Intraday Energy Resource Scheduling for Load Aggregators Considering Local Market
Almeida, José; Soares, João; Canizes, Bruno; Razo-Zapata, Ivan; Vale, ZitaDemand response (DR) programs and local markets (LM) are two suitable technologies to mitigate the high penetration of distributed energy resources (DER) that is vastly increasing even during the current pandemic in the world. It is intended to improve operation by incorporating such mechanisms in the energy resource management problem while mitigating the present issues with Smart Grid (SG) technologies and op...
Demand Response Driven by Distribution Network Voltage Limit Violation: A Genet...
Canizes, Bruno; Mota, Bruno; Ribeiro, Pedro; Vale, ZitaThe residential sector electricity demand has been increasing over the years, leading to an increasing effort of the power network components, namely during the peak demand periods. This demand increasing together with the increasing levels of renewable-based energy generation and the need to ensure the electricity service quality, namely in terms of the voltage profile, is challenging the distribution network ...
Preliminary results of advanced heuristic optimization in the risk-based energy...
Almeida, José; Lezama, Fernando; Soares, João; Vale, Zita; Canizes, BrunoIn this paper, multiple evolutionary algorithms are applied to solve an energy resource management problem in the day-ahead context involving a risk-based analysis corresponding to the proposed 2022 competition on evolutionary computation. We test numerous evolutionary algorithms for a risk-averse day-ahead operation to show preliminary results for the competition. We use evolutionary computation to follow the ...
Demand response and dispatchable generation as ancillary services to support th...
Canizes, Bruno; Silveira, Vitor; Vale, ZitaThe current power systems, namely the low voltage distribution networks, have been suffering considerable changes in recent years. What appeared to be innovation trends nowadays due to technological advances and manufacturing cost reduction has become the new reality in the coming years. Thus, the growing trend of power generation by renewable sources has posed new challenges and new opportunities. Furthermore,...
Electric vehicles local flexibility strategies for congestion relief on distrib...
Soares, João; Almeida, José; Gomes, Lucas; Canizes, Bruno; Vale, Zita; Neto, EdisonDue to the rising concern for the environment and sustainability issues, the transportation system is experiencing important changes to its paradigm, with the increasing replacement of internal combustion vehicles by electric ones. Consequently, the electric systems need to adapt to the ever-increasing load demand from the grid and the challenge to identify driving patterns in electric vehicle users’ behavior. ...
Hour-ahead energy resource scheduling optimization for smart power distribution...
Canizes, Bruno; Soares, João; Almeida, José; Vale, ZitaEnergy resource management is a concept that should be considered in energy systems due to the significant penetration of dispersed energy resources. Thus, the efficiency in the electrical network operation can be improved and the end-user costs reduced. In this way, an energy resource aggregator plays an important role in managing the demand and generation flexibility which is meant for small producers under m...
Power Quality of Renewable Energy Source Systems: A New Paradigm of Electrical ...
Baptista, José; Faria, Pedro; Canizes, Bruno; Pinto, TiagoThe power quality delivered by the distribution companies to consumers has always been a relevant issue, especially to industrial consumers, where power quality is directly related to productivity. However, until a few years ago, power quality was mostly synonymous with continuity of service, and the main concern was the minimization of power interruptions. Since the last decade of the twentieth century, power ...

Soares, João; Almeida, José; Gomes, Lucas; Canizes, Bruno; Vale, Zita; Aranha Neto, EdisonDue to the rising concern for the environment and sustainability issues, the transportation system is experiencing important changes to its paradigm, with the increasing replacement of internal combustion vehicles by electric ones. Consequently, the electric systems need to adapt to the ever-increasing load demand from the grid and the challenge to identify driving patterns in electric vehicle users’ behavior. ...
A Sensitivity Analysis of PSO Parameters Solving the P2P Electricity Market Pro...
Vieira, Miguel; Faia, Ricardo; Lezama, Fernando; Canizes, Bruno; Vale, ZitaEnergy community markets have emerged to promote prosumers' active participation and empowerment in the electrical power system. These initiatives allow prosumers to transact electricity locally without an intermediary such as an aggregator. However, it is necessary to implement optimization methods that determine the best transactions within the energy community, obtaining the best solution under these models....
Coordination strategies in distribution network considering multiple aggregator...
Almeida, José; Soares, João; Canizes, Bruno; Vale, ZitaGiven the current state of the society in which we live, in terms of energy pollution, several objectives have been set to try to reduce environmental problems. Some of these goals include an exponential increase in production through renewable energy, and Electric Vehicles (EVs) circulating on roads. Due to this high penetration of distributed energy resources in the electricity grid, several problems may exis...
