摘要(Abstract)：

提出了一种大规模电网分层分区无功优化模型及其算法。根据电网解环运行及分层分区管理的特点,采用节点分裂法将电网进行分层分区解耦,即将220 k V与110 k V电网进行分层,110 k V电网分区管理。建立相应的分解协调模型,并通过分解协调内点法进行求解。该方法仅交换子网间少许的边界变量就可以将大系统完全等效解耦,使修正方程仅保留220 k V及以上电压等级主干网部分,从而使问题的求解趋于简便、快速。通过对8个测试算例的仿真分析,结果表明所提模型满足电网分层分区无功优化运行,具有较强的收敛性和快速性。

关键词(KeyWords)： 大规模电网;无功优化;分解协调;分层分区;原始-对偶内点法
