Valle Díez, Aurora del; Dueñas Martínez, Pablo; Wogrin, Sonja; Reneses Guillén, Javier (2017-09-01)The ongoing gas market liberalization in Europe has brought up a new competitive environment in which shippers (i.e., companies that are responsible for conveying gas from producers to consumers) must adapt their behavior ... -
A new approach to model load levels in electric power systems with high renewable penetration
Wogrin, Sonja; Dueñas Martínez, Pablo; Delgadillo Vega, Andrés Ramiro; Reneses Guillén, Javier (2014-09-01)In medium- and long-term power system models it is a common approach to approximate the demand curve by load levels in order to make the models computationally tractable. However, in such an approach the chronological ... -

An MPEC for electricity retail alternatives of plug-in electric vehicle (PEV) aggregators
Momber, Ilan; Wogrin, Sonja; Gómez San Román, Tomás (Wroclaw University of Technology (Breslavia, Polonia), 2014-08-18)Coordinated charging schedules of plug-in electric vehicles (PEVs) by an aggregator agent may lead to increased system efficiency in allocating resources in generation, transmission and distribution. To achieve optimal ... -
Analysis of investments in generation capacity: a bilevel approach
Centeno Hernáez, Efraim; Wogrin, Sonja; López-Peña Fernández, Álvaro; Vázquez Martínez, Miguel (2011-08-01)This paper introduces a bilevel model that represents the behavior of a firm which, faced with the need to build new plants, has to choose between a number of alternative technologies. The main contribution of the model ... -
Analysis of storage and water value in power systems for policymaking on renewable energies
Tejada Arango, Diego Alejandro; Siddiqui, Afzal Saeed; Wogrin, Sonja; Centeno Hernáez, Efraim (European Association of Operational Research Society; Sociedad de Estadística e Investigación Operat (Valencia, España), 2018-07-08)As variable Renewable Energy Source (vRES) production, e.g., solar and wind, increases, additional Energy Storage (ES) capacity may be desirable in order to manage vRES intermittency. Moreover, since Battery Energy Storage ... -
Annualized versus overall investment cost in generation capacity expansion planning
Centeno Hernáez, Efraim; Wogrin, Sonja (Institute of Electrical and Electronics Engineers Power and Energy Society; Universidad Pontificia C (Madrid, España), 2021-07-29)Investment costs are significantly decreasing along the years for some electricity generation technologies (such as wind or solar), making them an attractive option for generation capacity expansion. Nevertheless, most of ... -
