An expandable distributed power hardware-in-the-loop agent system (vPHILAS) that interacts across laboratory boundaries (worldwide) is to be set up at Munich University of Applied Sciences (HM). The planned vPHILAS enables the emulation, analysis and optimization of the future electric energy system (DC, AC and hybrid system) and its participants through interaction and coupling of a real-time grid simulator (RNS) with any number of power hardware-in-the-loop agents (PHILA). For this purpose, existing laboratory test benches are integrated into a PHILA as devices-under-test (DUT; e.g. wind power, PV & HVDC emulators) with the help of a grid emulator (NE). Further PHILAs are linked together across laboratories and worldwide via the Internet using a grid emulator interface (NEI; a software and hardware interface to be developed/built) in a modular and flexible manner to form an electrical energy system of any size.

The RNS simulates the grid under test (grid-under-test (GUT)) with several grid nodes (GUT nodes). Individual grid nodes are represented in real terms by scaled PHILAs, which are “connected” to the GUT either via grid emulators (e.g. NE1 & NE2) or NEI and thus physically react to the simulated grid voltages of the corresponding GUT nodes. The individual PHILAs do not exchange energy with each other, but are connected to the RNS via NE/NEI in such a way that realistic setpoint values of the grid voltages are transferred from the RNS to NE or NEI and simulated there. These voltages simulated in the NE or NEI have a real and physical effect at the respective GUT node on one or more DUTs to be tested, which respond with currents. This creates a real power and current flow in the PHILA between the DUT and NE/NEI. The real flowing currents and generated voltages in the NE/NEI are fed back to the RNS, which updates and continues its simulation of the GUT. This creates a feedback system that links PHILAs (or even other vPHILAS) across laboratories within the HM but also worldwide and enables a scaled but realistic emulation, analysis and optimization of hybrid AC/DC electrical energy systems (e.g. three-phase four-wire systems (AC) or two-pole + protective conductor systems (DC)).
