- Análise técnica do impacto da mudança de hora legal na penetração da geração de energia renovável não controlável no consumo em Portugal continentalPublication . Silva, João M. Henriques da; Couto, António; Duque, JoaquimRESUMO: A análise técnica do impacto da alteração do regime de hora legal no consumo de energia em Portugal Continental, suprido pela geração de energia renovável não despachável (VRE) e, por isso, não regulável em função do consumo, procurou averiguar a presença de eventuais benefícios que poderiam decorrer dessa alteração. Contudo, neste domínio de análise, não foi detetada a existência de qualquer vantagem significativa decorrente da alteração do regime de hora legal vigente para quaisquer outros regimes de hora legal analisados.
- Aumentar os impactos transformadores das inovações sustentáveis: evidência das tecnologias de energia renovável marinhaPublication . Fontes, Margarida; Bento, Nuno; Sousa, Cristina; Barbosa, Juliana; Santos, Hélder; Sá Marques, TeresaRESUMO: Tanto as empresas como os decisores políticos procuram aproveitar as oportunidades para criar atividade e emprego na transição para uma economia de baixo carbono. Os co-benefícios da transição sustentável são cada vez mais investigados pelos ganhos potenciais que proporcionam aos países e pela sua contribuição para a aceitação social da transição sustentável. Em particular, o desenvolvimento e a experimentação de novas tecnologias energéticas deverão criar efeitos de aprendizagem localizados que melhorem os custos e o desempenho dessas tecnologias, permitindo, ao mesmo tempo, que os atores criem capacidade e diversifi quem para novas atividades necessárias à cadeia de valor emergente. Este Policy brief esclarece como a política tecnológica e a estratégia industrial se podem complementar, de modo a criar recursos coletivos para acelerar o progresso de tecnologias emergentes, obtendo vantagens competitivas, e transformando os sectores existentes.
- Building new indicators for researchers’ careers and mobility based on electronic curriculum vitae: the case of the DeGóis platformPublication . Fontes, Margarida; Assis, José; Araújo, Emília; Bento, Sofia; Henriques, Luísa; Pirralha, André; Santos, LeonelThere are currently two main databases in Portugal regarding researchers’ electronic CVs: • the FCT-SIG (Council for Science and Technology-Information and Management System) – hereafter called the FCT Information System, and • the DeGóis Platform Although this report will be concentrated on discussing the DeGóis Platform, since the latter will prevail in the medium/long term, replacing the former one, we believe it is useful to shed some light on the FCT Information System, as it still comprises the bulk of researchers’ electronic CVs in Portugal.
- Characterization of new flexible players: Deliverable D3.2Publication . Chrysanthopoulos, Nikolaos; Papadaskalopoulos, Dimitrios; Strbac, Goran; Schimeczek, Christoph; Kochems, Johannes; Vries, Laurens de; Sanchez, Ingrid; Algarvio, Hugo; Couto, António; Pinto, Tiago; Hernandez-Serna, Ricardo; Johanndeiter, Silke; Estanqueiro, AnaABSTRACT: The subject matter of this report is the analysis of the electricity markets’ actors’ scene, through the identification of actor classes and the characterisation of actors from a behavioural and an operational perspective. The technoeconomic characterization of market participants aims to support the upcoming model enhancements by aligning the agent-based model improvements with the modern market design challenges and the contemporary characteristics of players. This work has been conducted in the context of task T3.2, which focuses on the factorization of the distinctive operational and behavioural characteristics of players in market structures. Traditional parties have been considered together with new and emerging roles, while special focus has been given on new actors related to flexible technologies and demand-side response. Among the main objectives have been the characterization of individual behaviours, objectives and requirements of different electricity market players, considering both the traditional entities and the new distributed ones, and the detailed representation of the new actors.

- Design of ancillary service markets and products: Challenges and recommendations for EU renewable power systems: Deliverable D3.3Publication . van der Welle, Adriaan; Morales-España, Germán; Sijm, Jos; Serna, Ricardo Hernandez; Kochems, Johannes; Couto, António; Algarvio, Hugo; Kiviluoma, Juha; Vries, Laurens de; Estanqueiro, AnaABSTRACT: The overall objective of the current study is to analyse the implications of the transition towards a renewable, climate-neutral power system in the EU for the demand and supply of ancillary services (AS) of this system in general and for the market design and related EU regulation of these services in particular. The study focuses predominantly on electricity balancing services (‘frequency control’). However, other ancillary services – not ably reactive power services (‘voltage control’) and system restoration services (‘black start’) – are, to some extent, considered as well. More specifically, the study analyses in particular (i) the current situation (‘base case’) of ancillary (electricity balancing) services in the EU, (ii) the future situation (‘towards a 100% renewable EU power system’) of these services, and (iii) the major challenges and recommendations for the main ancillary services markets in the EU in order to improve the performance of these markets in the coming years, i.e. up to 2030 and beyond.
- Development of DLR analysis and power system models: Deliverable D3.1Publication . Algarvio, Hugo; Duque, Joaquim; Couto, AntónioABSTRACT: This deliverable presents the work developed by LNEG as part of the R&D activities of the project OPTIGRID - Methodology for the dynamic line rating analysis and optimal management of power networks. According to the plan activities of Tasks 3.1 and 3.2, the main objective of this deliverable is to integrate the mathematical model for the Dynamic Line Rating (DLR) analysis in the optimal power flow model for a generic AC power system, previously developed in LNEG. The main limiting factor for the transmission capacity of overhead lines (OHLs) is usually defined by a thermal constraint. For OHLs several effects are present, some with a positive contribution while others can lead to the potential congestion of the electrical networks. The seasonal line rating (SLR) methodology, traditionally used by the system operators to ensure that the grid does not operate over the maximum pre defined conductor temperature, determines the line’s ampacity from constant weather conditions using: 1) seasonal basis information or 2) conservative weather conditions. These conditions usually underestimate the real transmission capacity of OHLs. Thus DLR analysis allows assessing more realistic current limits for the power lines could present a method to deal with potentially congested electrical networks enabling the optimal integration of distributed renewable power generation.
