Abstract
In this study, the frequency stability of power system is analyzed and the corresponding control strategy is proposed. In the modern power system, the frequency stability is the key factor to ensure the safe operation of the power grid. This study aims to explore the intrinsic mechanism of frequency instability of power system through theoretical analysis and empirical research, and design effective control strategies to improve system stability. The research method integrates dynamic system theory with advanced control technology, and simulates and analyzes the dynamic behavior of power system by constructing mathematical model. The results show that after adopting the proposed control strategy, the frequency recovery speed and the system stability of the power system are significantly improved in the face of load fluctuation and sudden faults. The innovative point of this study is to propose a strategy based on state estimation and adaptive control, which can monitor the grid state in real time and can adjust the control parameters dynamically, so as to effectively handle various disturbances. The main contribution is to improve the anti-interference ability of the power system to frequency fluctuations, and provide a new technical guarantee for the safe operation of the power grid. Through this study, we provide theoretical and practical guidance for the stable operation of the power system, which is of great significance to the construction of smart grid in the future.
