  • Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability 

    Aguilar Galván, Daniel; Rolán Blanco, Alejandro; Vázquez, Gerardo; Córcoles López, Felipe; Rodríguez Cortés, Pedro (2009)
    Conference lecture
    Open Access
    This paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ...

  • Influence of the ICFF decoupling technique on the stability of the current control loop of a grid-tied VSC 

    Marín Arévalo, Leonardo Vidal; Tarraso Martínez, Andrés; Candela García, José Ignacio; Rye, Rebecca; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    The control scheme of grid-tied converters is often implemented in the dq-frame due to simplicity of design. However, with this transformation, there exists an inherent cross-coupling term between the d-and q-channels which ...

  • Synchronous power controller for distributed generation units 

    Tarraso Martínez, Andrés; Verdugo Retamal, Cristian Andrés; Lai, Ngoc-Bao; Candela García, José Ignacio; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Renewable energies has shown to be a promising solution to improve the energy injected to the electrical network. However, the lack of inertia in such systems have proven to affect the grid stability, as those technologies ...

  • LMI-based control design to enhance robustness of synchronous power controller 

    Lai, Ngoc-Bao; Tarraso Martínez, Andrés; Rodríguez Cortés, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019)
