Power Hardware-in-the-Loop – Emulation of Distribution Grid Challenges at KIT-IEH

​RT Spotlight Zurich - The power hardware-in-the-loop environment at the Institute of Electric Energy Systems and High-Voltage Technology (IEH), KIT, consists of an OP5607 driving two 30 kVA linear 4-quadrantamplifier. Besides other electrical equipment and different devices under test (DUT) it includes the KIT Energy Smart Home Lab, a smart, automated residential building comprising building automation, measurement devices, and different prosumers, allowing for the provision of ancillary grid services. The research focuses on detailed simulation of four wire distribution systems and emulation of challenging situations in those. This implies the analysis of requirements regarding different time scales and system setups as well as a stable and precise loop-feedback with minimal lag. The presentation will present latest results regarding grid simulation and requirements as well as an overview of the system setup at KIT-IEH.
