Power Grid Disturbance Prediction and Analysis Method Based on SIR Model

With the continuous development of the times and the continuous improvement of people's living standards, the power system is also keeping pace with the times. At the same time, the transmission of power grid disturbance is becoming more and more obvious. If we can't analyze the power grid disturbance in the process of power grid transmission, it will lead to the chain accident of power grid or large-scale power outage of power grid. This paper mainly studies the disturbance propagation characteristics of power grid, which has an important impact on the security and stability of power system. This paper cites the mature SIR model in the field of biology and combines it with the disturbance propagation of the power grid. By analyzing the model and analogy to the disturbance propagation of the power grid, this paper analyzes the impact of the disturbance propagation of the power grid on the stability of the power system, which makes it easier to further track and locate the disturbance source and give a first warning of the degree of the disturbance of the power grid, The model simulation shows that the scheme can effectively deal with the impact of disturbance propagation and make the power system operate more safely and stably.
