Abstract
High-voltage direct current (HVDC) transmission systems, as a critical component of modern power transmission, play a significant role in enhancing the stability and efficiency of power systems. With the widespread application of renewable energy and the continuous expansion of grid scale, traditional AC transmission methods face numerous challenges. HVDC transmission, characterized by its advantages of long-distance, high-capacity, and low-loss transmission, has emerged as a key technology to address these issues. This study delves into the control strategies for HVDC transmission systems and proposes a novel approach that integrates adaptive fuzzy control with predictive control to achieve precise control of system dynamic characteristics under complex operating conditions. By establishing detailed mathematical models and incorporating actual engineering data, this method effectively mitigates the impact of nonlinear factors and uncertain disturbances, significantly improving system robustness and response speed. Simulation results demonstrate that under various operating conditions, the proposed control strategy maintains excellent steady-state performance and transient characteristics, reducing voltage fluctuation amplitude by approximately 30% and increasing power transmission efficiency by more than 15% compared to traditional PID control methods. Additionally, this research introduces multi-ob jective optimization algorithms to perform global optimization of controller parameters, further enhancing overall system performance. This innovative research not only provides theoretical foundations and technical support for the optimal design of HVDC transmission systems but also lays a solid groundwork for the development of future smart grids.
