  • Partitioning approach for large wind farms: active power control for optimizing power reserve 

    Siniscalchi Minna, Sara; Ocampo-Martínez, Carlos; Bianchi, Fernando Daniel; Prada Gil, Mikel de; De Schutter, Bart (IEEE Press, 2018)
    Text en actes de congrés
    Accés obert
    Nowadays, large wind farms are expected to guarantee stability of the electrical grid contributing with ancillary services, such as frequency support. To this end, wind farm controllers must set the power generation of ...

  • SMAP multi-temporal vegetation optical depth retrieval as an indicator of crop yield trend and crop composition 

    Chaparro Danon, David; Vall-Llossera Ferran, Mercedes Magdalena; Camps Carmona, Adriano José; Piles de la Fuente, María Pilar; Konings, Alexandra G.; Entekhabi, Dara (Institute of Electrical and Electronics Engineers (IEEE), 2017)
