An Intelligent Coaching Prototype for Elderly Care
Martinho, Diogo; Crista, Vítor; Carneiro, João; Corchado, Juan Manuel; Marreiros, GoretiThe world ageing problem is prompting new sustainable ways to support elderly people. As such, it is important to promote personalized and intelligent ways to assure the active and healthy ageing of the population. Technological breakthroughs have led to the development of personalized healthcare systems, capable of monitoring and providing feedback on different aspects that can improve the health of the elderl...
Machine learning techniques applied to mechanical fault diagnosis and fault pro...
Fernandes, Marta; Corchado, Juan Manuel; Marreiros, GoretiWhen put into practice in the real world, predictive maintenance presents a set of challenges for fault detection and prognosis that are often overlooked in studies validated with data from controlled experiments, or numeric simulations. For this reason, this study aims to review the recent advancements in mechanical fault diagnosis and fault prognosis in the manufacturing industry using machine learning method...
Prosumer Community Portfolio Optimization via Aggregator: The Case of the Iberi...
Faia, Ricardo; Pinto, Tiago; Vale, Zita; Corchado, Juan ManuelThe participation of household prosumers in wholesale electricity markets is very limited, considering the minimum participation limit imposed by most market participation rules. The generation capacity of households has been increasing since the installation of distributed generation from renewable sources in their facilities brings advantages for themselves and the system. Due to the growth of self-consumptio...
An Optimization Model for Energy Community Costs Minimization Considering a Loc...
Faia, Ricardo; Soares, João; Vale, Zita; Corchado, Juan ManuelElectric vehicles have emerged as one of the most promising technologies, and their mass introduction may pose threats to the electricity grid. Several solutions have been proposed in an attempt to overcome this challenge in order to ease the integration of electric vehicles. A promising concept that can contribute to the proliferation of electric vehicles is the local electricity market. In this way, consumers...
Portfolio optimization of electricity markets participation using forecasting e...
Faia, R.; Pinto, Tiago; Vale, Zita; Corchado, Juan ManuelRecent changes in the energy sector are increasing the importance of portfolio optimization for market participation. Although the portfolio optimization problem is most popular in finance and economics, it is only recently being subject of study and application in electricity markets. Risk modeling in this domain is, however, being addressed as in the classic portfolio optimization problem, where investment di...
Optimisation for Coalitions Formation Considering the Fairness in Flexibility M...
Faria, Ricardo; Pinto, Tiago; Lezama, Fernando; Vale, Zita; Corchado, Juan ManuelThis paper proposes a coalitional game-theoretical model for consumers’ flexibility coalition formation, supported by an optimization model based on differential evolution. Traditionally, the participation in conventional electricity markets used to be limited to large producers and consumers. The final end-users contract their energy supply with retailers, since due to the smaller quantity available for tradin...
Multi-Agent-Based CBR Recommender System for Intelligent Energy Management in B...
Pinto, Tiago; Faia, Ricardo; Navarro-Caceres, Maria; Santos, Gabriel; Corchado, Juan Manuel; Vale, ZitaThis paper proposes a novel case-based reasoning (CBR) recommender system for intelligent energy management in buildings. The proposed approach recommends the amount of energy reduction that should be applied in a building in each moment, by learning from previous similar cases. The k-nearest neighbor clustering algorithm is applied to identify the most similar past cases, and an approach based on support vecto...
Optimal Distribution Grid Operation Using DLMP-Based Pricing for Electric Vehic...
Canizes, Bruno; Soares, João; Vale, Zita; Corchado, Juan ManuelThe use of electric vehicles (EVs) is growing in popularity each year, and as a result, considerable demand increase is expected in the distribution network (DN). Additionally, the uncertainty of EV user behavior is high, making it urgent to understand its impact on the network. Thus, this paper proposes an EV user behavior simulator, which operates in conjunction with an innovative smart distribution locationa...
A Local Electricity Market Model for DSO Flexibility Trading
Faia, R.; Pinto, Tiago; Vale, Zita; Corchado, Juan ManuelThe necessity of end-user engagement in power systems have become a reality in recent times. One of the solutions to this engagement is the creation of local energy markets. The distribution systems operators are compelled to investigate and optimize their asset investment cost in reinforcement of grids by introducing smart grid functionalities in order to avoid investments. The congestion management is the one...
Multi-agent semantic interoperability in complex energy systems simulation and ...
Santos, Gabriel; Pinto, Tiago; Vale, Zita; Corchado, Juan ManuelThis work introduces a multi-agent systems' society, in power and energy, for simulation and decision support. A semantic data model is considered to describe the domain concepts, providing a way to achieve semantic communication between the systems involved. Sharing a common vocabulary enables systems' interoperability. A semantic registration and search platform, where systems can register their services and/...
