Multi-terminal high voltage direct current (MTDC) grids, or supergrids, are considered an interesting solution to integrate large amounts of renewable power and release congestion of existing AC power grids. Nonetheless, safe and reliable operation of such grids require the development of new DC protection systems.
The scope of this thesis includes control and management of the Modular Multilevel Converter (MMC)-based Multi-Terminal Direct Current (MTDC).
PhD Swann GASNIER “Decision support framework for offshore wind farm electrical networks: Robust design and assessment under uncertainties’’
Large offshore wind farms will be important players within the future energy landscape. What is the expected benefit for a project is an essential issue from Investor side, considering both technical and economic aspects. Levelized Cost Of Energy - LCOE - is a standard economic indicator which allows to assess the economic viability of a project.
This paper describes the influence of grounding on voltage and current transients during DC-link fault in a High Voltage Direct Current (HVDC) cable system.
Due to the complexity of the system, the control of the Modular Multilevel Converter (MMC) constitutes an intensive research activity.
The Modular Multilevel Converters (MMCs) have emerged as the most suitable converter technology for HVDC application.
A protection strategy for high voltage direct current grids using superconducting fault current limiters as main protection component is presented in this work.
