Real-time operation of dynamic virtual power plants: integrating re-dispatch optimization with the dynamic DVPP model
For the real-time operation of DVPP, a real-time simulation tool is utilized to describe the dynamics of the system. A fast, scalable, rolling-time horizon redispatch optimization algorithm implemented and executed through ... -
So good but so far away? How institutional distance shape subsidiaries’ reputation building from multinationals’ corporate social responsibility
Multinational Enterprises (MNEs) build a reputation across their host countries using Corporate Social Responsibility (CSR). Corporate reputation results from the host country stakeholders’ judgment on the reliability of ... -
Critical energy utopias and futures consciousness
This paper examines how futures consciousness may be impacted by the literary genre I call “critical energy utopias.” Like climate fiction (cli-fi) and solar punk, critical utopias can help narrate the transformations of ... -
A framework for measuring stakeholder engagement in energy transitions projects
Measuring stakeholder engagement in energy projects is fundamental to identify most promising engagement strategies, to track project engagement progress, report project performance and learn how to improve the performance ... -
Ingeniería inversa sobre protocolos de radiofrecuencia para sistemas Remote Keyless Entry
El sector del automóvil ha sido un objetivo para los ciberdelincuentes desde hace décadas. La nueva normativa que ha entrado en vigor en la industria del automóvil obliga a los fabricantes a tener en cuenta la ciberseguridad ... -
Dynamic risk assessment tool for customer IoT infrastructures for smart grids
IoT devices are becoming increasingly ubiquitous in today’s society. However, they are usually weak in terms of cybersecurity. This vulnerability to cyberattacks makes them an attractive target for hackers. Manipulation ... -
Threat models for vulnerability analysis of IoT devices for manipulation of demand attacks
The development of Internet of Things technologies has brought, along with new opportunities, new types of risks to the table. This is exemplified by attacks like the distributed denial of service from the botnet Mirai. ... -
Dataset para el análisis de eventos maliciosos en sistemas windows basados en la matriz de mitre
La evaluación de los sistemas de detección y prevención de amenazas requiere de la existencia de datasets que se encuentren actualizados y correctamente diseñados conforme las amenazas más comunes. Actualmente, la ... -
Multimode power oscillation damping controller synthesis using vector fitting
Low-frequency oscillations in power systems have been commonly damped by power system stabilisers based on lead-lag transfer functions. These stabilisers can be implemented in the control loops of synchronous generators ... -
Re-synchronisation of a microgrid to the main grid using multi-agent secondary control
The idea of having self-powered microgrids has often been proposed to take full advantage of distributed generation resources. These microgrids can work either isolated from or connected to the main grid, which brings a ... -
Power flow algorithm using a second-order differentation approach
Load flow is the key tool for most of the studies related with electric power systems operation and planning. For a given electric network and power dispatch, power flow provides the state variables of the system, i.e. bus ... -
Analytical frequency-constrained UC for island power systems
This paper presents a frequency-constrained unit commitment (FCUC) formulation for island power systems. The timely activation of spinning reserve is key to guaranteeing frequency stability in the operation planning phase. ... -
Design and comparison of UFLS schemes of isolated power systems based on frequency stability margin
Increasing penetration of renewable energy resources (RES) affects stability and, in particular, frequency stability of island power systems like the Canary Islands. System protection involves underfrequency load shedding ... -
Enhancing RES grid connection via dynamic hosting capacity and hybridization
Decarbonizing the energy sector requires the rapid integration of significant renewable generation capacity into electricity grids. The enhancement of existing grid capacity, avoiding reinforcement, represents an interesting ... -
Scalability analysis of a wireless M-Bus system for smart metering and sensoring
Wireless M-Bus communication protocol has emerged as one way of implementing smart metering for smart grids and cities. To determine possible applications of this technology in these contexts, its scalability and replicability ... -
Climate-related credit risk: Rethinking the credit risk framework
Climate change poses a significant financial risk to economic agents, as well as a potential systemic risk threat due to uncertainty and non-linearity of the transition risks to a zero-carbon economy. This article conducts ... -
Gender, racialization and sexual orientation: a common ground for aggression in the form of cyberbullying and online hate speech
Bullying and its virtual form, cyberbullying, are often presented as universal phenomena that can be suffered by any student. However, if we look at the risk factors, we find issues such as gender, race or sexual orientation ... -
Who shares fake news? Consumption, verification and dissemination of information among adolescents
The main objective of this study is to find out how adolescents access and share online information, in particular fake news. To achieve this goal, eight focus groups were conducted in five European countries (Portugal, ... -
State relevance and modal analysis in electrical microgrids with 100 grid-forming converters
In traditional power systems, dominated by syn-chronous generators, the separation between time scales is well-known due to the physical response of the generating units. However, the fast-growing deployment of renewable ...
