Optimal Location and Sizing of DGs in DC Networks Using a Hybrid Methodology Based on the PPBIL Algorithm and the VSA
(2021-08-11)
In this paper, we propose a master–slave methodology to address the problem of optimal integration (location and sizing) of Distributed Generators (DGs) in Direct Current (DC) networks. This proposed methodology employs a ...
A sustainability maturity model for micro, small and medium-sized enterprises (MSMEs) based on a data analytics evaluation approach
(2021-05-28)
A maturity model for micro, small and medium enterprises (MSMEs) is introduced to assess the level of
implementation of sustainability strategies and practices in this type of business. According to the literature, only
a ...

Optimal integration of photovoltaic sources in distribution networks for daily energy losses minimization using the vortex search algorithm
(2021-04-20)
This paper deals with the optimal siting and sizing problem of photovoltaic (PV) generators in electrical distribution networks considering daily load and generation profiles. It proposes the discrete-continuous version ...
The equivalence between successive approximations and matricial load flow formulations
(2021-03-24)
This paper shows the equivalence of the matricial form of the classical backward/forward load flow formulation for distribution networks with the recently developed successive approximations (SA) load flow approach. Both ...

(2021-12-13)
El Encuentro Matemático del Caribe tiene como finalidad reflexionar sobre el quehacer matemático y la enseñanza de las Matemáticas en el Caribe colombiano. Así mismo, extender las redes académicas con investigadores ...
Would you Value a few More Hours of work? Underemployment and Subjective Well-Being Across Chilean Workers
(2021-04-08)
Underemployment has gained attention in recent years because of its effects on health and well-being (life satisfaction), it is a widespread phenomenon in the labor force that affects not only workers, but also households, ...
Global Optimal Stabilization of MT-HVDC Systems: Inverse Optimal Control Approach
(2021-11-17)
The stabilization problem of multi-terminal high-voltage direct current (MT-HVDC) systems feeding constant power loads is addressed in this paper using an inverse optimal control (IOC). A hierarchical control structure ...
An improved crow search algorithm applied to the phase swapping problem in asymmetric distribution systems
(2021-07-23)
This paper discusses the power loss minimization problem in asymmetric distribution
systems (ADS) based on phase swapping. This problem is presented using a mixed-integer nonlinear programming model, which is resolved by ...
Operating cost reduction in distribution networks based on the optimal phase-swapping including the costs of the working groups and energy losses
(2021-07-27)
The problem of optimal phase-balancing in three-phase asymmetric distribution networks is addressed in this research from the point of view of combinatorial optimization using a master– slave optimization approach. The ...
