    • 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 ...
    • 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 ...
    • Methodology for interaction identification in modular multi-level converter-based HVDC systems 

      Dadjo Tavakoli, Saman; Prieto Araujo, Eduardo; Sánchez Sánchez, Enric; Gomis-Bellmunt, Oriol (2021-07-24)
      Article
      Restricted access - publisher's policy
      This paper suggests a methodology for the identification, classification, and evaluation of various types of interactions that may occur in an HVDC link based on modular multi-level converters (MMC). The methodology ...
    • 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 ...
    • Optimal H-infinity control design for MMC-based HVDC links 

      Dadjo Tavakoli, Saman; Fekriasl, Sajjad; Prieto Araujo, Eduardo; Beerten, Jef; Gomis Bellmunt, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2021-04-06)
      Article
      Open Access
      The modular multilevel converter (MMC) has emerged as the preferred choice for voltage source converter (VSC)-based high voltage direct current (HVDC) systems due to its low losses, low harmonic distortion, modularity, and ...
