    • Multi-objective bi-level optimization problem for the investment in new gas infrastructures 

      Valle Díez, Aurora del; Wogrin, Sonja; Reneses Guillén, Javier
      While there is a huge uncertainty in the gas sector and its role in the future energy mix is not clear, in order to adapt to the new challenges in the energy use, to achieve the 2020, 2030 and 2050 objectives and to continue ...

    • Optimization and modeling as decision support tools in a transitioning power system 

      Wogrin, Sonja (Association des Economistes de l'Energie (París, Francia), 04/06/2015)
      In the last two decades, electric power systems have undergone drastic changes mostly due to the liberalization of the sector and the growing penetration of renewable energy sources in the generation mix. This talk presents ...

    • Optimizing storage operations in longer-term power system models 

      Wogrin, Sonja; Galbally, David; Reneses Guillén, Javier (Sin editorial (París, Francia), 04/06/2015)
      In a rapidly changing power system the proper characterization of storage behavior becomes an increasingly important issue. We propose a new formulation to capture storage behavior in medium -and long -term power system ...

    • Optimizing storage operations in transmission-constrained networks for medium-and long-term operation 

      Tejada Arango, Diego Alejandro; Wogrin, Sonja; Centeno Hernáez, Efraim (Institute for Operations Research and the Management Sciences (Nashville, Estados Unidos de América), 13/11/2016)
      The main objective is to present a new approach to model the storage operation in the context of Medium-and Long-term Operational Planning (MLTOP). This approach is based on the system-state framework but including ...

    • Optimizing storage siting, sizing and technology portfolios in transmission-constrained networks 

      Wogrin, Sonja; Gayme, Dennice F. (01/11/2015)
      In this paper we propose a DC OPF framework for storage portfolio optimization in transmission constrained power networks. In particular, this model is designed to investigate two problems: (i) optimizing storage operation ...

    • Policy implications of downscaling the time dimension in power system planning models to represent variability in renewable output 

      Reichenberg, Lina; Siddiqui, Afzal Saeed; Wogrin, Sonja (15/09/2018)
      Due to computational constraints, power system planning models are typically unable to incorporate full annual temporal resolution. In order to represent the increased variability induced by large amounts of renewables, ...

    • 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) ...

    • Renewable generation expansion under different support schemes: a stochastic equilibrium approach 

      Pineda Morente, Salvador; Boomsma, Trine Krogh; Wogrin, Sonja (01/05/2018)
      Following the deregulation of electricity markets, a current challenge of policy makers is to facilitate the transition to a sustainable power system at the highest welfare for society. In this paper we investigate the ...

    • 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 ...

    • Transmission expansion planning outside the box: a bilevel approach 

      Tejada Arango, Diego Alejandro; Wogrin, Sonja; Pineda Morente, Salvador; González Romero, Isaac Camilo (Springer (Cham, Suiza), 20/11/2020)
      Desde el inicio del proceso de liberalización del sector energético y la llegada de los mercados eléctricos, la toma de decisiones se ha alejado de los planificadores centralizados y ha pasado a ser responsabilidad de ...

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

      Sánchez Martín, Pedro; Tejada Arango, Diego Alejandro; Wogrin, Sonja; Ramos Galán, Andrés
