    • HVDC-based modular multilevel converter in the STATCOM operation mode 

      Antonio Ferreira, Abel; Gomis Bellmunt, Oriol; Teixidó Román, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In a futuristic vision, deeply interconnected ac and dc networks are expected, which would be restructured over the time in order to maximize the power transmission efficiency. In some grid configurations, grid-tied inverters ...

    • Impact of the DC cable models on the SVD analysis of a multi-terminal HVDC system 

      Akkari, Samy; Prieto-Araujo, E.; Jing, Dai; Gomis Bellmunt, Oriol; Guillaud, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés obert
      High Voltage Direct Current (HVDC) grids are complex Multi-Inputs Multi-Outputs (MIMO) systems whose dynamics are difficult to assess. This paper first describes the modelling of VSC-based Multi-Terminal HVDC systems (MTDC) ...

    • Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters 

      Suul, Jon Are; D'Arco, Salvatore; Rodríguez Cortés, Pedro; Molinas Cabrera, Marta (2016-05-12)
      Article
      Accés obert
      This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference ...

    • Multi-terminal HVDC grids with inertia mimicry capability 

      Zhang, Weiyi; Rouzbehi, Kumars; Luna Alloza, Álvaro; Gharehpetian, Gevorg B.; Rodríguez Cortés, Pedro (2016-06-23)
      Article
      Accés obert
      The high-voltage multi-terminal dc (MTDC) systems are foreseen to experience an important development in the next years. Currently, they have appeared to be a prevailing technical and economical solution for harvesting ...

    • Power control of VSC HVDC converters for limiting the influence of ac unbalanced faults on multi-terminal DC grids 

      Suul, Jon Are; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      It will be important for the operation of future multi-terminal HVDC systems that each converter unit is capable of limiting the influence of nearby AC faults on the DC grid. Thus, the local control systems at each terminal ...

    • Primary and secondary power control of multiterminal HVDC grids 

      Egea Àlvarez, Agustí; Beerten, J; Van Hertem, Dirk; Gomis Bellmunt, Oriol (2010)
