摘　　要：对于电力系统无功分级控制的分区划分问题,提出了一种针对确定分区数量的无功控制分区方案最优化方法,使用加权电气距离表征无功源、受控点及控制分区间的耦合度,使分区方案更为均衡,并在降低分区之间耦合度的同时增强分区内部耦合度。所提方法首先将受控点分配至各个无功源,进而构建线性整数规划模型,最后使用成熟算法进行求得最优解。对IEEE39节点标准测试系统的仿真结果验证了方法的有效性,对实际电力系统的仿真验证了方法的实用性。Aiming at the problem of partition division for reactive power hierarchical control of the power system, this paper presents an optimal method for reactive power control partitions countering given partition numbers. This method uses weighted electrical distance to represent coupling factor of reactive power sources, controlled points and control partitions so as to keep the partition scheme in balance and increase internal coupling degree of partitions at the same time of reducing coupling factor among partitions. The proposed method firstly allocates controlled points to every reactive power sources, and then constructs a linear integer programming model, finally uses mature algorithms to solve the optimal solution. Simu- lation of IEEE 39-bus test system verifies validity of this method and simulation on actual power systems verifies practicabili- ty of the method.
