A bilevel framework for decision-making under uncertainty with contextual information
Morales-González, Juan Miguel
; Pineda-Morente, Salvador; Muñoz Díaz, Miguel Ángel (Elsevier, 2021-11-22)
In this paper, we propose a novel approach for data-driven decision-making under uncertainty in the presence of contextual information. Given a finite collection of observations of the uncertain parameters and potential ... -
A data-based approach for solving the Rank Pricing Problem.
The Rank Pricing Problem is a challenging mixed-integer optimization problem. It aims to determine the optimal pricing strategies of a set of products ranked by customer preferences. Given its NP-hard nature, existing ... -
A high dimensional functional time series approach to evolution outlier detection for grouped smart meters
Elías Fernández, Antonio; Morales-González, Juan Miguel; Pineda-Morente, Salvador (Taylor and Francis, 2022-01-01)
Smart metering infrastructures collect data almost continuously in the form of fine-grained long time series. These massive data series often have common daily patterns that are repeated between similar days or seasons and ... -
A novel embedded min-max approach for feature selection in nonlinear Support Vector Machine classification
Jiménez-Cordero, María Asunción; Morales-González, Juan Miguel; Pineda-Morente, Salvador (Elsevier, 2021)
In recent years, feature selection has become a challenging problem in several machine learning fields, such as classification problems. Support Vector Machine (SVM) is a well-known technique applied in classification ... -
An exact dynamic programming approach to segmented isotonic regression
Bucarey, Víctor; Labbé, Martine; Morales-González, Juan Miguel; Pineda-Morente, Salvador (Elsevier, 2021)
This paper proposes a polynomial-time algorithm to construct the monotone stepwise curve that minimizes the sum of squared errors with respect to a given cloud of data points. The fitted curve is also constrained on the ... -

Chronological Time-Period Clustering for Optimal Capacity Expansion Planning
Morales-González, Juan Miguel; Pineda-Morente, Salvador (2018-07-06)
To reduce the computational burden of capacity expansion models, power system operations are commonly accounted for in these models using representative time periods of the planning horizon such as hours, days or weeks. ... -

Cost-driven screening of network constraints for the unit commitment problem
Porras, Álvaro; Pineda-Morente, Salvador; Morales-González, Juan Miguel; Jiménez-Cordero, María Asunción (The Institute of Electrical and Electronics Engineers (IEEE), 2022-03-16)
In an attempt to speed up the solution of the unit commitment (UC) problem, both machine-learning and optimization-based methods have been proposed to lighten the full UC formulation by removing as many superfluous line-flow ... -
Data-driven distributionally robust optimization with Wasserstein metric, moment conditions and robust constraints
Esteban-Pérez, Adrián; Morales-González, Juan Miguel (2018-07-12)
We consider optimization problems where the information on the uncertain parameters reduces to a finite data sample. Using the Wasserstein metric, a ball in the space of probability distributions centered at the empirical ... -
Data-Driven Screening of Network Constraints for Unit Commitment
Pineda-Morente, Salvador; Morales-González, Juan Miguel; Jiménez-Cordero, María Asunción (IEEE Xplore, 2020)
The transmission-constrained unit commitment (TC-UC) problem is one of the most relevant problems solved by independent system operators for the daily operation of power systems. Given its computational complexity, this ... -
Distributionally Robust Optimal Power Flow with Contextual Information
Esteban-Pérez, Adrián; Morales-González, Juan Miguel (Elsevier B. V., 2022-10)
In this paper, we develop a distributionally robust chance-constrained formulation of the Optimal Power Flow problem (OPF) whereby the system operator can leverage contextual information. For this purpose, we exploit an ... -
Distributionally robust stochastic programs with side information based on trimmings
Esteban-Pérez, Adrián; Morales-González, Juan Miguel (Springer, 2021-11)
We consider stochastic programs conditional on some covariate information, where the only knowledge of the possible relationship between the uncertain parameters and the covariates is reduced to a finite data sample of ... -
Electricity Cost-Sharing in Energy Communities Under Dynamic Pricing and Uncertainty
Gržanić, Mirna; Morales-González, Juan Miguel; Pineda-Morente, Salvador; Capuder, Tomislav (IEEE, 2021-02-15)
Most of the prosumers nowadays are constrained to trade only with the supplier under a flat tariff or dynamic time-of-use price signals. This paper models and discusses the cost-saving benefits of flexible prosumers as ... -
Feature-driven improvement of renewable energy forecasting and trading
Inspired from recent insights into the common ground of machine learning, optimization and decision-making, this paper proposes an easy-to-implement, but effective procedure to enhance both the quality of renewable energy ... -
