On the efficiency in electrical networks with ac and dc operation technologies: A comparative study at the distribution stage
(2020-08-20)
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 ...
Second-order cone approximation for voltage stability analysis in direct-current networks
(2020-09-24)
In this study, the voltage stability margin for direct current (DC) networks in the presence of constant power loads is analyzed using a proposed convex mathematical reformulation. This convex model is developed by employing ...
Predictive Analysis and Data Visualization Approach for Decision Processes in Marketing Strategies: A Case of Study
(2020-10-08)
In this paper, we perform a new strategy for recommender systems in online entertainment platforms. As a case of study, we analyzed the reading preferences based on users of Goodreads, a social network for readers, to ...
Bilinear Control for Three-Phase Microgrids: A Proportional-Integral Passivity-Based Design
(2020-07-30)
A bilinear PI control based on passivity theory for the adequate integration of distributed energy resources (DERs) in ac microgrids is presented in this paper. DERs are integrated into the grid by voltage source converters ...
Developing an indicator for material selection based on durability and environmental footprint: A Circular Economy perspective
(2020-05-19)
The Circular Economy comprises several strategies to enhance the sustainability of products. However, most of the research in this area has focused on Recycling, Recovering and final disposal. Strategies for lifespan ...
Reply to: Effectiveness of a visual noise warning system on noise levels in a surgical ICU
(Lippincott Williams and Wilkins, 2020)
Del biocentrismo a la seguridad humana: un enfoque en el marco del reconocimiento del páramo de Pisba como sujeto de derechos
(2020-01)
This paper discusses the status of mining operations vis-a-vis nature as a subject of rights to the extent that they represent a serious threat not only to the fauna and flora in the areas where mining takes place but also ...
Evaluation of semi-intensive green roofs with drainage layers made out of recycled and reused materials
(2020-05-29)
Green roof systems represent an opportunity to mitigate the effect of natural soil loss due to the development of urban infrastructure, which significantly affects natural processes such as the hydrological water cycle. ...
Direct power compensation in AC distribution networks with SCES systems via PI-PBC approach
(2020-04-23)
Here, we explore the possibility of employing proportional-integral passivity-based control (PI-PBC) to support active and reactive power in alternating current (AC) distribution networks by using a supercapacitor energy ...
Dynamic active and reactive power compensation in distribution networks with batteries: A day-ahead economic dispatch approach
(2020-06-08)
This paper focuses on the problems of optimal operation of battery energy storage systems (BESSs) in distributed networks from a nonlinear programming (NLP) point of view. This proposal contains the active and reactive ...
