From Day-Ahead to a 6-Hour Period-Ahead Market Adapted to the Stochastic Behavi...
Couto, António; Algarvio, Hugo; Lopes, Fernando; Estanqueiro, Ana; Santos, Gabriel; Lezama, Fernando; Faia, Ricardo; Carvalho, Rui; Vale, ZitaABSTRACT: The existing electricity market design challenges the fair and competitive participation of variable renewable energy sources (vRES) due to their weather dependence and limited forecasting accuracy, especially for long-time horizons, as required in the day-ahead market (DAM). These challenges impact market clearing prices and create imbalances, leading to inefficiencies, such as market-splitting event...
Analysis of Techno-Economic and Social Impacts of Electric Vehicle Charging Eco...
Bonela, Ramesh; Ghatak, Sriparna Roy; Swain, Sarat Chandra; Lopes, Fernando; Nandi, Sharmistha; Sannigrahi, Surajit; Acharjee, ParimalABSTRACT: In this work, a comprehensive planning framework for an electric vehicle charging ecosystem (EVCE) is developed, incorporating solar distributed generation (DG) and a distribution static compensator (DSTATCOM), to assess their long-term techno-economic and environmental impacts. The optimal locations and capacities of the EVCE, solar DG, and DSTATCOM are determined using an improved particle swarm opt...
The Role of Demand and Vres Flexibility in Carbon-Neutral Power Systems: Insigh...
Algarvio, Hugo; Couto, António; Lopes, Fernando; Estanqueiro, Ana; Faia, Ricardo; Santos, Gabriel; Carvalho, Rui; Faria, Pedro; Vale, ZitaABSTRACT: The goal of a carbon-neutral society by 2050 is speeding up the integration of variable renewable energy sources (vRES) in European power systems. For the expected levels of vRES, the adaptation of the demand will be crucial to manage the stochastic behaviour of these technologies. This work evaluates the impact of four prospective 2050 energy mix scenarios in the Iberian electricity market. All scena...
Portugal Offshore Wind, Green Hydrogen, and Sustainable Fuels: Power-to-X Pathways
Simoes, Sofia; Portillo, Juan C. C.; Simões, Teresa; Estanqueiro, Ana; Catarino, Justina; Costa, Paula; Oliveira, Paula; Ribeiro Pinto, Paulo JorgeABSTRACT: Portugal has a vast coastal area and significant offshore wind resources. The country has set ambitious targets and designated specific areas for offshore wind development. Current national policies are actively encouraging investment in these projects. This report compiles the latest strategies for offshore wind and green hydrogen in Portugal. It introduces the Power-to-X (P2X) concept, explores pote...
Strategic Behavior of Competitive Local Citizen Energy Communities in Liberaliz...
Algarvio, Hugo; Couto, António; Lopes, Fernando; Estanqueiro, AnaABSTRACT: The liberalization of energy retail markets empowered consumers with the ability to be part of new emerging entities, such as Citizen Energy Communities. With the increasing penetration of decentralized variable generation, communities have the advantage of incentive local carbon neutrality and sustainability. Local generation reduces transport grid usage and costs to consumers. Furthermore, worldwide...
Enterprise Europe Network (EEN) : Notas para a preparação de relatórios de sust...
Miranda, Miguel; Catarino, Justina; Couto, António; Lopes, Fernando; Afonso, JoanaRESUMO: A Enterprise Europe Network (EEN) é uma rede de serviços que tem como objetivo ajudar as empresas ou organizações a inovar e a competir no quadro internacional. As entidades que pretendam inovar, competir e estabelecer parcerias com as suas congéneres estrangeiras ou que necessitam também de instrumentos que lhes permitam avaliar o desempenho do seu modelo de negócio podem fazê-lo através desta rede. Da...
Multi-Scenario-Based Strategic Deployment of Electric Vehicle Ultra-Fast Chargi...
Nandi, Sharmistha; Ghatak, Sriparna Roy; Acharjee, Parimal; Lopes, FernandoABSTRACT: In the present work, a strategic multi-scenario EV ultra-fast charging station (CS) planning framework is designed to provide advantages to charging station owners, Distribution Network Operators, and EV owners. Locations of CSs are identified using zonal division and the Voltage Stability Index strategy. The number of chargers is determined using the Harris Hawk Optimization (HHO) technique while min...
The reform of Balancing Markets: Insights from Portugal and Spain [Abstract]
Algarvio, Hugo; Couto, António; Lopes, Fernando; Estanqueiro, AnaABSTRACT: The legislation of the European Commission for regulating the European Internal Market of Electricity (EIME) establishes measures for the electricity market harmonization. These measures are designed to encourage the active participation of renewable generation in balancing markets (BMs). RESTrade (Multi-agent Trading of Renewable Production) tool models and enables the simulation of existing secondar...
Market crises and benchmark-adjusted fund alphas in a small market context
Lopes, Fernando; Leite, Paulo; Correia, Maria Carmo; Durán-Santomil, PabloMost mutual fund performance evaluation studies interpret fund alphas as the incremental performance of managers in relation to passive benchmark indices, which should exhibit statistically insignificant alphas. However, if these indices present significant non-zero alphas, standard (non-adjusted) fund alphas are biased. This paper investigates the impact of using benchmark-adjusted alphas to assess the perform...
Non-Iterative, Unique, and Logical Formula-Based Technique to Determine Maximum...
Nandi, Sharmistha; Ghatak, Sriparna Roy; Acharjee, Parimal; Lopes, FernandoABSTRACT: In recent days, due to the increasing number of electric vehicle charging stations (EVCSs) and additional power consumption by domestic, commercial, and industrial consumers, the overall power system performance suffers, which further degrades voltage profile, reduces stability, increases losses, and may also create a voltage collapse problem. Therefore, it is crucial to predetermine a maximum loadabi...
