Abstract:The framework for virtual integration of laboratories enables co-simulation and joint experiments that include hardware and software resources hosted at geographically distributed laboratories. The underlying concept of such framework is geographically distributed real-time (RT) co-simulation. To this end, digital RT simulators are interfaced over long distances via shared communication network such as the Internet. This study proposes an architecture for a modular framework supporting virtual integration of laboratories that enable flexible integration of digital RT simulators across Europe. In addition, the framework includes an interface that enables access for third parties via a web browser. A co-simulation interface algorithm adopted in this study is based on representation of interface quantities in form of dynamic phasors. Time delay between RT digital simulators is compensated by means of phase shift that enables simulation fidelity for slow transients.
Global Real-Time Super Laboratory (Global RT-Super Lab) represents a vendor-neutral distributed platform established based on virtual interconnection of Digital Real-Time Simulators (DRTS) and Hardware-In-the-Loop (HIL) setups hosted at eight geographically distributed laboratories located in the USA and Europe. This article describes the efforts towards the realization of this large-scale virtual infrastructure and demonstration of the multi-lab setup for simulation and testing of next generation global power grids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
