Abstract
This article comprehensively explores the analysis and control issues of frequency stability in power systems. The article first elaborates on the background and significance of frequency stability research in power systems, summarizes the current research status, and proposes research methods and technical routes. In the theoretical foundation section, the article deeply analyzes the frequency dynamic characteristics of the power system, studies various factors that affect frequency stability, and constructs corresponding mathematical models. This provides a solid theoretical foundation for subsequent analysis and control. In terms of analysis methods, the article adopts various approaches such as time-domain simulation based frequency stability evaluation, frequency-domain analysis method, and data-driven frequency stability prediction method to comprehensively evaluate the frequency stability of the power system. The article proposes an optimization and improvement scheme for the traditional frequency control method, explores a new frequency control strategy under the integration of new energy, and constructs a multi time scale coordinated frequency control system. These strategies and methods aim to improve the frequency stability of the power system and ensure its safe and stable operation. This study not only provides a comprehensive perspective and method for the analysis and control of frequency stability in power systems, but also provides important theoretical basis and practical guidance for the planning, operation, and scheduling of power systems.
