DABGEO: a Reusable and Usable Global Energy Ontology for the Energy Domain
(Elsevier B.V.Ontology usability, 2020)
The heterogeneity of energy ontologies hinders the interoperability between ontology-based energymanagement applications to perform a large-scale energy management. Thus, there is the need fora global ontology that provides ...
Wind Turbine Oriented Solutions to Improve Power Quality and Harmonic Compliance of AC Offshore Wind Power Plants
(IEEE, 2021)
The operation of offshore wind power plants with respect to power quality and grid code compliance must be verified for different conditions in the design phase using harmonic analysis methods. This paper addresses this ...
Design Space Analysis of the Dual-Active-Bridge Converter for More Electric Aircraft
(MDPI, 2022)
In the literature, different DC/DC power electronic converters (PECs) have been found to interconnect high-voltage DC and low-voltage DC grids in the electric power distribution networks of aircraft. In this scenario, the ...
System of Systems Lifecycle Management: A New Concept Based on Process Engineering Methodologies
(MDPI, 2021)
In order to tackle interoperability issues of large-scale automation systems, SOA (Service-Oriented Architecture) principles, where information exchange is manifested by systems providing and consuming services, have already ...
MODDALS Methodology for Designing Layered Ontology Structures
(IOS Press, 2020)
Global ontologies include common vocabularies to provide interoperability among different applications. These ontologies require a balance of reusability-usability to minimise the ontology reuse effort in different ...
Power Capability Boundaries for an Inverter Providing Multiple Grid Support Services
(MDPI AG, 2020)
It is getting more common every day to install inverters that o er several grid support services in parallel. As these services are provided, a simultaneous need arises to know the combined limit of the inverter for those ...
Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics
(IEEE, 2022)
This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active power filter or active ...
Surface integrity evaluation within dry grinding process on automotive gears
(Elsevier B.V., 2022)
Gears are essential components in automotive transmissions and their performance directly depends on the flanks surface integrity. To date the gears whole production chain do not use lubricants, except the final step of ...
Modeling of Drag Finishing: Influence of Abrasive Media Shape
(MDPI, 2021)
Drag finishing is a widely used superfinishing technique in the industry to polish parts under the action of abrasive media combined with an active surrounding liquid. However, the understanding of this process is not ...
Li-ion Battery-based Hybrid Diesel-Electric Railway Vehicle: In-depth Life Cycle Cost Analysis
(IEEE, 2022)
In this study, the life cycle costs of railway projects involving hybrid diesel-electric vehicles are analysed. Specifically, the analysis focuses on the comparison of 3 lithium-ion battery technologies (NMC, LTO and LFP) ...
