Electric Vehicles Charging Using Photovoltaic Energy Surplus: A Framework Based...
Cavalcante, Irvylle; Júnior, Jamilson; Manzolli, Jônatas Augusto; Almeida, Luiz; Pungo, Mauro; Guzman, Cindy Paola; Morais, HugoIn the present day, it is crucial for individuals and companies to reduce their carbon footprints in a society more self-conscious about climate change and other environmental issues. In this sense, public and private institutions are investing in photovoltaic (PV) systems to produce clean energy for self-consumption. Nevertheless, an essential part of this energy is wasted due to lower consumption during non-b...
Seasonal characterization of mercury contamination along the Portuguese coast: ...
Cardoso, Patrícia Gonçalves; Morais, Hugo; Crespo, Daniel; Tavares, Daniela; Pereira, Eduarda; Pardal, Miguel ÂngeloA seasonal characterization of mercury (Hg) accumulation in three different estuaries along the Portuguese coast (i.e. Ria de Aveiro, Tagus estuary and Ria Formosa) was done. For that, it was evaluated: (1) Hg concentrations in abiotic (water) and biotic matrices (flora and fauna); (2) the risk of consumption of local seafood species (e.g. bivalves) to human health; and (3) the environmental risk to Hg exposure...
Impact of Forecasting Models Errors in a Peer-to-Peer Energy Sharing Market
Gomes, Luis; Morais, Hugo; Goncalves, Calvin; Gomes, Eduardo; Pereira, Lucas; Vale, ZitaThe use of energy sharing models in smart grids has been widely addressed in the literature. However, feasible technical solutions that can deploy these models into reality, as well as the correct use of energy forecasts are not properly addressed. This paper proposes a simple, yet viable and feasible, solution to deploy energy management systems on the end-user-side in order to enable not only energy forecasti...
Near real-time management of appliances, distributed generation and electric ve...
Fernandes, Filipe; Morais, Hugo; Vale, ZitaConsumer-centric energy management approaches are emerging as a major solution for future power systems. In this context, intelligent home management systems should control different kinds of devices existing in the houses assuring convenient comfort levels and understanding the users’ behaviour. At the same time, the home management systems should be able to interact with other actors such as energy communitie...
Multi-Objective Electric Vehicles Scheduling Using Elitist Non-Dominated Sortin...
Morais, Hugo; Sousa, Tiago; Castro, Rui; Vale, ZitaThe introduction of electric vehicles (EVs) will have an important impact on global power systems, in particular on distribution networks. Several approaches can be used to schedule the charge and discharge of EVs in coordination with the other distributed energy resources connected on the network operated by the distribution system operator (DSO). The aggregators, as virtual power plants (VPPs), can help the s...
Adjacent Markets Influence Over Electricity Trading—Iberian Benchmark Study
Morais, Hugo; Pinto, Tiago; Vale, ZitaThis paper presents a study on the impact of adjacent markets on the electricity market, realizing the advantages of acting in several different markets. The increased use of renewable primary sources to generate electricity and new usages of electricity such as electric mobility are contributing to a better and more rational way of living. The investment in renewable technologies for the distributed generation...

Energy and Reserve under Distributed Energy Resources Management—Day-Ahead, Hou...
Soares, Tiago; Silva, Marco; Sousa, Tiago; Morais, Hugo; Vale, ZitaThe increasing penetration of distributed energy resources based on renewable energy sources in distribution systems leads to a more complex management of power systems. Consequently, ancillary services become even more important to maintain the system security and reliability. This paper proposes and evaluates a generic model for day-ahead, intraday (hour-ahead) and real-time scheduling, considering the joint ...
Dynamic Pricing for Demand Response Considering Market Price Uncertainty
Fotouhi Ghazvini, Mohammad; Soares, João; Morais, Hugo; Castro, Rui; Vale, ZitaRetail energy providers (REPs) can employ different strategies such as offering demand response (DR) programs, participating in bilateral contracts, and employing self-generation distributed generation (DG) units to avoid financial losses in the volatile electricity markets. In this paper, the problem of setting dynamic retail sales price by a REP is addressed with a robust optimization technique. In the propos...
