“…In the previous sections of this paper the influence of the power amplifier was considered as a single time delay. This is very common in literature [12,14]. However, as [11] shows, this simplification results in deviations in comparison to real PHiL simulations.…”

Power Hardware-in-the-Loop (PHiL) simulation is an emerging testing methodology of real hardware equipment within an emulated virtual environment. The closed loop interfacing between the Hardware under Test (HuT) and the Real Time Simulation (RTS) enables a realistic simulation but can also result in an unstable system. In addition to fundamentals in PHiL simulation and interfacing, this paper therefore provides a consistent and comprehensive study of PHiL stability. An analytic analysis is compared with a simulative approach and is supplemented by practical validations of the stability limits in PHiL simulation. Special focus is given on the differences between a switching and a linear amplifier as power interface (PI). Stability limits and the respective factors of influence (e.g., Feedback Current Filtering) are elaborated with a minimal example circuit with voltage-type Ideal Transformer Model (ITM) PHiL interface algorithm (IA). Finally, the findings are transferred to a real low-voltage grid PHiL application with residential load and photovoltaic system.

“…In the last decade a lot of research on PHiL simulation has been performed. Among others, stability analysis of a PHiL simulation at a theoretical basis is shown in [3,[5][6][7][8][9][10][11][12][13] however, Refs. [7,10,11] solely focus on real impedance.…”

“…As a result, linear approximations of them are required, which, in practice means less accuracy in the analysis of PHIL simulation. In the framework of this paper, an analytical approach, extensively described in [22], is briefly presented. The model of a PHIL simulation can be express using transfer function in the frequency domain as shown in Fig.…”

The integration of distributed renewable energy sources and the multi-domain behaviours inside the cyberphysical energy system (smart grids) draws up major challenges.Their validation and roll out requires careful assessment, in term of modelling, simulation and testing. The traditional approach focusing on a particular object, actual hardware or a detailed model, while drastically simplifying the remainder of the system under test, is no longer sufficient. 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 energy system. 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. We investigate the current limitations of HIL techniques and point out necessary future developments. Subsequently, the paper highlights challenges that need specific attention as well as ongoing actions and further research directions.
