of distribution network,the optimization configuration solution of dynamic voltage restorer(DVR)becomes more difficult. For improving calculation efficiency,a kind of multiple population genetic algorithm(MPGA)based on binary encoding and real encoding is designed in this paper and is used to solve the optimization of the DVR. First,the binary encoding refers to the installation location and real encoding refers to the output compensation voltage of DVR to encode the feasible solution.Then,the minimum total investment cost of the control scheme is taken as the objective function and the DVR installation capacity as well as the user’s voltage requirement as the constraint condition,the DVR configuration model based on DVR cost per unit capacity function is set up. After that,the proposed hybrid encoding method is applied in multiple population genetic algorithm(MPGA)to solve DVR optimization configuration. Finally,the optimization result is obtained by solve example of distribution network of IEEE 33 node. It is verified that the proposed hybrid encoding method can improve effectively calculation efficiency and solution accuracy.
