    • Voltage quality improvement of microgrids under islanding mode 

      Azevedo, Gustavo; Rodríguez Cortés, Pedro; Rocabert Delgado, Joan; Calvancanti, M; Neves, F (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
      Text en actes de congrés
      Accés obert
      This paper proposes a control strategy to reduce the voltage unbalance in microgrids. The voltage unbalance compensation is achieved by injection of a proper negativesequence current into the microgrid. This task can ...
    • Voltage regulation with power curtailment in a single-phase grid-connected PV inverter 

      Biel Solé, Domingo; Scherpen, Jacquelien M. A (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work presents the design guidelines of a control for direct regulation of the voltage amplitude at the connection point of a single-phase grid-connected PV inverter. The parameters of the control are designed for ...
    • Voltage sag mitigation in a PV-based industrial microgrid during grid faults 

      Ghahderijani, Mohammad Moradi; Castilla Fernández, Miguel; García de Vicuña Muñoz de la Nava, José Luis; Camacho Santiago, Antonio; Torres Martínez, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The growing interests in industrial microgrid and its high power rating, have made it as a good candidate for voltage support purposes. The aim of this paper is to present a reactive current injection control strategy for ...
    • Voltage support control strategies for static synchronous compensators under unbalanced voltage sags 

      Castilla Fernández, Miguel; Miret Tomàs, Jaume; Camacho Santiago, Antonio; Matas Alcalá, José; García de Vicuña Muñoz de la Nava, José Luis (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Article
      Accés restringit per política de l'editorial
      Static synchronous compensators have been broadly employed for the provision of electrical ac network services, which include voltage regulation, network balance, and stability improvement. Several studies of such ...
    • Voltage support using electric vehicles in an islanded resistive-microgrid under voltage sags 

      Miret Tomàs, Jaume; Castilla Fernández, Miguel; Borrell Sanz, Àngel (2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The number of electric vehicles connected to the grid is growing constantly due to environmental and regulatory issues. Conventionally these vehicles work as variable loads, although using them as distributed generators ...
    • Voltage-sensor-less synchronization to unbalanced grids by frequency-adaptive virtual flux estimation 

      Suul, Jon Are; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Undeland, Tore (IEEE Press. Institute of Electrical and Electronics Engineers, 2012-07)
      Article
      Accés restringit per política de l'editorial
      This paper proposes a simple method for inherently frequency-adaptive virtual flux (VF) estimation intended for voltage-sensor-less grid synchronization and control of voltage source converters. The frequency-adaptive ...
