A novel three-phase multi-objective unified power quality conditioner
Monteiro, Vítor; Moreira, C. L.; Lopes, João P.; Antunes, Carlos Henggeler; Osório, Gerardo J.; Catalão, João P. S.; Afonso, João L.The decarbonization of the economy and the increasing integration of renewable energy sources into the generation mix are bringing new challenges, requiring novel technological solutions in the topic of smart grids, which include smart transformers and energy storage systems. Additionally, power quality is a vital concern for the future smart grids; therefore, the continuous development of power electronics sol...
Towards sustainable smart cities: Integration of home energy management system ...
Ghanavati, Farideh; Matias, João C. O.; Osório, Gerardo J.Smart Homes (SHs) play a crucial role in the broader context of smart cities, contributing to the overall efficiency, sustainability, and quality of life for residents. This work presents a computationally efficient mathematical model for Home Energy Management Systems (HEMS) to activate the Demand Side Management (DSM) while minimizing the energy consumption costs of SHs. The proposed model is represented as a...
Optimal Operation of Renewable Energy Resources and Electric Vehicles in Microg...
Shahbazbegian, Vahid; Barroso-Pereira, João; Shafie-khah, Miadreza; Catalão, João P. S.; Osório, Gerardo J.Paper em fase de indexação e disponibilização na plataforma do IEEEXplore.; The adoption of electric vehicles (EVs) powered by renewable energy systems has the potential to address environmental concerns, particularly air pollution, on a global scale. Additionally, leveraging the timing and enhanced storage capacity of a significant number of EVs can significantly improve the flexibility of the electrical syste...
Optimal self-scheduling of home appliances and electrical vehicles with Home En...
Ghanavati, Farideh; Matias, João C. O.; Osório, Gerardo J.This work investigates the self-scheduling of home appliances and provides a timeline for optimal charging of Electric Vehicles (EVs) at home. The model utilizes a computer-based self-scheduling algorithm to minimize the cost of electricity while the preferences of the end-users have been considered in the model. Different electricity tariffs have been simulated in this study to assess the electricity costs of ...
Impact of uncertainty on energy hub optimization based on energy resources dist...
Azevedo, Tiago M.M.; Ghavidel, Morteza V.; Catalão, João P. S.; Osório, Gerardo J.; Santos, Sérgio F.Paper em fase de indexação e disponibilização na platoforma IEEExplore.; In recent years, significant efforts have been made worldwide, including research projects and political resolutions, to support the incorporation of renewable energy sources into power systems to help sustainable energy goals. Moreover, to build cleaner and sustainable energy systems, it is necessary to develop integrated systems, known a...
Assessing the societal impact of smart grids: Outcomes of a collaborative resea...
Ferreira, Paula; Rocha, Ana; Araujo, Madalena; Afonso, Joao L.; Antunes, Carlos Henggeler; Lopes, Marta A.R.; Osório, Gerardo J.; Catalão, João P.S.Assessing the societal contributions of research is not simple, especially for research projects that produce outputs with low technology readiness level. This paper analyses the potential societal impacts of research resulting in technologies with low maturity, but with the potential to be further developed in the long-term. It uses the case of the ESGRIDS (Enhancing Smart Grids for Sustainability) collaborati...

Bi-Level approach for flexibility provision by prosumers in distribution networks
Ramírez-López, Sergio; Gutiérrez-Alcaraz, Gillermo; Gough, Matthew; Javadi, Mohammad S.; Catalão, João P. S.; Osório, Gerardo J.The increasing number of Distributed Energy Resources (DERs) provides new opportunities for increased interactions between prosumers and local distribution companies. Aggregating large numbers of prosumers through Home Energy Management Systems (HEMS) allows for easier control and coordination of these interactions. With the contribution of the dedicated end-users in fulfilling the required flexibility during t...
Flexibility participation by prosumers in active distribution network operation
Lopez, Sergio R.; Gutierrez-Alcaraz, Gillermo; Javadi, Mohammad S.; Catalão, João P. S.; Osório, Gerardo J.This paper investigates prosumers' flexibility provision for the optimal operation of active distribution networks in a transactive energy (TE) market. From a prosumer point of view, flexibility can be provided to operators using renewable energy resources (RES) and demand response (DR) through home appliances with the ability to modify their consumption profiles. In the TE market model, the distribution system...
Towards reducing electricity costs in an energy community equipped with home en...
Javadi, Mohammad S.; Cardoso, Ricardo J.A.; Catalão, João P. S.; Osório, Gerardo J.An energy community equipped with Home Energy Management Systems (HEMSs) is considered in this paper. A local energy controller in the energy community makes it possible to transact energy between houses to support the different consumption patterns of each end-user. Price-based voluntary Demand Response (DR) programs are applied to each house to motivate end-users to alter their consumption patterns, allowing ...