- Dissemination Activity Report - 5th Edition: Deliverable D7.4Publication . Sousa, Filipe; Simões, TeresaABSTRACT: This report presents the dissemination activities conducted in the scope of TradeRES project during the last 10 months, and the main highlights of the overall project. The content of this report follows the dissemination and exploitation plan (D7.2) and corresponds to an update of the information reported in the previous editions of the progress dissemination report (D7.4 – Dissemination Activity Report). This report describes the key target groups and the key performance indicators (KPI) achieved at the end of the project - general promotion of the project, social media, traditional media promotion and communication of regular news and announcements, publication in scientific journals, special book chapters and participation in workshops and international conferences, organization of scientific events, conferences, workshops, thesis, and dissemination material. Finally, an analysis of the most relevant activities and KPIs is presented in the conclusions. During the development of the project, there was the need to revise the accounting methodology, at the beginning of the 4th year, and the new metrics were applied to the whole duration of the activities. The extension period that was granted to the project, proved to be very valuable, as it allowed for a more comprehensive dissemination of the outcomes, provided additional time to achieve efficient and accurate results, and enabled the preparation of dissemination materials in a more robust manner. The last year of the project was very productive enable to address some KPIs that were missing and further enhance others. In addition, although the great majority of the KPIs were already achieved at the beginning of the last reporting period, the extension of the project, enabled to overcome the foreseen outcome. For example, it was possible to publish 40 conference papers and 40 journal papers, in both cases 100% above the targets outlined in the plan.
- Dissemination Activity Report: 4th EditionPublication . Simões, Teresa; Sousa, FilipeABSTRACT: This report presents the dissemination activities conducted in the scope of TradeRES project during the fourth year. The content of this report follows the initial dissemination and exploitation plan (D7.2) and corresponds to an update of the information reported in the previous editions of the progress dissemination report (D7.4 – Dissemination Activity Report). This report describes the highlights of the dissemination activities that occurred in the reporting period, and the stakeholders and target groups, fulfilment, and progress indicators. It also presents, detailed Key Performance Indicators (KPIs) lists including general promotion of the project, social media, traditional media promotion and communication of regular news and announcements, publication in scientific journals, special book chapters and participation in workshops and international conferences, organization of scientific events, conferences, workshops, thesis, and dissemination material. Finally, conclusions on the achievement of the defined KPIs and identification of points to be improved during the 4th year of the project are presented. Following the discussions held during the WP7 monthly meetings during this period, there was the need to revise the accounting methodology for KPIs, to provide a more accurate representation of the metrics. It was agreed by the participant partners to implement these changes from this deliverable forward. For instance, the previous approach considered only “one” entry for conference participation, regardless of whether it involved one or multiple partners, which didn’t reflect the number of effective participations. This adjustment ensures a more real approach on the nature of each participation, considering the involvement of multiple partners, associated costs, and exposure in each event. The approved extension of the project until the end of 2024, provides a valuable opportunity to deepen research and elevate the dissemination metrics (KPIs). This report will be updated at the end of the project, with final status, and overview of the entire project. The additional time allow to share the project’s outcomes more comprehensively, aiming to overcome the gaps and contribute even further to the dissemination of knowledge of the project field. It is important to note that some KPIs are challenging to quantify accurately because of their subjective nature. Therefore, in this context, they are treated as estimates; for instance, determining the exact number of people reached during a specific event may fall into this category.
- Market design for a reliable ~100% renewable electricity system: Deliverable D3.5Publication . Morales-España, Germán; Algarvio, Hugo; Vries, Laurens de; Faia, Ricardo; Hernandez-Serna, Ricardo; Johanndeiter, Silke; Couto, António; José, Débora Regina S.; Papadaskalopoulos, Dimitrios; Lopes, Fernando; Strbac, Goran; Sanchez, Ingrid; Kochems, Johannes; Helistö, Niina; Chrysanthopoulos, Nikolaos; Estanqueiro, AnaABSTRACT: The goal of this report is to identify in which respects the design and regulation of electricity markets needs to be improved in order facilitate a (nearly) completely decarbonized electricity system. It provides a basis for scoping the modeling analyses that are to be performed in subsequent work packages in the TradeRES project. These simulations will provide the basis for an update of this deliverable in the form of a more precise description of an all-renewable electricity market design. In this first iteration1 of deliverable 3.5, we analyze how the current design of electricity markets may fall short of future needs. Where there is a lack of certainty about the best market design choices, we identify alternative choices. Alternatives may concern a choice between policy intervention and no intervention or different intervention options. Section 2 outlines current European electricity market design and the key pieces of European legislation that underlie it. The European target model is zonal pricing with bidding zones that are defined as geographic areas within the internal market without structural congestion. That implies that within one bidding zone electricity can be traded without considering grid constraints and there are uniform wholesale prices in each zone. The main European markets are Nordpool, EPEX and MIBEL. Trading between zones in the European Price Coupling Region occurs through an implicit auction where price and quantity are computed for every hour of the next day, using EUPHEMIA, a hybrid algorithm for flowbased market coupling that is considered the best practice in Europe at this time.
