    • Caracterització i estudi d’enllaços HVDC 

      Almirall Lloret, Joan (Universitat Politècnica de Catalunya, 2021-07-05)
      Bachelor thesis
      Open Access
      El present document es presenta com: caracterització i estudi sobre la tecnologia d’enllaços HVDC, d’acord al seu títol. Primerament s’estudien els enllaços d’una manera genèrica a través d’una introducció històrica que ...

    • Circulating current control and evaluation of carrier dispositions in modular multilevel converters 

      Darus, Rosheila; Pou Félix, Josep; Konstantinou, Georgios; Ceballos Recio, Salvador; Agelidis, Vassilios (2013)
      Conference report
      Restricted access - publisher's policy
      This paper presents two control techniques to minimize the circulating currents of the modular multilevel converter. The control techniques reduce the amplitude of each capacitor voltage ripple. Multicarrier level-shifted ...

    • Convertidor dc-dc elevador en modo interleaving 

      Rodríguez Navarro, Víctor (Universitat Politècnica de Catalunya, 2015-06)
      Bachelor thesis
      Restricted access - author's decision
      Este proyecto se basa en la conexión de un módulo de supercondensadores a una red de corriente continua, con la finalidad de absorber y entregar potencia con una dinámica mucho más rápida de la que sería capaz de aportar ...

    • Estudi de transmissió en corrent continu amb convertidors LCC 

      Molio Dolezal, Marc Antoni (Universitat Politècnica de Catalunya, 2015-06-10)
      Bachelor thesis
      Open Access

    • 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)
      Conference report
      Restricted access - publisher's policy
      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 ...

    • Passivity-based control of multi-terminal HVDC systems under control saturation constraints 

      Dòria Cerezo, Arnau; Olm Miras, Josep Maria; Scherpen, Jacquelien M.A. (2015)
      Conference report
      Restricted access - publisher's policy
      This paper proposes a decentralized, passivity-based cont rol design for power stations in a multi-terminal High Voltage Direct Current transmissi on system. The control algorithm is shown to asymptotically stabilize the ...

    • Positive- and negative-sequence control of grid-connected photovoltaic systems under unbalanced voltage conditions 

      Mirhosseini, Mitra; Pou Félix, Josep; Karanayil, Baburaj; Agelidis, Vassilios (2013)
      Conference report
      Open Access
      This paper discusses the control of the positive- and negative-sequence components of a large-scale grid-connected photovoltaic system (GCPS) under unbalanced voltage sag conditions in the grid. Some issues regarding ...
