    • openAccess   Automatic under-frequency load shedding mal-operation in power systems with high wind power penetration 

      Aparicio, N.; Añó-Villalba, Salvador; Belenguer Balaguer, Enrique; Blasco-Gimenez, Ramon Elsevier (2017)
      Countries with a limited interconnection capacity suffer substantial frequency variations after large incidents so they use automatic under-frequency load shedding schemes to arrest the frequency decay. Some of these ...

    • openAccess   Daily Solar Energy Estimation for Minimizing Energy Storage Requirements in PV Power Plants 

      Beltran, Hector; Pérez, Emilio; Aparicio, N.; Rodríguez, Pedro Institute of Electrical and Electronics Engineers (IEEE) (2013)
      This paper proposes an optimized energy management strategy (EMS) for photovoltaic (PV) power plants with energy storage (ES) based on the estimation of the daily solar energy production. This EMS produces a constant-by-hours ...

    • openAccess   LCC-HVDC Connection of Offshore Wind Farms With Reduced Filter Banks 

      Blasco-Gimenez, Ramon; Aparicio, N.; Añó-Villalba, Salvador; Bernal-Pérez, S. Institute of Electrical and Electronics Engineers (IEEE) (2013)
      Despite being more efficient, line commutated converter-HVDC links for the connection of large offshore wind farms have ac-filter bank size as one of their main drawbacks. This paper shows how the HVDC rectifier filter ...

    • openAccess   Predictive Power Control for PV Plants With Energy Storage 

      Pérez, Emilio; Beltran, Hector; Aparicio, N.; Rodríguez, Pedro Institute of Electrical and Electronics Engineers (IEEE) (2013)
      This work presents a model predictive control (MPC) approach to manage in real-time the energy generated by a grid-tied photovoltaic (PV) power plant with energy storage (ES), optimizing its economic revenue. This MPC ...

    • openAccess   Synthesis of nonlinear controller for wind turbines stability when providing grid support 

      Peñarrocha-Alós, Ignacio; Dolz Algaba, Daniel; Aparicio, N.; Sanchis LLopis, Roberto John Wiley & Sons, Ltd. (2013)
      This paper presents a new nonlinear polynomial controller for wind turbines that assures stability and maximizes the energy produced while imposing a bound in the generated power derivative in normal operation (guarantees ...
