- Technical-Economic Evaluation of Residential Wind and Photovoltaic Systems with Self-Consumption and Storage Systems in PortugalPublication . M. Camilo, Fernando; Santos, PauloAt present, a worldwide paradigm shift has become apparent, with more and more consumers consuming the energy generated by renewable energy sources (RES) systems, such as wind or photovoltaic (PV) energy, sometimes benefiting from appropriate incentives by individual governments. Consequently, it is necessary to carry out technical–economic assessments to understand the evolution of the viability of RES investments. Within the framework of an intelligent network control environment, the smart grid (SG) concept is associated with this model, and is an important tool in the management of energy distribution networks. This article aims to make a further contribution to this issue by analyzing the economic feasibility of investing in residential consumers, considering different RES configurations. Scenarios covered in this study include: “inject all on the low voltage network/consume all on the low voltage network”, self-consumption, net-metering, and storage systems. The economic study results in this article show that self-consumption with and without the injection of excess electricity into the grid is quite attractive. The bi-hourly tariff was found to be more profitable than other tariffs. Variable tariffs (bi or tri-hourly) are more profitable than fixed tariffs. It is also concluded that investment in storage systems is not yet an economically viable solution due to the high price of energy storage.
- Fostering transversal skills: a pedagogical experience in higher educational programs of technologyPublication . Rafael, Silviano; da Rocha Vilaverde Justino, Júlia Maria; Camilo, Fernando; Lopes, Elisabete; Rafael, Silviano; Justino, Julia; Camilo, Fernando; Santos, Paulo J.; Lopes, Elisabete; Ramos, CláudiaThe short-cycle higher educational programs called CTeSP, with a strong practical and technological focus, designed to meet labour market demands, were introduced in Portugal by 2014. This paper explores the challenges faced both by the Smart Grids and Domotics CTeSP and by the Electric Vehicles CTeSP taught at Instituto Politécnico de Setúbal. The reorganization strategy applied, tailored to the characteristics of Generation Z, who prefer dynamic and engaging learning approaches, is presented. This strategy consisted of restructuring the organizational and pedagogical framework of the programs to motivate students and address the high dropout and failure rates of these CTeSP by incorporating active methodologies while fostering transversal skills like focus, adaptability, and critical thinking. These skills are essential for employability, contributing to improve the students’ academic performance. The results achieved by the implementation of this pedagogical experience are also presented and analyzed.
