HVDC transmission systems have increasingly been used in modern power transmission networks due to their numerous advantages such as providing higher power transmission capacity over long distances, and interconnecting asynchronous systems. With the increasing deployment of DC transmission in existing AC networks, the possibility of AC and DC circuits running parallel to each other and sharing the same right-of-way or even the same tower is increasing, and hence hybrid AC/DC power grids are rapidly developing. The characteristics of hybrid AC/DC grids and conventional AC grids are different in various aspects. The non-complex controllability of HVDC systems provides a new choice for control of hybrid AC/DC power grids. However, currently, the HVDC control systems are not fully involved in the power flow and stability of hybrid power grids. In addition, the use of power electronic devices with limited thermal overload capability in HVDC technology reduces the overload capability of HVDC converters. This significantly influences the fault current level of the whole network. While the number of AC/DC interconnections gradually increases in the hybrid grids, the mutual influence between AC and DC systems becomes more pronounced. Therefore, hybrid AC/DC grids encounter new control and protection challenges. This special session is dedicated to identifying, addressing, and disseminating state-of-the-art research works in the field of hybrid AC/DC transmission systems.
Topics of interest for this special session include, but are not limited to:
- Methodologies for planning and operating hybrid AC/DC grids - Modelling and analysis of electromechanical dynamics in hybrid AC/DC grids - Co-simulation and hardware-in-the-loop simulations as a tool for the validation, testing, and verification of hybrid AC/DC grids - Methods for monitoring and control of dynamic and transient stability of hybrid grids - Innovations on the protection of hybrid grids including AC and DC fault ride-through techniques - Novel approaches for commutation failure and cascading fault inhibition in hybrid AC/DC grids including LCCs - Design, control, and protection of power converter technologies (LCC, VSC, and MMC) - Advances in power apparatus enabling development and enhanced features in hybrid AC/DC grids such as DC transformers and DC circuit breakers - Advanced synchronization schemes for enhancing dynamics response and stability - New techniques of blackout restoration in the context of hybrid AC/DC grids.
