Heuristic Methodology for Planning AC Rural Medium-Voltage Distribution Grids
(2021-08-20)
The optimal expansion of AC medium-voltage distribution grids for rural applications is addressed in this study from a heuristic perspective. The optimal routes of a distribution feeder are selected by applying the concept ...
Cultural damage and reparation of victims in the Colombian armed conflict. The case of the black peasant community of San Cristóbal (Montes de María – Colombia)
(2021-05-16)
The aim of this study is to identify and analyze the cultural damage caused by the armed conflict in the black peasant community of San Cristóbal, in Montes de María, one of the regions most affected by the prolonged ...
Genetic-convex model for dynamic reactive power compensation in distribution networks using D-STATCOMs
(2021-04-21)
This paper proposes a new hybrid master–slave optimization approach to address the problem of the optimal placement and sizing of distribution static compensators (D-STATCOMs) in electrical distribution grids. The optimal ...
Reduction of annual operational costs in power systems through the optimal siting and sizing of STATCOMs
(2021-04-17)
The problem of the optimal siting and placement of static compensates (STATCOMs) in
power systems is addressed in this paper from an exact mathematical optimization point of view. A
mixed-integer nonlinear programming ...
Performance evaluation of structures with reinforced concrete columns retrofitted with steel jacketing
(2021-01)
Several existing reinforced concrete (RC) buildings fail to conform with current seismic codes, increasing its susceptibility to damage and collapse during earthquakes. A concern for building upgrading and rehabilitation ...
Assessing and classification of academic efficiency in engineering teaching programs
(2021-03-31)
This research uses a three-phase method to evaluate and forecast the academic efficiency of
engineering programs. In the first phase, university profiles are created through cluster analysis. In
the second phase, the ...
Hydrological considerations for sizing of a barge discharge pipeline runway
(2021-11-01)
A key element for water supply systems is the design of the water intake components. Mobile floating platforms (barges) are helpful when the hydraulic system displays substantial variations in water levels. This study ...
Study of early P91 dual corrosion in steam and simulated combustion gases from a gas-fired boile
(2021-07-25)
P91 ferritic steel pipes face dual environments during boilers operation: steam-side and fire-side. This P91 steel assessment differs from the dual studies performed to simulate coal-fired boilers -oxyfuel/steam atmospheres- ...
Application of the vortex search algorithm to the phase-balancing problem in distribution systems
(2021-02-26)
This article discusses the problem of minimizing power loss in unbalanced distribution systems through phase-balancing. This problem is represented by a mixed-integer nonlinear-programming mathematical model, which is ...
Reduction of losses and operating costs in distribution networks using a genetic algorithm and mathematical optimization
(2021-02-09)
This study deals with the minimization of the operational and investment cost in the distribution and operation of the power flow considering the installation of fixed-step capacitor banks. This issue is represented by a ...
