摘要:

本文提出了一种混合测量与模型方法,用于近实时估计动态状态雅可比矩阵。该方法计算高效且对网络拓扑变化具有鲁棒性。通过数值示例表明,该方法能够提供良好的动态状态雅可比矩阵估计,并在不可检测的网络拓扑变化下优于基于模型的方法。该方法还可能帮助识别假设网络模型中的显著差异。

英文摘要:

In this paper, a hybrid measurement- and model-based method is proposed which can estimate the dynamic state Jacobian matrix in near real-time. The proposed method is computationally efficient and robust to the variation of network topology. A numerical example is given to show that the proposed method is able to provide good estimation for the dynamic state Jacobian matrix and is superior to the model-based method under undetectable network topology change. The proposed method may also help identify big discrepancy in the assumed network model.
