[article]
2017
arXiv
pre-print
Preserved Fulltext
This paper aims to provide an overview of the present status-quo of real-time and HIL approaches used for smart grids and their readiness for cyber-physical experiments. ...
Real-time simulation and Hardware-in-the-Loop (HIL) techniques emerge as indispensable tools for validating the behaviour of renewable sources as well as their impact/interaction to with the cyber-physical ...
In this approach, the non-real-time simulation model is converted to FMU and integrated directly to the real-time simulators model and is forced to run at real-time simulators time steps. ...
