Research on Multi-objective Active Reconfiguration of Distribution Network Based on Analytic Hierarchy Process and Genetic Algorithm

结合配电网的运行情况,提出了一种基于层次分析法和遗传算法的配电网多目标主动重构方法。首先,将开关操作次数引入目标函数,形成由降低网损、提高电压质量、减少开关操作次数三部分构成的目标函数。其次,引入层次分析法确定目标函数各部分的权重系数,通过确定目标层、准则层与方案层,构建层次结构模型,科学地确定目标函数各部分的权重系数。最后,利用遗传算法对IEEE 33节点系统进行重构,仿真结果验证了算法的有效性。

Combined with the operation of distribution network,a multi-objective active reconfiguration method of distribution network based on analytic hierarchy process and genetic algorithm is proposed.Firstly,the switching action times is introduced into the objective function,forming an objective function composed of three parts:reducing network loss,improving voltage quality,and reducing the switching action times.Secondly,the analytic hierarchy process is introduced to determine the weight coefficients of each part of the objective function.By determining the objective layer,the criterion layer and the scheme layer,the hierarchical structure model is constructed to scientifically determine the weight coefficients of each part of the objective function.Finally,the IEEE 33 nodes distribution network system is reconstructed by using genetic algorithm,and the simulation results verify the effectiveness of the algorithm.
