Study the dynamic behavior of disturbance propagation is of great importance for the safety and stability of power system. The dynamic analysis of the disturbance of the power system attempts to use an mature epidemic model of biology and open a new path to the dynamics of disturbance propagation. In this paper, based on the analogy epidemic model and the propagation of the grid disturbance, the concept of disturbance propagation intensity was put forward. Furthermore, the complex network theory was used to analyze the complex network topology of the power system, and the random matrix theory was used to analyze the relationship between the spatial and temporal data in power system. At last, the dynamic model of disturbance propagation in power system based on data-driven was established. The simulation shows that the proposed model can effectively supplement the traditional power system disturbance propagation analysis, and can analyze the dynamic behavior of power system.
