    • A distributed control for accurate active-power sharing in islanded microgrids subject to clock drifts 

      Alfaro Aragón, Carlos Arturo; Castilla Fernández, Miguel; Camacho Santiago, Antonio; Martí Colom, Pau; Velasco García, Manel (2021-01-28)
      Article
      Open Access
      Inverters-based islanded microgrids are operated by local digital signal processors, driven by their own local clocks. These local clocks have drifts affecting the clock signals which are used to control the inverters 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
      Open Access
      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 ...
    • Corrección de los efectos de las derivas de reloj en microrredes de alterna con inversores de potencia trifásicos 

      Alfaro Aragón, Carlos Arturo (Universitat Politècnica de Catalunya, 2018-02)
      Master thesis
      Open Access
      En las microrredes que trabajan con inversores sus controles son operados generalmente por microcontroladores locales, los cuales tienen sus propios relojes que difieren entre cada uno en la medición del tiempo. Los ...
    • 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
      Open Access
      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 ...
    • Distributed direct power sliding-mode control for islanded AC microgrids 

      Alfaro Aragón, Carlos Arturo; Guzmán Solà, Ramon; García de Vicuña Muñoz de la Nava, José Luis; Komurcugil, Hasan; Martín Cañadas, María Elena (Institute of Electrical and Electronics Engineers (IEEE), 2022-10)
      Article
      Open Access
      The aim of this paper is to develop a novel distributed direct power sliding-mode control for an islanded AC microgrid. This solution replaces the droop mechanism of each inverter with two separate sliding surfaces working ...
    • Dual-loop continuous control set model predictive control for a three-phase unity power factor rectifier 

      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), 2021-08-24)
      Article
      Open Access
      In this paper, a novel cascade model predictive control for a three-phase unity power factor rectifier is presented. Unlike the traditional control techniques for rectifiers, the proposed method uses a cascade dual-model ...
    • Improving voltage imbalance in inverter-based islanded microgrids during line-to-line short circuits 

      Castilla Fernández, Miguel; Miret Tomàs, Jaume; García de Vicuña Muñoz de la Nava, José Luis; Borrell Sanz, Ángel; Alfaro Aragón, Carlos Arturo (2023-08-19)
      Article
      Open Access
      Line-to-line short circuits are the transient disturbances that cause the highest currents as well as the largest voltage imbalances in inverter-based microgrids. This paper presents a control scheme for grid-forming ...
    • Una nueva perspectiva del modelado y control de microrredes eléctricas y convertidores de potencia 

      Alfaro Aragón, Carlos Arturo (Universitat Politècnica de Catalunya, 2022-06-28)
      Doctoral thesis
      Open Access
      (English) This doctoral thesis focuses on the modeling and control of electrical microgrids and triphasic converters. The starting points of this research work are based on previous work on modeling electrical microgrids ...
