    • Gutiérrez, Leonel; Muñoz-Carpintero, Diego; Valencia, Felipe; Sáez, Doris (Elsevier Ltd, 2018)
      Takagi–Sugeno fuzzy models are cataloged as universal approximators and have been proven to be a powerful tool for the prediction of systems. However, in certain cases they may fail to inherit the main properties of a ...
    • Barrientos, Jorge; López, José; Valencia, Felipe (MDPI AG, 2018)
      The introduction of non-conventional energy sources (NCES) to industrial processes is a viable alternative to reducing the energy consumed from the grid. However, a robust coordination of the local energy resources with ...
    • Arraño-Vargas, Felipe; Rahmann, Claudia; Valencia, Felipe; Ramírez Vargas, Luis (MDPI AG, 2017)
      © 2018 by the authors. This paper proposes an active splitting scheme especially suitable for longitudinal power systems (LPS). The proposed scheme is based on a modified out-of-step (OOS) algorithm combined with an angle ...
    • Barrientos, Jorge; López, José; Valencia, Felipe (Springer Verlag, 2018)
      Productive processes are the largest consumers in power systems. The energy required by these processes is usually supplied by the power grid with its associated high operative costs. In this work, we propose a methodology ...
    • Valencia, Felipe; Mella, José D.; González, Rafael I.; Kiwi Tichauer, Miguel; Bringa, Eduardo M. (Elsevier, 2015)
      Swift heavy ion irradiation does not generate amorphous tracks in diamond, contrary to what happens in graphite or in diamond-like carbon. Since nanocrystalline diamond is of interest for several technological applications ...
    • Espin Sarzosa, Danny Alexander; Palma Behnke, Rodrigo Ernesto Eduardo; Valencia, Felipe (IEEE-Inst Electrical Electronics Engineers, 2022)
      Small productive processes (SPPs) have recently emerged as attractive alternatives to contribute to the socio-economic development of communities, primarily in rural contexts. However, SPPs have a complicated electrical ...
    • Valencia, Felipe; González, Rafael; Vega, H.; Ruestes, Carlos; Rogan Castillo, José; Valdivia, Juan; Bringa, Eduardo; Kiwi Tichauer, Miguel (American Chemical Society, 2018)
      Palladium nanoparticles are technologically important for catalysis, hydrogen storage, and many other applications. Here, we investigate the mechanical properties of Pd hollow nanoparticles of different sizes and thicknesses ...
    • Valencia, Felipe; Sáez Hueichapán, Doris; Collado, Jorge; Avila, Fernanda; Marquez, Alejandro; Espinosa, Jairo J. (IEEE, 2016)
      Energy management systems (EMSs) are used for operators to optimize, monitor, and control the performance of a power system. In microgrids, the EMS automatically coordinates the energy sources aiming to supply the demand. ...
    • Valencia, Felipe; Palma Behnke, Rodrigo; Ortiz Villalba, Diego; Quintana, Alfredo de la; Rahmann, Claudia; Cifuentes, Richard (Institute of Electrical and Electronics Engineers Inc., 2017)
      Special protection schemes (SPSs) are an efficient alternative to increase the flexibility in the operation of power systems. The implementation of SPSs is often motivated by technical rather than economic reasons. The aim ...
    • Ramírez del Barrio, Paulina; Mendoza Araya, Patricio; Valencia, Felipe; León, Gonzalo; Cornejo Ponce, Lorena; Montedonico, Marcia; Jiménez Estévez, Guillermo (IEEE, 2017)
      The Ayllu Solar project’s main goal is to foster the sustainable development of rural/urban communities in Arica & Parinacota region, northern Chile, by means of using solar energy. This 5-year project is based on three ...
    • Palma Behnke, Rodrigo Ernesto Eduardo; Vega Herrera, Jorge; Valencia, Felipe; Núñez Mata, Óscar (IEEE-Inst Electrical Electronics Engineers, 2021)
      The increasing integration of renewable energy sources into current power systems has posed the challenge of adequately representing the statistical properties associated with their variable power generation. In this paper, ...
    • Ramírez, Max; González, Rafael I.; Baltazar, Samuel E.; Rojas-Nunez, Javier; Allende, Sebastián; Valdivia, Juan Alejandro; Rogan Castillo, José; Kiwi Tichauer, Miguel; Valencia, Felipe (Royal Society of Chemistry, 2019)
      Oxygen absorption and the thermal stability of Al147 nanoparticles were studied by means of classical molecular dynamics simulations and Monte Carlo methods. The results suggest that for the studied sizes, oxygen incorporation ...
