Study of the sustainability of electrical power systems: analysis of the causes that generate reactive power
(MDPI AG, 2019-12-16)[Abstract] Reactive power is an important parameter in electrical power systems since it affects the efficiency of the system because it is not useful energy. It decreases the power factor of the system and limits the ... -
Framework for Development of an Economic Analysis Tool for Floating Concrete Offshore Wind Platforms
(MDPI, 2020)[Abstract] The objective of this work is to establish a framework for the development of an economic analysis tool for floating offshore wind platforms built in concrete. The operation and usefulness of the beta version ... -
Assessment of the Materials Employed in Green Artificial Reefs for the Galician Estuaries in Terms of Circular Economy
(MDPI, 2020)[Abstract] To exploit marine resources in a sustainable way, efficient management systems must be used such as green artificial reefs (GARs). These reefs are mostly made up of renewable and organic materials. When adopting ... -
Analysis of the Real Energy Consumption of Energy Saving Lamps
(MDPI, 2020)[Abstract] Light emitting diode (LED) and compact fluorescent light (CFL) lamps are widely used because they are associated with low energy consumption and a reduced environmental impact. In the present paper, a study of ... -
Managing the oceans: Site selection of a floating offshore wind farm based on GIS spatial analysis
(Elsevier, 2020-03)[Abstract] The aim of this study is to develop a methodology for using Geographic Information Systems (GIS) spatial analysis in the development of a floating offshore wind farm. When you plan a floating offshore wind farm ... -
An Economic Analysis of An Innovative Floating Offshore Wind Platform Built with Concrete: The SATH® Platform
(MDPI, 2020-05)[Abstract] The goal of this work is to carry out an economic analysis of a novel floating offshore wind structure, of which the main material is concrete: the SATH® platform. It takes a step forward in floating marine wind ... -
Fatigue Study of the Pre-Corroded 6082-T6 Aluminum Alloy in Saline Atmosphere
(MDPI, 2020-09)[Abstract] This work studies the influence of the saline atmospheric corrosion on the fatigue strength of 6061-T6 aluminum alloy. For this purpose, this alloy was subjected to tests in a salt spray corrosion chamber at ... -
Analysis of Contracts to Build Energy Infrastructures to Optimize the OPEX
(MDPI, 2020-09-03)[Abstract] The employer (owner) of the project wants to obtain the maximum profit for the money invested and the consultant (contractor) will try to give less for that money. The regulation of their relationship is based ... -
