  For robust testing of new technologies used in future, intelligent power and
energy systems, realistic testing environments are needed. Due to the
dimensions of a real-world environment a field-based installation is often not
viable. More efficient instead of a local installation is to connect existing
and highly sophisticated labs with different focus of specialization. Today's
experimental setups for the Smart Grid domain are very time-consuming solutions
or specific implementations for a single project. To overcome this challenge,
an innovative concept for a novel approach for large-scale co-simulation across
locations (different labs) is presented in this paper.
