  • Generalized unit commitment by the radar multiplier method 

    Beltrán Royo, César (Universitat Politècnica de Catalunya, 2001-07-09)
    Doctoral thesis
    Open Access
    This operations research thesis should be situated in the field of the power generation industry. The general objective of this work is to efficiently solve the Generalized Unit Commitment (GUC) problem by means of specialized ...
  • Minimización global de un polinomio en la recta real 

    Beltrán Royo, César (Institut d'Estadística de Catalunya, 1999)
    Open Access
    En este art´ıculo presentamos y probamos num´ericamente un nuevo algoritmo para la minimizaci´on global de un polinomio de grado par. El algoritmo est´a basado en la simple idea de trasladar verticalmente el grafo ...
  • Short-term hydrothermal coordination by augmented lagrangean relaxation: a new multiplier updating 

    Beltrán Royo, César; Heredia, F.-Javier (Francisco Javier) (1999-12)
    Open Access
    The Augmented Lagrangean Relaxation (ALR) method is one of the most powerful techniques to solve the Short-Term Hydrothermal Coordination (STHC) problem. A crucial step when using the ALR method is the updating of the ...
  • Unit commitment by augmented lagrangian relaxation: testing two decomposition approaches 

    Beltrán Royo, César; Heredia, F.-Javier (Francisco Javier) (2002-02)
    Restricted access - publisher's policy
    One of the main drawbacks of the augmented Lagrangian relaxation method is that the quadratic term introduced by the augmented Lagrangian is not separable. We compare empirically and theoretically two methods designed ...
