English: With the global transition toward low-carbon energy systems and the rapid development of renewable energy, modern power systems are experiencing fundamental changes characterized by large-scale renewable energy integration, long-distance bulk power transmission, regional power interconnection, and increasing penetration of power electronic devices. HVDC and UHVDC transmission technologies offer significant advantages in long-distance high-capacity power delivery, asynchronous grid interconnection, flexible power flow control, and efficient integration of large-scale renewable energy bases and offshore wind power. This track focuses on advanced HVDC transmission systems and converter technologies for renewable-dominated power systems. It aims to provide a platform for in-depth discussions on LCC-HVDC, VSC-HVDC, hybrid HVDC transmission, multi-terminal HVDC, multi-infeed HVDC, and improved LCC converter topologies such as CLCC, SLCC, and CCC. Key topics include commutation failure mitigation, weak-grid adaptability, fault ride-through, DC protection, coordinated operation of AC/DC hybrid systems, renewable energy transmission, and practical engineering applications. The track seeks to promote theoretical innovation, key equipment development, control and protection technologies, and practical experience sharing for the development of secure, low-carbon, efficient, and flexible future power systems.
