VSC HVDC converter stations are very complex systems that are able to provide a highly dynamic response to system events. These converters make use of multiple dedicated control loops and protection systems to allow for this dynamic response. To protect the vendor's IP, only proprietary black (or grey) box models are available, limiting the ability of the HVDC owner to obtain a full image of the behavior of the equipment and its interaction with other equipment. As a result, many system operators revert to the use of dedicated replica (hardware) models of the converters connected to a (real-time) simulator. This panel discusses the pros and cons of this approach, and will show best practices by different users.
