摘要

为了更好地采用串联补偿装置解决供电半径过大的配电网末端电压偏差问题和网络损耗问题

研究了确定串联补偿装置阻抗值和安装位置的多目标优化算法。以线路电压偏离度和网络有功损耗最小为目标函数建立了配电网串联补偿装置的参数多目标优化模型。运用NSGA-Ⅱ算法求解多目标优化模型

并获得帕累托解集

再采用逼近理想解排序法（TOPSIS）在解集中求得最优解。通过IEEE 34节点配电网算例验证了模型的可行性和算法的有效性。结果显示

本文所建立的模型与采用的方法可以快速有效地确定串联补偿装置的安装位置和容抗值

并优于单目标优化的结果。此外

在不同负载条件下串联补偿装置的最佳安装位置不同

可以采用多点串联补偿方法来获得更好的效果。

Abstract

In order to better solve the terminal voltage deviation problem and network loss problem of distribution network with large power supply radius

the multi-objective optimization algorithm for determining the impedance value and installation position of the series compensation device is studied.The multi-objective optimization model of the distribution network series compensation device is established based on the line voltage deviation and the minimum network power loss.The NSGA-Ⅱ algorithm is used to solve the multi-objective optimization model

and the Pareto solution set is obtained.Then the optimal solution is obtained in the solution set by TOPSIS（technique for order preference by similarity to an ideal solution）method.The feasibility of the model and the effectiveness of the algorithm are verified by an IEEE 34-node distribution network.The results show that the model and method adopted in this paper can quickly and effectively determine the installation position and capacitance value of the series compensation device.In addition

the optimal installation position of the series compensation device under different load conditions is different

and the multi-point series compensation method can be used to obtain better effects.
