      This paper presents a grid current control of a grid connected Voltage Source Converter (VSC) with an LCL filter. The control method enables to shape the input admittance of the converter in addition to track a given current ...
    • Active damping: an Hinf model reference approach 

      Pérez, Jorge; Cóbreces Álvarez, Santiago; Griñó Cubero, Robert; Huerta, Francisco; Rodríguez, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2018-08-01)
      Article
      Accés obert
      This paper focuses on the design of an active-damping controller that shapes the dynamics of an LCL grid connected voltage source converter (VSC) to mimic an L-filter connected VSC. This makes possible to use simpler ...
    • Admittance-shaped Hinf current controller for grid-connected VSC 

      Perez Morales, Jorge; Cóbreces Álvarez, Santiago; Griñó Cubero, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper introduces an H8 current controller that allows the shaping of power converters’ input admittance in frequency domain, allowing to define not only its magnitude but also its phase. In addition to admittance ...
