Abstract
Power system stability is a critical factor in ensuring reliable power supply. With the large-scale integration of renewable energy sources and the widespread application of power electronic devices, the structure and operational characteristics of power systems have undergone significant changes, presenting new challenges to stability analysis and control. This study focuses on the research of power system stability analysis and control strategies, aiming to enhance the stable operation capability of power systems. Based on modern control theory and incorporating artificial intelligence algorithms, this research proposes an online assessment model for power system stability that integrates multi-source data. The model can monitor system states in real-time and predict potential risks. Additionally, an innovative adaptive coordinated control strategy is designed, which optimizes generator output and flexibly adjusts reactive power distribution to effectively suppress low-frequency oscillations and improve transient stability. Simulation results demonstrate that the proposed method significantly enhances system stability under various complex operating conditions, providing theoretical foundations and technical support for constructing a safer and more reliable smart grid.
