“…In [10] the authors present a hybrid modular solid-state transformer for UPS under short-circuit fault in MVDC. The problem of realizing a fault tolerant SST is presented in [11], while in [12] a hybrid DC circuit breaker for MVDC applications is described. In [13], a DC fault ride-through method for MVDC distribution systems is presented.…”

The medium-voltage DC (MVDC) technology has gained increasing interests in recent years. Power electronics devices dominate those 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. 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 Solid State Transformer (SST) and Modular Multilevel Converter (MMC) based Active Front End (AFE). Additional aim of this paper is to supply an 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.

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.

“…Some modeling approaches have been proposed but focus on some specific needs. Small-signal modeling and impedance modeling are used for steady-state stability analysis and control system design but not for EMT simulations [6]- [8]. Averaged-value modeling ignores the internal characteristics of PETs, such as capacitor voltage ripples, transformer voltages and currents, and internal switching stresses.…”
