摘要

本文介绍了一种利用基于前向/后向扫描算法的不平衡径向配电系统自动调压器建模方法。首先在除源母线外的每个支路上找到功率损耗指标,并选择功率损耗指标最高的母线作为稳压器的最佳放置位置。通过最小化由功率损耗组成的目标函数,获得将电压保持在不平衡径向配电系统极限内的稳压器的分接位置。采用粒子群算法求解稳压器分接位置的选择。通过算法对稳压器进行初始选择、安装和分接位置的设置,以提供良好的电压分布,使配电网的功率损耗最小。在25个母线不平衡径向配电系统的测试系统上验证了该方法的有效性。

Optimal location of voltage regulators in unbalanced radial distribution system for loss minimization using particle swarm optimization
This paper describes an approach for modelling of automatic voltage regulator using the forward/backward sweep-based algorithms for unbalanced radial distribution systems. Power loss indices are first found at each branch except source bus and the bus that has the highest power loss index are picked as the best location for the voltage regulators placement. To obtain the tap position of the voltage regulators that maintain the voltages within the limits of the unbalanced radial distribution systems by minimizing an objective function, consisting of power loss. PSO is used to find the selection of tap position of the voltage regulators. An algorithm makes the initial selection, installation and tap position setting of the voltage regulators to provide a good voltage profile and to minimize power loss along the distribution network. The effectiveness of the proposed method is illustrated on a test system of 25 bus unbalanced radial distribution systems.
