    • Enhanced representative days and system states modeling for energy storage investment 

      Tejada Arango, Diego Alejandro; Domeshek, Maya; Wogrin, Sonja; Centeno Hernáez, Efraim
      The variability of renewable energy sources and the chronological dependency of energy storage makes it necessary to incorporate short-term dynamics in renewable energy availability and de-mand into medium and long-term ...

    • 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) ...

    • Short-term storage signals in hydrothermal dispatch models using a linked representative periods approach 

      Tejada Arango, Diego Alejandro; Wogrin, Sonja; Siddiqui, Afzal Saeed; Centeno Hernáez, Efraim
      Short-term energy storage systems (STESS), e.g., batteries, are becoming one promising option to deal with flexibility require-ments in power systems due to the accommodation of renewable energy sources. Previous work using ...

    • Unit Commitment with ACOPF Constraints: Practical Experience with Solution Techniques 

      Sánchez Martín, Pedro; Tejada Arango, Diego Alejandro; Wogrin, Sonja; Ramos Galán, Andrés
      El artículo describe experiencias prácticas de resolución de problemas de asignación de grupos de generación eléctrica que incluyen restricciones que modelan la red de transporte en su formulación de corriente alterna. Se ...

    • Which unit commitment formulation is best? A comparison framework 

      Tejada Arango, Diego Alejandro; Lumbreras Sancho, Sara; Sánchez Martín, Pedro; Ramos Galán, Andrés
      The Unit Commitment (UC) problem, which deter-mines the day-ahead dispatch of generation units, is one of the key problems in power systems operation. A long list of formulations that claim to solve this problem more ...
