Optimization approaches in electric machine design: insights from a bibliometri...
Nascimento, Cecilia Pagnozzi do; Silvério, Ana Cristina; Baptista, Bruno; Carvalho, José Augusto; Bazzo, Thiago; Ferreira, Ângela P.Optimizing the design of electric machines is a complex task due to the large number of interrelated geometric and physical parameters that influence performance, efficiency, cost, and sustainability. Numerous deterministic and stochastic optimization techniques have been developed to address these challenges, each presenting distinct advantages and limitations. Deterministic approaches, though computationally ...
Assessing the sustainable performance of the transport sector in European count...
Gruetzmacher, Sarah; Vaz, Clara B.; Ferreira, Ângela P.The energy policy of the European Union stresses the need for sustainable energy consumption, improvements in energy efficiency and lower fossil fuel dependence in a decoupling strategy from unstable democracies. Transportation still represents a sector largely dependent on fossil fuels, which come with several negative impacts. Measuring and assessing the sustainability of the transport sector becomes necessar...
Computer Modeling for High-RES Systems: Exploring the Applicability of EnergyPLAN
Roma, Gabriel Fonseca Oliveira; Dranka, Géremi Gilson; Ferreira, Ângela P.The global energy landscape is evolving, with distributed generation (DG) playing a key role. This study assesses the applicability of EnergyPLAN, a simulation tool, for a high renewable energy source (RES) system, focusing on Brazil. By comparing EnergyPLAN outputs with data from the Brazilian National System Operator (ONS), the research evaluates its accuracy. Findings show high accuracy in annual and monthly...
Fault Classification of Wind Turbine: A Comparison of Hyperparameter Optimizati...
Pinna, Danielle; Toso, Rodrigo; Semaan, Gustavo; Sá, Fernando de; Pereira, Ana I.; Ferreira, Ângela P.; Soares, Jorge; Brandão, DiegoThe last few years have been marked by the insertion of renewable technologies in the global energy matrix, such as wind and solar energy, which are considered clean energies with low environmental impact. Wind turbines, responsible for the energy conversion process, are complex equipment that are expensive and susceptible to numerous failures. Monitoring turbine components can help detect failures before they ...
Multi-objective optimal sizing of an AC/DC grid connected microgrid system
Amoura, Yahia; Pedroso, André; Ferreira, Ângela P.; Lima, José; Torres, Santiago; Pereira, Ana I.Considering the rising energy needs and the depletion of conventional energy sources, microgrid systems combining wind energy and solar photovoltaic power with diesel generators are promising and considered economically viable for usage. To evaluate system cost and dependability, optimizing the size of microgrid system elements, including energy storage systems connected with the principal network, is crucial. ...
Development of a Simulation Tool for Electromagnetism Education
Auwarter, Bianca; Brandão, Diego; Ferreira, Ângela P.The widespread adoption in the educational system of information and communications technologies allows the use of interactive simulations, able to support a meaningful insight into the fundamental laws and concepts of electromagnetic theory, which, in a classical approach, would require a vector calculus background and three-dimensional geometrical resourcefulness, typically not maturated by the students in un...

CO2 emissions curtailment from the usage of electric vehicles in sal Island
Graça, Randi Cleiton Cardoso Brito da; Ferreira, Ângela P.Electrification of the transport sector in Cape Verde, followed by the construction of a charging infrastructure mainly supported by renewable energy, is one of the most important long-term objectives in Cape Verde. Despite having lower greenhouse gas (GHG) emissions when compared with other countries, the country adopted a strategy to decrease the consumption of fossil fuels and consequentially decrease GHG em...
A DEA approach to evaluate the performance of the electric mobility deployment ...
Vaz, Clara B.; Ferreira, Ângela P.This work aims to assess the performance of European countries on the deployment of low-emission vehicles in road transportation. For this purpose, a model based on Data Envelopment Analysis (DEA) is used to calculate a composite indicator for several European countries, aggregating seven sub-indicators built from a data set for the 2019 year. Various virtual weight restrictions schemes of the sub-indicators ar...
An innovative optimization approach for energy management of a microgrid system
Amoura, Yahia; Pereira, Ana I.; Lima, José; Ferreira, Ângela P.; Boukli-Hacene, Fouad; Torres, SantiagoThe local association of electrical generator including renewable energies and storage technologies approximately installed to the client made way for a small-scale power grid called a microgrid. In certain cases, the random nature of renewable energy sources, combined with the variable pattern of demand, results in issues concerning the sustainability and reliability of the microgrid system. Furthermore, the c...
