Abstract
The transient stability of power systems is a critical issue for ensuring the safe operation of the grid. With the integration of renewable energy and changes in load characteristics, traditional analysis and control methods are facing new challenges. This study aims to enhance the transient stability of power systems by conducting an in-depth investigation into modeling, analysis, and control under complex dynamic conditions. By incorporating nonlinear dynamics theory and modern optimization algorithms, a transient stability assessment method based on wide-area measurement information is proposed, which can more accurately predict system behavior under large disturbances. Additionally, an adaptive coordinated controller is designed, integrating Power System Stabilizers (PSS) with Flexible Alternating Current Transmission Systems (FACTS) devices, significantly improving the system's disturbance resistance and recovery performance. The results demonstrate that the proposed method exhibits superior stability and robustness in multi-machine system simulations, particularly in scenarios with high penetration of renewable energy. The primary innovation of this research lies in combining data-driven approaches with physical models, overcoming the limitations of traditional methods under complex operating conditions, and providing theoretical support and technical references for practical engineering applications. This study holds significant implications for advancing smart grid technologies.
