Abstract
This article delves into the stability analysis and control strategies of high-voltage direct current transmission systems, aiming to provide theoretical support and practical guidance for the stable operation of power systems. The article first outlines the research background of the stability of high-voltage direct current transmission systems and the significance of their control strategies, while also reviewing the current research status in this field both domestically and internationally. In the stability mechanism analysis section, the article studied in detail the dynamic characteristics of DC transmission systems, explored the impact of converter station operation on system stability, and deeply analyzed the mechanism of interaction between AC and DC systems, providing a theoretical basis for subsequent stability evaluation and control strategy optimization. The article proposes stability assessment methods based on time-domain simulation, small signal stability analysis, and large disturbance stability criteria, providing comprehensive technical means for the stability assessment of high-voltage direct current transmission systems. In terms of control strategy optimization, the article analyzes the limitations of traditional control strategies and improves them based on intelligent algorithms. At the same time, a multi-ob jective coordinated control strategy is designed to improve the stability and operational efficiency of high-voltage direct current transmission systems. This study not only enriches the theoretical system of stability analysis and control strategies for high-voltage direct current transmission systems, but also provides important technical support and decision-making basis for the safe and stable operation of power systems.
