      Conference report
      Open Access
      1. Introduction Hydrogen is a convenient way of storing the intermittent nature of renewable energy surplus generation in such a way that it can be released at a later place or time in a controlled manner, which is the ...
    • Robust power converters for renewable generation systems in future networks with short circuit ratio wide variations 

      Santamaria Martin, G.; Griñó Cubero, Robert; Gil De Muro, Asier (2024-07-29)
      Article
      Open Access
      The European Directive (EU) 2018/2001 requests the connection of a new renewable inverter-based resources (RIR) but ensuring that the connection point is strong enough to minimize and avoid possible interaction phenomena. ...
    • Improving voltage support in islanded AC microgrids during unbalanced short-circuit faults 

      Castilla Fernández, Miguel; Miret Tomàs, Jaume; Borrell Sanz, Ángel; Duarte Mejía, Josué Neftali; Camacho Santiago, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2024-12-03)
      Article
      Restricted access - publisher's policy
      In the event of a short-circuit fault in an islanded ac microgrid, grid-forming power inverters activate a resistive virtual impedance to protect themselves against over-current, whereas grid-feeding power inverters are ...
    • Distributed generator with virtual grid-based remote voltage unbalance compensation and maximum current limiting 

      Iñiguez Amigot, José Ignacio; Miret Tomàs, Jaume; Camacho Santiago, Antonio; Castilla Fernández, Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2024)
      Conference report
      Restricted access - publisher's policy
      This paper proposes a control scheme for a distributed generator to eliminate the negative-sequence voltage at a remote point of the power system based on the virtual grid concept. The proposed control includes an additional ...
    • Fault prognosis approach using data-driven structurally generated residuals 

      Fang, Xin; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2024)
      Conference report
      Restricted access - publisher's policy
      This paper presents a fault prognosis approach using data-driven structurally generated residuals. It assumes that a set of residuals generated using structural analysis (SA) and identified using data-driven approach are ...
    • A game-theoretical control framework for transactive energy trading in energy communities 

      Mignoni, Nicola; Martínez Piazuelo, Juan Pablo; Carli, Raffaele; Ocampo-Martínez, Carlos; Quijano Silva, Nicanor; Dotoli, Mariagrazia (Institute of Electrical and Electronics Engineers (IEEE), 2024)
      Conference report
      Restricted access - publisher's policy
      Under the umbrella of non-cooperative game theory, we formulate a transactive energy framework to model and control energy communities comprised of heterogeneous agents including (yet not limited to) prosumers, energy ...
    • Fault diagnosis using interval data-driven LPV observers and structural analysis 

      Fang, Xin; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2024)
      Article
      Open Access
      This paper presents a Fault Detection and Isolation (FDI) method that combines Structural Analysis (SA) and machine learning data-driven techniques. The adaptive network fuzzy inference system (ANFIS) is used to obtain a ...
    • Roboticists' perspective on social robots in social institutions: how to design social robots that can operate in complex social environments? 

      Clodic, Aurélie; HAKLI, Raul; Repiso Polo, Ely; BELHASSEIN, Kathleen (IOS Press, 2023)
      Part of book or chapter of book
      Restricted access - publisher's policy
      In order to operate successfully in human social world, robots need to collect and represent information not only about the physical environment, but the other agents and their beliefs and goals, groups of agents with ...
    • Towards a system that allows robots to use commitments in joint action with humans 

      Repiso Polo, Ely; Sarthou, Guillaume; Clodic, Aurélie (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Conference report
      Restricted access - publisher's policy
      In collaborative tasks, expectations for achieving shared goals arise at all hierarchical plan levels, including plans, tasks, subtasks, and actions. However, these expectations also generate uncertainties for individuals ...
    • Análisis no supervisado de registros de salud de COVID-19 mediante grafos y aprendizaje profundo
