“…The study was presented concurrently with the preliminary results of the work presented in this manuscript [19]. The current work features a modular and generic sorting algorithm that is easily extendable and is based on logic sorting rather than a PI controller as proposed in [18]. The real-time emulation in this paper, is a novel implementation of a CHIL emulation of a MMC-BESS and an extension of our work presented in [19], to validate motor real-time operation compared to a prototype MMC-BESS.…”

“…The Mission Profile Emulator of MMC-BESS was previously studied using a full-bridge converter to emulate the arm current, without incorporating the batteries model [17]. Another study proposed the realtime operation of the MMC-BESS using the state space model of the converter and a lookup table method [18]. The study was presented concurrently with the preliminary results of the work presented in this manuscript [19].…”

This paper details a validated real-time emulation of a modular multilevel converter with integrated energy storage sub-modules. The real-time emulated system is implemented using MicroLabBox/ dSPACE. A validation is carried out by constructing and testing a prototype of the converter with a reduced number of voltage levels and integrated batteries. The real-time operation of the emulated converter is tested under a range of loading conditions and compared to the prototype. Emulated results closely match the physical prototype results. Based on this outcome, a converter that comprises a high number of sub-modules is emulated and investigated when connected to a large scale motor. This research provided a seamless extension of the model from a lower to a higher number of converter sub-modules with minor changes in the emulation structure, the basic control and the sorting algorithm. This is a novel real-time emulation of the converter that can be used for electric vehicle application using MicroLabBox/dSPACE.
