From Monolithic To Geographically Distributed Simulation Of Hvdc Systems

Virtual interconnection of laboratories is a novel methodology for realization of large-scale simulation and testing infrastructures based on connection of hardware and software resources at geographically dispersed laboratories. The underlying concept of virtual interconnection of laboratories is Geographically Distributed Real-Time Simulation (GD-RTS). This paper focuses on GD-RTS of a High Voltage direct current (HVdc) link with a partitioning point at a dc cable. A co-simulation Interface Algorithm (IA) and a start-up procedure that together preserve simulation stability are introduced. Proposed guidelines are verified for GD-RTS of an HVdc link that interconnects transmission system benchmark model proposed by Council on Large Electric Systems (CIGRE) and a simplified representation of an offshore wind farm.
