Enhancing Grid Resilience with HVDC and FACTS

This panel will review positive impacts of HVDC and FACTS have on system resilience. Potential vulnerabilities of the bulk power system through the interconnected nature ac systems as well as through SCADA and other communication systems will be reviewed. Followed by a discussion of how FACTS and HVDC protection, control, and communication systems differ from those for conventional ac systems. HVDC and FACTS systems also have the ability to improve the resilience of the bulk power system. FACTS devices, LCC HVDC systems, VSC-based systems, and multiterminal DC grids will be compared in terms of their abilities to impact system resilience in the face of major disturbances or cyber-physical events. Potential detection and mitigation ideas will be presented. Example case studies based on existing or proposed systems will be presented.
