Distributed real-time co-simulation as a service

The increase of faster dynamics in power systems has led to growing interest in new simulation solutions, especially in the field of hardware-in-the-loop and real-time simulation. Due to the size of power systems, detailed simulation of the faster dynamics is only feasible for a section of the system, whereas the rest is usually modeled as an infinite power bus. The aim of this work is to present a solution which would allow the representation of a significant portion of the dynamics that are usually not captured by the infinite power bus approach and enable the joint simulation among multiple simulation laboratories to share this dynamic model of the network beyond the boundaries of the detailed simulation. Furthermore, the presented architecture should allow the virtualization of each of these laboratories in cases where this coarse model of the neighboring grid sections is sufficient. First distributed simulation examples show the current status of our implementation of the architecture presented here.
