The role of energy storage and cross-border interconnections for increasing the flexibility of future power systems : the case of Colombia
(2021-04-20)
The rapid expansion of renewable energy technologies in the electricity sector
introduces new significant challenges for power systems due to their high
intermittency. Therefore, more flexibility is needed to ensure that ...
Network resource mobilisation limitations and the alliance portfolio network
(2021-03-11)
Purpose –The purpose of this study is to examine how access and mobilisation of network resources influence a firm’s performance. It has been established that alliance portfolio (AP) network parameters shape the access to ...

Phakopsora pachyrhizi is the major pathogen associated with soybean rust in Colombia
(2021-03-26)
Soybean crops grown in the plains of eastern Colombia have been affected by the incidence of rust. This disease, still officially regarded as American soybean rust (caused by Phakopsora meibomiae) by the Colombian Department ...
A model for the development of programming courses to promote the participation of young women in STEM
(2021-10-26)
There is a gender gap in science, technology, engineering, and mathematics (STEM), and this is a global problem that affects society. However, it is worth pointing out that the gap is not uniform in all STEM fields. Women’s ...
A preliminary analysis for selecting the best hydrological probability density functions of annual peak flows associated to various return periods in some rivers of Colombia
(2021-11-01)
Analysis of extreme events of annual flow peaks are used for sizing hydraulic structures for specified return period. Cumulative distribution functions are applied to annual flow peak records in order to obtain extreme ...
A predictive model for the missing people problem
(2021-03-01)
The disappearance of people is a multidimensional phenomenon, in which several aspects must be considered. It affects people’s security perception and consumes police resources in its treatment. Therefore, does exists an ...
An IDA-PBC Design with Integral Action for Output Voltage Regulation in an Interleaved Boost Converter for DC Microgrid Applications
(2021-12-29)
This paper describes the output voltage regulation control for an interleaved connected
to a direct current (DC) microgrid considering bidirectional current flows. The proposed controller
is based on an interconnection ...
Voltage regulation of an isolated DC microgrid with a constant power load: a passivity-based control design
(2021-08-28)
Passivity-based nonlinear control for an isolated microgrid system is proposed in this paper. The microgrid consists of a photovoltaic array and a battery energy storage connected to a point of common converters, supplying ...
Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(2021-04-30)
This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...
