Presentation Description: Multi-terminal HVDC transmission technology offers significant benefits to integrating large scale and remote renewables into the incumbent transmission grid. This presentation discusses the key components needed to build such grids such as VSC converters and different types of HVDC circuit breakers. A guide will be provided on how these components can be combined to achieve desired system performance, and what factors influence the main design choices. The principles behind coordinating the HVDC system protection with onshore AC grid operation in terms of maximum loss of infeed will be explained. An overview and comparison will be given of the existing multi-terminal grid developments worldwide. The technology readiness of key components, and the remaining challenges regarding standardization and coordination will be discussed. Based on this, an overview will be presented of current multi-terminal HVDC developments/initiatives in the US.
Learning Objectives:
Upon completion, the participant will have an understanding of how HVDC technology can be used to create multiterminal HVDC systems, the key components, and system performance
Upon completion, the participant will have an understanding of how multiterminal HVDC systems can be used to integrate large amounts of renewable energy over long distances and reinforce the existing onshore transmission grid cost effectively and with the lowest environmental impact
The participant will have an overview of currently existing multi-terminal HVDC networks worldwide, and an understanding of the potential benefits in US applications
