(Facultad de Ingeniería, 2015)
On the Efficiency in Electrical Networks with AC and DC Operation Technologies: A Comparative Study at the Distribution Stage
(MDPI, 2020-09-20)
This research deals with the efficiency comparison between AC and DC distribution networks that can provide electricity to rural and urban areas from the point of view of grid energy losses and greenhouse gas emissions ...
A STEADY-STATE APPROACH TO PREVENT VOLTAGE COLLAPSE IN POWER SYSTEM
(Universidad de Costa Rica, 2013)
A Hybrid Methodology for a Contigency Constrained Economic Dispatch under High Variability in the Renewable Generation
(Institute of Electrical and Electronics Engineers, 2019-12)
The increasing use of distributed energy resources in power grids has renewed the interest in economic dispatch problems. In this context, a challenging problem consists in minimizing the effects of contingencies due to ...
Optimal sizing method of vanadium redox flow battery to provide load frequency control in power systems with intermittent renewable generation
(Institution of Engineering and Technology, 2017-12)
This study proposes a novel methodology for optimal sizing of a vanadium redox flow battery (VRFB) aiming at providing the load frequency control (LFC) of power system (PSs) with renewable generation, such as wind generation. ...
On the optimal selection and integration of batteries in dc grids through a mixed-integer quadratic convex formulation
(MDPI, 2021-10)
This paper deals with the problem of the optimal selection and location of batteries in DC distribution grids by proposing a new mixed-integer convex model. The exact mixed-integer nonlin-ear model is transformed into a ...
