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 ... -
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. ... -
Enhanced representative days and system states modeling for energy storage investment
Tejada Arango, Diego Alejandro; Wogrin, Sonja; Centeno Hernáez, Efraim -
Explaining the solutions of the unit commitment with interpretable machine learning
Lumbreras Sancho, Sara; Tejada Arango, Diego Alejandro; Elechiguerra Batlle, DanielThe energy transition needs mathematical models to address the complexity of shifting towards sustainable energy sources. In addition to providing accurate solutions, these models must be explainable and available for ... -
Gestión energética en sistemas eléctricos
Díaz Duran, Cristian; Tejada Arango, Diego Alejandro; Ramos Galán, Andrés; Latorre Canteli, Jesús MaríaUna correcta gestión energética de los sistemas eléctricos está directamente relacionada con una correcta planeación de los recursos, procurando garantizar la confiabilidad en el suministro. De ahí, la planeación debe ... -
On the proper use of net present value for capacity expansion planning with renewable generation
Centeno Hernáez, Efraim; Wogrin, Sonja; Tejada Arango, Diego AlejandroGeneration investment costs are significantly decreasing for some renewable technologies as wind or solar power, making them an attractive option for generation capacity expansion. Nevertheless, most of the available ... -
Optimizing storage allocation and investment for transmission constrained networks considering losses and high renewable penetration
Wogrin, Sonja; Tejada Arango, Diego Alejandro; Yacar, DeanThis work investigates the effects of transmission losses, constraints and increased renewable energy penetration on planning energy storage allocation and investment. By modifying a DC Optimal Power Flow model using a ... -
Optimizing storage operations in transmission-constrained networks for medium-and long-term operation
Tejada Arango, Diego Alejandro; Wogrin, Sonja; Centeno Hernáez, EfraimThe 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 ... -
Show me the money! Energy storage systems between the technically feasible and the economically viable
Wogrin, Sonja; Tejada Arango, Diego AlejandroDue to the recommendations of the IPCC Global Warming report [ 1 ], CO2 emissions have to be halved by 2030 in order to avoid devastating changes to our climate. The 2030 climate and energy framework [ 2 ] that was adopted ... -
Show me the money! Profitability of energy storage systems in low-carbon power systems
Wogrin, Sonja; Tejada Arango, Diego Alejandro; Delikaraoglou, Stefanos; Botterud, AudunEnergy storage systems are bound to play a critical role in the transition towards a decarbonized power sector with high shares of variable renewables. However, an open question is whether all storage capacity that is ... -
Two-stage recombinatory benders decomposition
Díaz Duran, Cristian; Correa-Posada, Carlos M.; Ramos Galán, Andrés; Latorre Canteli, Jesús María; Tejada Arango, Diego AlejandroThe main goal of the power systems planning is the optimal management of the energy resources in order to ensure a safe and reliable operation. Otherwise, the system operation and reliability will be compromised, as happened ... -
Unit commitment with ACOPF constraints: practical experience with solution techniques
Tejada Arango, Diego Alejandro; Wogrin, Sonja; Sánchez Martín, Pedro; Ramos Galán, AndrésThis paper summarizes practical experiences of solving the UC problem with AC optimal power flow constraints using three main approaches: 1) solving a MINLP with commercial solvers, 2) an outer approximation approach with ... -
What time-period aggregation method works best for power system operation models with renewablesand storage?
Wogrin, Sonja; Tejada Arango, Diego Alejandro; Pineda Morente, Salvador; Morales González, Juan MiguelIn this paper we compare two cutting-edge timeperiod aggregation methodologies for power system models that consider both renewables and storage technologies: the chronological time-period clustering; and, the enhanced ...
