电力系统是一个典型的复杂非线性系统。从理论上讲，非线性方法比线性方法更能准确地描述动态系统，但对于实际电网，通常采用线性方法来近似建模非线性问题。为了研究系统何时可以线性化以及如何准确地线性化系统，提出了一种基于线性系统理论的基于量测的线性化研究方法。
The power system is a typical complex and nonlinear system in nature. Theoretically, the nonlinear approach can describe a dynamic system more accurately than a linear approach, but to an actual power grid, a linear approach was usually used to model a nonlinear problem approximately. To investigate when the system can be linearized and “how small is small” to linearize the system accurately, this paper proposed a measurement-based linearity study approach based on the linear system theory, which utilizes the dynamic responses after events in the actual U.S. Estern Interconnection (EI) power grid and the North-Central China power grid.
