Résumé:

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.

Résumé:

This paper presents the design and implementation of a digital control system for modular multilevel converters (MMC) and its use in a 5 kW small-scale prototype. To achieve higher system control reliability and multi-functionality, the proposed architecture has been built with an effective split of the control tasks between a master controller and six slave controllers, one for each of the six arms of the converter. The MMC prototype has been used for testing both converter and system-level controls in a reduced-scale laboratory set up of a Multi-Terminal DC transmission network (MTDC). The whole control has been tested to validate the proposed control strategies. The tests performed at system level allowed exploration of the advantages of using an MMC in a MTDC system.

Fast sorting method for balancing capacitor voltages in modular multilevel converters

Résumé:

The modular multilevel converter (MMC) is attracting more and more interest in high-power and high-voltage applications. Highly redundant, each arm of the converter is made of a large number of identical submodules with inner storage capability allowing to reach very high voltage without dc-link capacitor. The control of such a converter represents a challenge when it comes to the implementation of an MMC with a large number of submodules, namely in distributing the control tasks and handling the communicated values in-between controllers and submodules. This paper presents the details of an innovative submodule selection method for the submodule capacitor's voltage balancing within one arm of an MMC. “The Tortoise and the Hare” sorting method shows very fast response, high reliability, and its implementation suits a large number of implemented submodules as for high-voltage dc applications. The proposed submodule capacitor's balancing method is validated on a three-phase 10-kVA prototype with five submodules per arm.

Enabling MVDC PV collection grids with modular solid state transformers

Résumé:

Solar energy is typically collected through AC grids because of strong reliability and availability of standard solutions. The introduction of Solid State Transformers may not only allow reducing footprint and losses, but also implement peak shaving capabilities and the injection to MVDC grids directly. This work proposes an innovative PV energy collecting strategy with modular isolated DC/DC converters.

Résumé:

This paper proposes a DC electric energy distribution scheme for data centers. Most state-of-the-art data centers use AC distribution at all voltage levels, from MV at the feeder substation down to the 380 VAC indoor distribution level for direct connection of IT racks. This paper provides a DC distribution scheme that is equivalent to state-of-the-art AC distribution systems in terms of specific and very stringent availability and reliability requirements. It features significant benefits in terms of efficiency and controllability and focuses specifically on the integration of solar power, fuel cells, and battery-based UPS, with the MV Solid State Transformer (“SST”) as the enabling technology. The proposed DC distribution scheme provides flexible solution for future green data centers committed to the 2030 Sustainability Roadmap – 100% supply from renewable energy sources at any hour.

Résumé:

In the frame of a collaboration project within Swiss Competence Centre for Energy Research, a Multi Terminal DC pilot has been implemented. For the interaction with the medium voltage AC grid, a Modular Multilevel Converter has been designed for its features in low harmonic content, scalability, and flexibility. The control of converters in the MTDC network implements a non-dead band voltage control. The Energy buffering of the MMC converter will allow the converter to sustain either AC or DC grids. The operation of the MMC converter in an MTDC network containing three converter is verified experimentally in a reduced-scale pilot.
