Abstract
This article delves into the impact of large-scale wind power integration on grid stability, including frequency stability, voltage stability, and transient stability. Firstly, the article provides an overview of the research background and significance, as well as the current research status in this field both domestically and internationally, clarifying the research methods and technical roadmap. In terms of frequency stability, the article analyzed the fluctuation characteristics of wind power output, evaluated the frequency regulation capability, and pointed out the frequency stability risks that large-scale wind power grid connection may bring. In order to gain a deeper understanding of the impact of wind power integration on grid voltage stability, this article studied the reactive power characteristics of wind farms, constructed a voltage stability evaluation index system, and analyzed voltage stability under different wind power penetration rates. In addition, the article also focuses on the impact of wind power grid connection on the transient stability of the power system. By analyzing the fault ride through capability of wind turbines, a transient stability simulation model was constructed, and the transient stability of large-scale wind power grid connection was evaluated. This study not only provides a comprehensive and in-depth perspective on the impact of large-scale wind power grid integration on grid stability, but also provides important theoretical basis and practical guidance for wind power grid integration planning, operation, and control, which is of great significance for promoting the sustainable development of the wind power industry.
