    • Modeling the hidden flexibility of clustered unit commitment 

      Morales España, German Andres; Tejada Arango, Diego Alejandro (2019-07-01)
      This letter proposes a clustered unit commitment (CUC) formulation to accurately model flexibility requirements such as ramping, reserves, and startupshutdown constraints. The classic CUC intrinsically and hiddenly ...

    • PEV storage in multi-bus scheduling problems 

      Momber, Ilan; Morales España, German Andres; Ramos Galán, Andrés; Gómez San Román, Tomás (Association des Economistes de l'Energie (París, Francia), 04/06/2015)
      Modeling electricity storage to address challenges and opportunities of its applications for smart grids requires inter-temporal equalities to keep track of energy content over time. Prevalently, these constraints present ...

    • Power-based generation expansion planning for flexibility requirements 

      Tejada Arango, Diego Alejandro; Morales España, German Andres; Wogrin, Sonja; Centeno Hernáez, Efraim
      Flexibility requirements are becoming more relevant in power system planning due to the integration of variable Renewable Energy Sources (vRES). In order to consider these requirements Generation Expansion Planning (GEP) ...

    • Power-capacity and ramp-capability reserves for wind integration in power-based UC 

      Morales España, German Andres; Baldick, Ross; García González, Javier; Ramos Galán, Andrés (2016-04-01)
      This paper proposes a power-based network-constrained unit commitment (UC) model as an alternative to the traditional deterministic UCs to deal with wind generation uncertainty. The formulation draws a clear distinction ...

    • Reconocimiento de comandos por voz con máquinas de soporte vectorial a través de bandas espectrales 

      Morales España, German Andres; Barrera Cárdenas, Rene; Mora Flórez, Juan (01/12/2007)
      Available: http://www.utp.edu.co/php/revistas/ScientiaEtTechnica/docsFTP/17222079-84.pdf - En este artículo se propone una metodología para reconocimiento de comandos hablados, utilizando Máquinas de Soporte Vectorial ...

    • Tight and compact MILP formulation for the thermal unit commitment problem 

      Morales España, German Andres; Latorre Canteli, Jesús María; Ramos Galán, Andrés (Association des Economistes de l'Energie (París, Francia), 04/06/2015)
      This paper presents a Mixed-Integer Linear Programming (MILP) reformulation of the thermal Unit Commitment (UC) problem. The proposed formulation is simultaneously tight and compact. The tighter characteristic reduces the ...

    • Tight and compact MILP formulation of start-up and shut-down ramping in unit commitment 

      Morales España, German Andres; Latorre Canteli, Jesús María; Ramos Galán, Andrés (Sin editorial (Vancouver, Canadá), 21/07/2013)
      This paper presents a Mixed-Integer Linear Programming (MILP) formulation of Start-Up (SU) & Shut-Down (SD) power trajectories of thermal units. Multiple SU powertrajectories and costs are modeled according to how long the ...

    • Tight and compact MIP formulation of configuration-based combined-cycle units 

      Morales España, German Andres; Correa-Posada, Carlos M.; Ramos Galán, Andrés (2016-03-01)
      Private investors, flexibility, efficiency and environmental requirements from deregulated markets have led the existence and building of a significant number of combined-cycle gas turbines (CCGTs) in many power systems. ...

    • Tight MIP formulations of the power-based unit commitment problem 

      Morales España, German Andres; Gentile, C.; Ramos Galán, Andrés (2015-10-01)
      This paper provides the convex hull description for the basic operation of slow- and quick-start units in power-based unit commitment (UC) problems. The basic operating constraints that are modeled for both types of units ...
