    Article
    Restricted access - publisher's policy
    We present in this paper lightning current measurements, LMA (Lightning Mapping Array) data and fast antenna electric fields associated with upward flashes observed at the Säntis Tower during summer of 2017. The LMA network ...
  • Synchronous frequency support of photovoltaic power plants with inertia emulation 

    Verdugo Retamal, Cristian Andrés; Tarraso Martínez, Andrés; Candela García, José Ignacio; Rocabert Delgado, Joan; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Grid stability is one of the main concerns in renewable energies. The lack of inertia and their low capability to provide frequency support has created the need for implementing new control strategies to solve this problem. ...
  • Measurement-based network clustering for active distribution systems 

    Monadi, Mehdi; Hooshyar, Hossein; Vanfretti, Luigi; Mahmood, Farhan; Candela García, José Ignacio; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019-04-11)
    Article
    Open Access
    This paper presents a network clustering (NC) method for active distribution networks (ADNs). Following the outage of a section of an ADN, the method identifies and forms an optimum cluster of microgrids within the section. ...
  • Experimental study of visual corona under aeronautic pressure conditions using low-cost imaging sensors 

    Riba Ruiz, Jordi-Roger; Gómez Pau, Álvaro; Moreno Eguilaz, Juan Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2020-01-11)
    Article
    Open Access
    Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are ...

    El 2 y 3 de noviembre del 2019 tuvo lugar en Barcelona la novena edición de la feria de la movilidad eléctrica, Expoelectric. Esta feria es una iniciativa pionera que acerca el vehículo eléctrico de cero emisiones y las ...
  • Optimal operation of isolated microgrids considering frequency constraints 

    Vidal Clos, Josep Andreu; Bullich Massagué, Eduard; Aragüés Peñalba, Mònica; Vinyals Canal, Guillem; Chillón Antón, Cristian; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol; Galceran Arellano, Samuel (Multidisciplinary Digital Publishing Institute, 2019-01-09)
    Article
    Open Access
    Isolated microgrids must be able to perform autonomous operation without external grid support. This leads to a challenge when non-dispatchable generators are installed because power imbalances can produce frequency ...
  • Recursive model identification for the analysis of the autonomic response to exercise testing in Brugada syndrome 

    Calvo González, Mireia; Le Rolle, Virginie; Romero Pérez, Daniel; Béhar, Nathalie; Gomis Román, Pedro; Mabo, Philippe; Hernández Rodríguez, Alfredo Ignacio (2019-01-01)
    Article
    Open Access
    This paper proposes the integration and analysis of a closed-loop model of the baroreflex and cardiovascular systems, focused on a time-varying estimation of the autonomic modulation of heart rate in Brugada syndrome (BS), ...
  • Power quality disturbances assessment during unintentional islanding scenarios. A contribution to voltage sag studies 

    Serrano Fontova, Alexandre; Casals Torrens, Pau; Bosch Tous, Ricardo (2019-08-20)
    Article
    Open Access
    This paper presents a novel voltage sag topology that occurs during an unintentional islanding operation (IO) within a distribution network (DN) due to large induction motors (IMs). When a fault occurs, following the circuit ...
  • Contribution of smart cities to the energy sustainability of the binomial between city and country 

    Villa Arrieta, Manuel Ricardo; Sumper, Andreas (Multidisciplinary Digital Publishing Institute, 2019-08-01)
    Article
    Open Access
    Cities are at the center of the transition to a decarbonized economy. The high consumption of electricity in these urban areas causes them to be the main focus of greenhouse gas emissions. However, they have a high margin ...
  • Gigantic jet discharges evolve stepwise through the middle atmosphere
