  • 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)
    Conference report
    Open Access
    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 ...

  • A multi-objective predictive control strategy for enhancing primary frequency support with wind farms 

    Siniscalchi Minna, Sara; Prada Gil, Mikel de; Bianchi, Fernando Daniel; Ocampo-Martínez, Carlos; De Schutter, Bart (2018)
    Conference report
    Restricted access - publisher's policy
    Nowadays, wind power plants (WPPs) should be able to dynamically change their power output to meet the power demanded by the transmission system operators. When the wind power generation exceeds the power demand, the WPP ...

  • Configurations of model predictive control to exploit energy flexibility in building thermal loads 

    Péan, Thibaut; Salom Tormo, Jaume; Costa Castelló, Ramon (IEEE Press, 2018)
    Conference report
    Open Access
