“…Figure 3 shows that the dynamics of the SST cell model correspond, to a fair extent, to a real DAB-based SST converter. When compared to real hardware results from a built SST demonstrator as in [30], the voltage controller's time responses correspond well enough to perform system-level studies. Another comparison is made between switching model and average model as in Figure 4, showing the dynamic accuracy and strong gain in computation time, as measured between a detailed switching model and the RMS average model, at the same simulation pace.…”

Medium-voltage DC (MVDC) technology has gained increasing attention in recent years. Power electronics devices dominate these grids. Accurate simulation of such a grid, with detailed models of switching semiconductors, can quickly became very time-consuming, according to the number of connected devices to be simulated. A simulation approach based on interactions on a continuous time model can be very interesting, especially for developing a system-level control model of such a modern MVDC distribution grid. The aim of this paper is to present all the steps required for obtaining a continuous time modelling of a +/−10 kV MVDC grid case study, including a solid-state transformer (SST)- and modular multilevel converter (MMC)-based active front end (AFE). An additional aim of this paper is to supply educational content about the use of the continuous time simulation approach, thanks to a detailed description of the various devices modelled into the presented MVDC grid. The results of a certain number of simulation scenarios are eventually presented.
