- Hydroagriculture project - A Portuguese case studyPublication . Silva, Paulo; Felgueiras, Carlos; Almeida Santos, Adriano Manuel; Pereira, FilipeWater plays an essential role in the social fabric and comfort of society, as it plays an important role in our survival and subsistence, in its accessibility, in economic activities, and in the particular case of this study, in the manufacture of agricultural products and activities. In a developing society, and with the number of the human population increasing, consumerism takes place, resulting in an increasing need to use space, resources and food. Agriculture is an ancient activity that serves as the basis for ensuring the subsistence and resilience of the population, producing crops and different types of food, from vegetables, fruits, legumes, seeds, etc... and they all have one thing in common: The existence of water. If there are fields suitable for agriculture, but there is no water, they become unusable. Water improvement and supply projects can drastically change this situation, thus stimulating agricultural production. The analysis of this case study, the largest hydroagriculture project in Europe nowadays, aims to highlight the importance of carrying out hydroagriculture projects and the impact they can have on society, demonstrating that this project considerably increases the production of the rice harvest in Portugal through the artificial irrigation of land that previously could not be used for this purpose.
- Energy Policies, Education and Sustainable Development Goals Applied to Low Developed Countries - a Symbiotic Case StudyPublication . Martins, Florinda; Silva, Paulo; Felgueiras, Carlos; Almeida Santos, Adriano Manuel; Pereira, Filipe; Caetano, NídiaEnergy, its use and management, weighs heavily on the burden that each society can impose on a fragile balance of nature, with implications not only environmental and financial, but also social, creating jobs and improving quality of life. Devising strategies that combine these three factors are a valuable option that will yield good results, meeting the challenge of fulfilling the Sustainable Development Goals (SDGs). The most important thing is to implement the old maxim: "no one is left behind", so low developed countries are an opportunity to achieve impressive results, while allowing them to improve their way of life and their comfort. It’s often said that ‘action begets reaction’, so any positive action taken in the community can have social repercussions, such as improving the quality of education and knowledge about sustainability. This study will provide an overview of how energy management and environmental mitigation strategies can impact underdeveloped countries.
- An Energy Storage System for the Alto Douro Wind Power Plant: A Technical StudyPublication . Magalhães, Alexandre; Xavier, Celso; Felgueiras, Carlos; Pereira, Filipe; Almeida Santos, Adriano Manuel; da Silva, A. Ferreira; Silva, Paulo; Caetano, Nídia; Machado, JoséRenewable energies are crucial to meeting global demand for environmentally friendly energy at a time when fossil fuels are being cut back. In recent years, and essentially due to the reduced reserves of fossil fuels, Portugal has been promoting investment in renewable energies as a way of freeing itself from energy imports and dependence on fossil fuels. However, despite the high number of hours of sunshine per day and the use of wind and hydraulic energy, production is unstable due to climate variability. All this climate instability translates into fluctuations in the energy released to the grid. In order to minimize this problem, energy storage systems have become a key element in guaranteeing the stability of the renewable energy supply at times of low production. This article presents a feasibility analysis of a renewable energy storage system with the aim of maximizing the profitability of a wind farm located in Portugal's Alto Douro region. As a starting point, a demand analysis is presented, as well as simulations of the system's performance in terms of energy use and profitability as a function of efficiency and power. Taking these assumptions and the analysis into account, a modular lithium battery storage system with high efficiency and fast charging and discharging powers was chosen.
