Study on the Influence of Wind Power Uncertainty on Dynamic Stability of Power System

Abstract

Due to the uncertainty of wind power generation, the access of high proportion of wind power has a negligible impact on grid operation. This paper analyzes the mathematical model of each part of wind power plant by modeling, analyzing the main influence of wind power uncertainty on the power grid, using Hexi power grid as background, using PSASP software to simulate and analyze the impact load of the power grid and the impact load at the same time and fluctuations in system voltage under gust disturbances. The simulation results indicate the risk indicators of the system's anti-interference ability
