A decentralized solution for transmission expansion planning: getting inspiration from nature
Lumbreras Sancho, Sara; Wogrin, Sonja; Navarro Llevat, Guillermo; Bertazzi, Ilaria; Pereda García, Maria (2019-12-01)Transmission expansion planning is a problem of considerable complexity where classical optimization techniques are unable to handle large case studies. Decomposition and divide-and-conquer strategies have been applied to ... -
A fundamental analysis on the implementation and development of virtual natural gas hubs
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 ... -
A review of energy storage system legislation in the US and the European Union
Tejada Arango, Diego Alejandro; Siddiqui, Afzal Saeed; Wogrin, Sonja; Centeno Hernáez, Efraim (2019-03-15)Purpose of Review: This paper focuses on the current possibilities for energy storage systems (ESS) to participate in different power system services. ESS can provide multiple services such as spinning reserve, deferral ... -
Addressing flexibility issues in clustered unit commitment formulations for generation expansion planning models
Tejada Arango, Diego Alejandro; Morales España, German Andres; Wogrin, Sonja; Centeno Hernáez, EfraimThis work proposes a Clustered Unit Commitment (CUC) formulation to accurately model flexibility requirements such as ramping, reserve, and startupshutdown constraints. The classic CUC intrinsically and hiddenly overestimates ... -
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, EfraimAs 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 ... -
Analyzing time period aggregation methods for power system investment and operation models with renewables and storage
Wogrin, Sonja; Tejada Arango, Diego Alejandro; Pineda Morente, Salvador; Morales González, Juan MiguelThe transition of the power system from its current state to the power system of the future is heavily influenced by the growing penetration of renewables combined with the increasing importance of storage technologies. ... -
