摘要:

本文提出了一种新的数据驱动技术,用于基于Koopman模式分解计算非线性系统的参与因子。在满足某些条件的情况下,该技术能够推广原始线性模态-状态参与因子的定义。通过两个数值例子展示了该方法的性能:一个基于标准非线性动力学系统,另一个基于两区域四机电力系统。Koopman模式分解能够处理一大类非线性,因此该技术能够处理由于非线性引起的实际振荡,同时计算速度快且兼容实时应用。

英文摘要:

This paper develops a novel data-driven technique to compute the participation factors for nonlinear systems based on the Koopman mode decomposition. Provided that certain conditions are satisfied, it is shown that the proposed technique generalizes the original definition of the linear mode-in-state participation factors. Two numerical examples are provided to demonstrate the performance of our approach: one relying on a canonical nonlinear dynamical system, and the other based on the two-area four-machine power system. The Koopman mode decomposition is capable of coping with a large class of nonlinearity, thereby making our technique able to deal with oscillations arising in practice due to nonlinearities while being fast to compute and compatible with real-time applications.
