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. ...
Combined optimization and regression machine learning for solar Irradiation and...
Amoura, Yahia; Torres, Santiago; Lima, José; Pereira, Ana I.Prediction of solar irradiation and wind speed are essential for enhancing the renewable energy integration into the existing power system grids. However, the deficiencies caused to the network operations provided by their intermittent effects need to be investigated. Regarding reserves management, regulation, scheduling, and dispatching, the intermittency in power output become a challenge for the system opera...
Hybrid optimisation and machine learning models for wind and solar data prediction
Amoura, Yahia; Torres, Santiago; Lima, José; Pereira, Ana I.The exponential growth in energy demand is leading to massive energy consumption from fossil resources causing a negative effects for the environment. It is essential to promote sustainable solutions based on renewable energies infrastructures such as microgrids integrated to the existing network or as stand alone solution. Moreover, the major focus of today is being able to integrate a higher percentages of re...
A statistical estimation of wind data generation in the municipality of Braganç...
Amoura, Yahia; Lima, José; Torres, Santiago; Pereira, Ana I.The existing wind energy potential in Portugal makes way for developing electrical energy in the northern region. In this work, wind speed data were statistically investigated using Weibull distribution to identify the characteristics of converting wind energy in Serra da Nogueira mountain in the Municipality of Braganca. An hourly wind speed time series data set from January 2002 to December 2021 have been exp...
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...
The role of anthropogenic habitats in freshwater mussel conservation
Sousa, Ronaldo Gomes; Halabowski, Dariusz; Labecka, Anna M.; Douda, Karel; Aksenova, Olga; Bespalaya, Yulia; Bolotov, Ivan; Geist, JuergenAnthropogenic freshwater habitats may provide undervalued prospects for long-term conservation as part of species conservation planning. This fundamental, but overlooked, issue requires attention considering the pace that humans have been altering natural freshwater ecosystems and the accelerated levels of biodiversity decline in recent decades. We compiled 709 records of freshwater mussels (Bivalvia, Unionida)...
