    Flexibility and reliability of AC microgrids are enhanced by reducing the dependence on communications in multi-layer hierarchical control. In this sense, this paper presents a secondary control with no communications for ...
  • Els sistemes encastats: impacte i reptes de futur 

    Verdaguer-Codina, Joan; Rubiés, José Luis; Badia, David; Pi, Xavier; Frigola Bourlon, Manel (Institut d'Estudis Catalans (IEC), 2017)
    Article
    Open Access
    S’analitza l’impacte que tenen els moderns sistemes electrònics encastats en diferents àmbits, com són la societat, l’àmbit industrial i l’educació. Es presenta una breu definició del que és un sistema encastat i es donen ...
  • Performance evaluation of secondary control policies with respect to digital communications properties in inverter-based islanded microgrids 

    Martí Colom, Pau; Velasco García, Manel; Martín Rull, Enric Xavier; García de Vicuña Muñoz de la Nava, José Luis; Miret Tomàs, Jaume; Castilla Fernández, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-12)
    Article
    Open Access
    A key challenge for inverted-based microgrids working in islanded mode is to maintain their own frequency and voltage to a certain reference values while regulating the active and reactive power among distributed generators ...
  • On gait analysis estimation errors using force sensors on a smart rollator 

    Ballesteros, Joaquin; Urdiales García, Cristina; Martínez Velasco, Antonio Benito; Dieën, Jaap H. van (2016-11-01)
    Article
    Open Access
    Gait analysis can provide valuable information on a person’s condition and rehabilitation progress. Gait is typically captured using external equipment and/or wearable sensors. These tests are largely constrained to specific ...
