基于Tabu搜索的电压控制分区

电力系统的电压控制分区是一个非线性的大规模组合优化问题，使用常规方法常难以得到理想的结果。文中首先基于电压幅值对无功功率的灵敏度定义了电力系统各节点间的电气距离。然后根据电气节点间电气距离的关系，将电气节点映射到几何空间，从而将电力系统分区问题转化为几何空间中点的聚类问题，由此建立了电压控制分区的组合优化模型。Tabu搜索法被用于求解该模型。最后在IEEE 118节点测试系统上对该方法进行了验证，结果表明该方法有效、可行。

TABU SEARCH BASED NETWORK PARTITIONING FOR VOLTAGE CONTROL

The partitioning of electric power system for voltage control is a non- linear,large- scale com binatorial optimization problem.Conventional m ethods are not norm ally appropriate for such a problem.This paper first defines the electrical distance between the two nodes in power system based on the sensitivity of voltage to reactive power injection,then m aps the electrical buses into geometric space according to the defined electrical distance.Thus the problem of partitioning of power system is converted to that of the points clustering in geometric space. Based on this idea,a novel optim ization model for partitioning of power system for voltage control is established,and Tabu search m ethod is adopted to solve this model. Finally the feasibility and efficiency of the proposed m ethod are verified on the IEEE118- bus system.
