摘　　要：考虑到无功电压分区控制对区域无功平衡能力的要求,提出了区域负荷无功裕度的概念,并建立了同时考虑节点间电气耦合程度、区域静态无功平衡能力与无功储备分区要求的无功电压优化分区模型。模型包括使各分区区域电气半径平方和最小与使所有分区中区域负荷无功裕度值最小的分区无功裕度值最大两个目标函数,约束方面要求各分区内静态无功平衡。针对所建模型的特点采用了多目标自适应进化规划算法求解,并基于IEEE 39节点算例系统,仿真对比分析了所提方法的特点,仿真结果验证了方法的有效性。In view of the requirement of network partitioning for reactive power and voltage control on regional reactive power balance, a concept of regional reactive power margin is proposed. An optimal network partitioning model is developed for reactive power and voltage control considering electrical coupling degree between buses, static reactive power balance ability, and partition requirement of reactive power reserve. This model includes two objective functions, i.e., minimizing the sum of squares of all areas＇ electrical radii and maximizing the regional reactive power margin in the area with minimum reactive power margin. The constraint on the model is static reactive power balance in all areas. For the characteristics of the model developed, the multi-objective adaptive evolutionary programming algorithm is used for solution. Finally, simulation results on an IEEE 39-bus system and comparisons with other network partitioning methods show that the method proposed is effective.
