Ruan Moreira, a Master's student in Electrical Engineering at ISEL, participated in the 21st edition of the International Conference on the European Energy Market (EEM25), held in Lisbon. During the event, he presented a scientific paper that is now published in the IEEE Xplore digital library, consolidating his contribution to the international debate on the future of energy in cities.

Entitled "Challenges and Opportunities in the Integration of Wind Turbines in Urban Areas: A Technical and Economic Analysis," the paper was co-authored with Professors Jorge Sousa and Cristina Camus (DEEEA/ISEL). The study focuses on analyzing the technical and economic feasibility of integrating vertical axis wind turbines (VAWTs) in urban environments, where wind conditions are generally less favorable and characterized by high turbulence due to the presence of buildings.

Based on real wind data collected in an urban context, the study applied adjusted energy production models to vertical turbines, evaluating annual energy production and the levelized cost of ownership (LCOE) associated with different technological solutions. The research also included an analysis of the integration of these turbines into Renewable Energy Communities (RECs), an energy-sharing model with growing potential in urban areas. Among the models tested, the Q5 2000W proved to be the most efficient, achieving annual production of 3.82 MWh and an LCOE of R$54.10 per MWh, demonstrating potential for application in hybrid systems with solar energy and storage solutions.

Although none of the turbines studied proved economically viable in isolation, the results indicate the potential for their integrated application in energy communities or hybrid projects, where their contribution can strengthen urban energy sustainability and resilience.
