摘要(Abstract)：

智能软开关(soft open point,SOP)对配电系统运行经济性、灵活性和可靠性的提升具有重要作用。为了更好地研究SOP在系统各种扰动下的动态行为特征,建立了考虑各种控制策略的SOP详细暂态仿真模型,采用基于Krylov子空间的模型降维化简(model order reduction,MOR)方法以提升配电系统的仿真计算效率,并提出新的算法将MOR方法用于变结构配电网络,使其能在多场景下对SOP进行分析。通过IEEE 123算例测试证明,该文方法能够在保证可接受的仿真精度前提下,有效降低整体模型规模,提升仿真计算效率,并满足各种外部扰动场景下的SOP暂态快速仿真分析需求。
