    • Dc voltage droop control design for mmc-based multiterminal hvdc grids 

      Dadjo Tavakoli, Saman; Sánchez Sánchez, Enric; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-20)
      Article
      Open Access
      This article addresses the design of the DC voltage droop control in modular multilevel converter (MMC)-based multiterminal HVDC grids. First, two energy-based control approaches, namely classic and cross control, are ...
    • Fault ride-through control based on voltage prioritization for grid-forming converters 

      Dadjo Tavakoli, Saman; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol; Galceran Arellano, Samuel (2023-01-01)
      Article
      Open Access
      This paper discusses that the existing grid codes on the fault ride-through (FRT) opera-tion have certain complications to be implemented in the grid-forming (GFM) converters.In particular, they do not provide a clear ...
    • Grid-forming services from hydrogen electrolyzers 

      Dadjo Tavakoli, Saman; Ghazavidozein, Mehdi; Albernaz Lacerda Freitas, Vinícius; Cheah Mañé, Marc; Prieto Araujo, Eduardo; Mancarella, Pierluigi; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2023-01-01)
      Article
      Open Access
      Hydrogen electrloyzers are power-to-gas storage devices that can facilitate large-scale integration of intermittent renewable sources into the future power systems. Due to their fast response and capability to operate in ...
    • Interaction assessment and stability analysis of the MMC-based VSC-HVDC link 

      Dadjo Tavakoli, Saman; Prieto Araujo, Eduardo; Sánchez Sánchez, Enric; Gomis Bellmunt, Oriol (2020-04-21)
      Article
      Open Access
      This paper investigates the dynamic behavior of a modular multi-level converter (MMC)-based HVDC link. An overall state-space model is developed to identify the system critical modes, considering the dynamics of the master ...
    • Mutual interactions and stability analysis of bipolar DC microgrids 

      Dadjo Tavakoli, Saman; Zhang, Peng; Lu, Xiaonan (CSEE, 2019-12-11)
      Article
      Open Access
      This paper presents an Multi-Input Multi-Output (MIMO) analysis to investigate the mutual interactions and small-signal stability of bipolar-type dc microgrids. Since bipolar dc microgrid is replete with power-electronic ...
