论文摘要
本文提出了一种基于全体形态嵌入（HE）进行电压稳定性分析的网络解耦方法。使用所提出的HE方法，它具有物理负载缩放系数S，它在目标总线和秋千总线之间开发了一组脱钩的两驾驶室电路通道。因此，在每个通道中引入了一个名为σ（S）的复杂值的虚拟指数，以评估具有准确性的前瞻性工作条件的电压稳定性。然后，可以通过可视化电压塌陷的统一边界在σ平面上可视化其各自的σ索引来分析每个总线处的稳定缘。此外，从物理载荷中嵌入的嵌入中，可以分析有关缩放因子s的操作条件变化的每个总线的σ（s）轨迹。在IEEE 14-BUS Power System上验证了建议的网络解耦方法的有效性。
This paper proposes a network decoupling method based on Holomorphic Embedding (HE) for voltage stability analysis. Using the proposed HE method with a physical load scaling factor s, it develops a set of decoupled two-bus circuit channels between a target bus and the swing bus. Accordingly, a complex-valued virtual index, named σ(s), is introduced in each channel to assess the voltage stability of prospective operating conditions with ensured accuracy. Then the stability margin at each bus can be analyzed by visualizing its respective σ(s) index on the σ plane with a unified boundary of voltage collapse. Moreover, benefitted by the embedding with physical loading, the trajectory of σ(s) for each bus with the variation of operating conditions can be analytically given about the scaling factor s. The effectiveness of proposed network decoupling method is verified on the IEEE 14-bus power system.
