Abstract
High-voltage direct current (HVDC) transmission systems, as a key technology in modern power networks, play a critical role in ensuring the safe operation of the grid. This paper investigates the dynamic characteristics and control issues of HVDC transmission systems with the aim of enhancing their stability and control performance. Based on nonlinear dynamics theory and modern control methodologies, an improved adaptive robust control strategy is proposed, which effectively addresses the impacts of system parameter uncertainties and external disturbances. By developing an accurate mathematical model and conducting simulation analyses, the applicability and superiority of the proposed method under various operating conditions are validated. The research findings indicate that the designed controller not only significantly strengthens the transient stability of the system but also greatly improves the precision of steady-state operation. Additionally, this study innovatively incorporates intelligent optimization algorithms for optimizing controller parameters, thereby further enhancing the overall performance of the system. The final conclusion demonstrates that this approach provides an efficient and reliable solution for stability analysis and control of HVDC transmission systems, possessing significant theoretical value and promising engineering application prospects.
