    • Decoupled simultaneous complex power sharing and voltage regulation in islanded AC microgrids 

      Duarte Mejia, Josue Neftali; Velasco García, Manel; Martí Colom, Pau; Camacho Santiago, Antonio; Miret Tomàs, Jaume; Alfaro Aragón, Carlos Arturo (Institute of Electrical and Electronics Engineers (IEEE), 2023-04)
      Article
      Accés restringit per política de l'editorial
      In islanded AC microgrids, when multiple voltage source inverters (VSIs) operate in parallel, it is challenging to simultaneously obtain both accurate complex (active and reactive) power sharing and voltage regulation (in ...
    • Constrained predictive control based on a large-signal model for a three-phase inverter connected to a microgrid 

      Alfaro Aragón, Carlos Arturo; Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Miret Tomàs, Jaume; Castilla Fernández, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2022-07-21)
      Article
      Accés obert
      Small-signal models are the mostly used to model and design in inverter-dominated microgrids. Conversely, this paper proposes a large-signal model for grid-forming inverters connected to a microgrid based on the active and ...
