Two-stage network processor for an independent HVDC grid supervisory control

摘要: This paper proposes a two-stage network processor for the supervisory control of multi-terminal HVDC grid that connects different AC areas. The proposed processes DC substation topology locally in first stage and analyzes connectivity at controller. uses k-means clustering method to detect islands prepares required information carry out converter mode assignation. performance has been tested an islading scenario 7-terminal using real-time co-simulation platform. output helps application level make decisions based on modes available converters islands. architecture compared with centralized terms computational complexity.
