Feasibility of geographically distributed real-time simulation of HVDC system interconnected with AC networks

Numerical simulation is an essential tool to study and design HVDC grids interconnected with AC networks. Detailed real-time simulation of such complex power systems requires large computational resources. The connection of remote laboratories provides the possibility to share available resources thus meeting these demanding computational requirements. This concept is referred to as geographically distributed simulation. This paper presents a feasibility study of geographically distributed real-time simulation realized through the connection of two OPAL-RT real-time digital simulators, located at SINTEF (Trondheim, Norway) and ACS (RWTH Aachen University, Germany). A simple HVDC point to point link that connects two AC systems is adopted here as a study.
