Measuring the digitalisation of electricity distribution systems: towards the smart grid
This paper proposes a set of digitalisation indicators focused on measuring the different digital capabilities and infrastructure of electricity distribution systems, as opposed to previous indicators which have mainly ... -
Modelling single price area interconnections in the EU electricity market
The EU Internal Market for Electricity is facing important changes to ensure a smooth transition to a fully decarbonized system by 2050, where non-dispatchable renewable energy sources (RES) have a crucial role to play. ... -
Minimum-cost-based capacity planning: does annualized capital expenditure always yield full cost recovery with marginal pricing? (extended version)
This paper compares three ways of dealing with the annualization of investment cost (CapEx) when analyzing minimum-cost capacity expansion planning. The first is the classic single-year annualized cost representation, while ... -
The devil is in the details. An evaluation of intrazonal congestion management methods in Europe
In the European context, the topic of cross-border capacity allocation and congestion management has received considerable attention. However, intrazonal congestion management has largely remained an operational decision ... -
African power pools: institutions, reforms, issues and challenges
In Africa, regional electricity markets are being developed through the establishment of five power pools that aim to promote electricity trade between countries in different regions. However, experiences from global ... -
Batteries ageing impact on economic medium-term dispatch models of electricity generation
The rising interest in energy storage systems (EES), due to their ability to mitigate power fluctuations, enhance system flexibility and improve the reliability of variable renewable technologies. However, this interest ... -
Integrating mobility and power system expansion models to assess the role of fuel cell vehicles in the Iberia energy transition
CEVESA is a market model for the long-term planning and operation of the Iberian Electricity Market (MIBEL). It is based on interconnected price-zones with implicit capacity allocation for market coupling and market splitting ... -
A Cournot joint equilibrium model for the medium-term hydrogen and electricity markets
Hydrogen has the potential to play a significant role in the energy transition, helping, on the one hand, to decarbonize hard-to-abate sectors such as the energy industry and, on the other hand, as a further alternative ... -
Predictive traffic regulation algorithm for a railway mass transit line equipped with CBTC
The main objective of the paper is the development of a twin model of a metro line for the testing and analysis of train traffic regulation strategies. In particular, a traffic regulator with continuous communication has ... -
Multistage distribution expansion planning leveraging load flexibility
This paper presents the multistage distribution network planning problem, utilizing conventional and non-conventional expansion measures. Here, conventional network expansions, i.e. transformers and lines installations, ... -
A vector-based flexible-complexity tool for simulation and small-signal analysis of hybrid ACDC power systems
This paper presents VFlexP, an open-source, vector-based tool for the time domain simulation, static analysis, and small-signal analysis of hybrid ACDC power systems, built upon MATLAB-Simulink. Unlike existing tools such ... -
Energy poverty definition and measurement in the Iberian peninsula: can interchange lead to improved diagnosis
Energy Poverty affects millions of people in Europe, with higher incidence and intensity in southern European countries like Portugal and Spain. Both nations have developed national strategies, proposing an official ... -
Indicators for suitability and feasiblity assessment of flexible energy resources
Recommender systems are crucial in optimizing building energy consumption by offering personalized advice based on data analytics and user preferences. However, the need for explainable systems is emphasized to justify ... -
Mitigating the impacts of community energy trading on low voltage distribution networks by considering contracted power cost
Driven by environmental and economic motives, different distributed energy resources (DERs) are being installed at a fast pace. The high penetration levels of DERs could result in technical issues at low voltage distribution ... -
Optimal planning and operation of energy community DERs considering local energy trading and uncertainties
Local energy trading between customers in energy communities (ECs) received significant interest from academia and industry as a promising approach for managing a large number of distributed energy resources (DERs) and ... -
The role of technologies in dealing with energy poverty issues
The dual green and digital transition is both a challenge and an opportunity to improve citizens' well-being while reducing GHG emissions. However, social aspects must be adequately considered when designing and implementing ... -
On the use of pay-as-bid auctions in California: some criticisms and alternative proposal
This document presents some ideas regarding the use of the pay-as-bid pricing rule in multi-unit auctions. In particular, we focus on electricity markets and on the proposals for adopting this kind of mechanism in the ...
