Abstract
The stability of power system is vital to national economy and people's life. Faced with new energy access, complicated load and huge power grid structure, the traditional analysis methods face challenges. This study focuses on the stability analysis and control strategy of the power system, and explores the methods to adapt to the modern power system. By establishing a model containing various power sources and complex loads, combining time domain simulation and eigenvalue analysis, the system stability is deeply analyzed, and the control parameters are optimized with intelligent algorithm. The research shows that the proposed method can accurately evaluate the stability of the system, and put forward a multi-target coordinated control strategy, and effectively improve the transient stability and voltage stability, especially in dealing with the power fluctuations caused by large-scale wind power grid connection. This study provides theoretical and technical support for the safe and stable operation of the power system, innovatively applies the intelligent optimization algorithm to the stability control, and provides new ideas for the subsequent research.
