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. ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Capex temporal allocation and cost recovery in long-term generation capacity expansion planning
This work revisits some interesting properties of long-term generation models and sheds light on cost-recovery properties associated to this kind of representations in the framework of marginalist remuneration electricity ... -
Probability density-based energy-saving recommendations for household refrigerating appliances
The power sector is a major contributor to anthropogenic global warming, responsible for 38 of total energy-related carbon dioxide emissions and 66 of carbon dioxide emission growth in 2018. In OECD member countries, the ... -
Analyzing mobility patterns of complex chronic patients using wearable activity trackers: a machine learning approach
This study suggests using wearable activity trackers to identify mobility patterns in Chronic Complex Patients (CCP) and investigate their relation with the Barthel Index (BI) for assessing functional decline. CCP are ... -

La ponencia presenta los resultados de parte de la investigación realizada para el proyecto europeo Horizonte 2020 RAYUELA sobre cibercrimen y menores, analizados desde una perspectiva de género. A partir de los datos ... -
Género, sexualidad y online grooming: diferencias en las estrategias de los agresores y en la percepción del riesgo de las víctimas
La ponencia presenta los resultados de una parte de la investigación realizada para el proyecto europeo Horizon 2020 RAYUELA sobre cibercrimen y menores. En concreto, los hallazgos sobre el online grooming analizados desde ... -
Design and sensitivity analysis of underfrequency load-shedding schemes of isolated power systems based on frequency stability margin
The objective of this paper is to tune the parameters of an underfrequency load shedding (UFLS) scheme based on the frequency stability margin (FSM) and compare its performance with the conventional UFLS scheme. The ...
