Standardization of Power-from-Shore Grid Connections for Offshore Oil & Gas Pro...
Antunes, Tiago A.; Castro, Rui; Santos, Paulo; J. Pires, A.Offshore oil and gas (O&G) production is typically powered by local diesel engines or gas turbines. Power-from-shore (PFS) is an alternative that takes advantage of onshore renewable production and reduces greenhouse emissions but is limited to bespoke projects that are tailored to the characteristics of each site. This lack of repetition leads to an increase in the construction risk, delivery time, and lifecyc...
Engineering students education in sustainability: The moderating role of emotio...
Nogueira, Teresa; Castro, Rui; Magano, JoséIn the context of a lack of quantitative research approaching an engineering education in sustainability, this cross-sectional study aims to investigate whether efforts to promote sustainability education contribute to shaping the beliefs, attitudes, and intentions towards sustainability in a sample of Portuguese engineering schools students; in addition, this study investigates whether emotional intelligence i...
Influence of Increasing Renewable Power Penetration on the Long-Term Iberian El...
Leal, Pedro; Castro, Rui; Lopes, FernandoABSTRACT: n recent years, there has been a significant increase in investment in renewable energy sources, leading to the decarbonization of the electricity sector. Accordingly, a key concern is the influence of this process on future electricity market prices, which are expected to decrease with the increasing generation of renewable power. This is important for both current and future investors, as it can aff...
Optimal scheduling of commercial demand response by technical virtual power plants
Gough, Matthew; Santos, Sergio F.; Matos, Joao M.B.A.; Home-Ortiz, Juan M. [UNESP]; Javadi, Mohammad S.; Castro, Rui; Catalao, Joao P.S.Made available in DSpace on 2022-04-28T19:45:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-09-06; The trend towards a decentralized, decarbonized, and digital energy system is gaining momentum. A key driver of this change is the rapid penetration increase of Distributed Energy Resources (DER). Commercial consumers can offer significant contributions to future energy systems, especially by engaging i...
Providing Flexibility in Distribution Systems by Electric Vehicles and Distribu...
Gough, Matthew; Santos, Sérgio F.; Pereira, Pedro M.C.; Home-Ortiz, Juan M. [UNESP]; Castro, Rui; Catalão, João P.S.Made available in DSpace on 2022-04-28T19:51:59Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); In the recent past structural changes in the operation and topology of the electrical system have occurred. These changes have coincided with the emergence of distributed energy resources (DERs). Relating to supply side technologies, d...
Blockchain-based transactive energy framework for connected virtual power plants
Gough, Matthew; Santos, Sérgio F.; Almeida, A.; Lotfi, Mohamed; Javadi, Mohammad; Fitiwi, Desta Z.; Castro, Rui; Catalão, João P. S.; Osório, Gerardo J.Emerging technologies are helping to accelerate the ongoing energy transition. At the forefront of these new technologies is blockchain, which has the potential to disrupt energy trading markets. This paper explores this potential by presenting an innovative multi-level Transactive Energy (TE) optimization model for the scheduling of Distributed Energy Resources (DERs) within connected Virtual Power Plants (VPP...
Operation of a technical virtual power plant considering diverse distributed en...
Gough, Matthew; Santos, Sérgio F.; Lotfi, Mohamed; Javadi, Mohammad; Ashraf, Paul; Castro, Rui; Catalão, João P.S.; Osório, Gerardo J.Virtual Power Plants (VPP) have emerged as a way to coordinate and control the growing number of Distributed Energy Resources (DERs) within power systems. Typically, VPP models have focused on financial or commercial outcomes and have not considered the technical constraints of the distribution system. The objective of this paper is the development of a technical VPP (TVPP) operational model to optimize the sch...

Gough, Matthew; Santos, Sérgio F.; Pereira, Pedro M. C.; Home-Ortiz, Juan M.; Castro, Rui; Catalão, João P. S.; Santos, Sérgio F.In the recent past structural changes in the operation and topology of the electrical system have occurred. These changes have coincided with the emergence of distributed energy resources (DERs). Relating to supply side technologies, distributed generation (DG) units have become increasingly common. The demand side has also seen the growth of new technological applications, including electric vehicles (EVs). Th...
Bidding strategies for virtual power plants in the Iberian electricity market
Gough, Matthew; Santos, Sérgio F.; Oliveira, José; Chaves, Jessica; Castro, Rui; Catalão, João P. S.; Santos, Sérgio F.In recent years, the energy sector has undergone major changes, particularly in Portugal, where there is complete liberalization of the electricity sector. Like in other European countries, a market agent has been created to facilitate trading relations between producer and trader. The Virtual Power Plant (VPP) agent aims to minimize the costs to the trader and maximizes the profits of producers. In this work, ...
Compensation of unbalanced low-voltage grids using a photovoltaic generation sy...
Fernao Pires, Vitor; Cordeiro, Armando; Foito, Daniel; J. Pires, A.; Hao, Chen; Martins, Joao; Castro, RuiIn this paper, a grid-connected photovoltaic (PV) generation system is proposed with the purpose of providing support to low-voltage grids, namely through the elimination or attenuation of the grid imbalances. This compensation must consider the load types, which can be either linear or non-linear, and whether the reactive power and current harmonics generated by the non-linear loads need to be compensated in a...
