Automatic classification and permittivity estimation of glycerin solutions using a dielectric resonator sensor and machine learning techniques
This paper presents the application of a dielectric resonator sensor to characterize glycerin solutions. Air and nine different concentrations were measured within a relative permittivity range from 1 to 78.3. Principal ... -
The economics of fossil decarbonisation in industrial processes for a targeted policy design
Current industrial processes, especially those in the basic material sector, rely on fossil fuels and feedstock. Hence, transforming the industrial sector with low-emission processes for a climate-neutral economy implies ... -
Energy burden in a time of crisis: analysing the evolution of electricity bills in Spanish households
The current global energy price crisis has caused unprecedented increases in electricity and gas bills. To contrast this rise, the Spanish government implemented several ‘emergency measures’ to protect energy consumers.This ... -
Frequency stability constrained unit commitment in isolated power system with high penetration of renewables energy sources
Islands are facing considerable challenges in meeting their energy needs in a sustainable, affordable and reliable way. This is mainly due to the isolated nature and small size of island power systems and the cost of the ... -
Bid forwarding as a way to connect sequential markets: opportunities and barriers
When markets trade compatible products, the overall procurement efficiency can be increased by forwarding the unused bids from one market to another by a predefined market operator. This process, known as bid forwarding, ... -
Integrating the central-dispatch markets into the European balancing platforms: main lessons learnt and challenges
In European balancing markets, there are two co-existing market models based on the adopted dispatch process. In a self-dispatch model, the market players are in charge of determining the operational schedule of their ... -
Improved hybridization of CEVESA MIBEL market model based on real market data
This paper presents a new hybridization approach to improve CEVESA, a multi-zonal hydro-thermal equilibrium model for the joint dispatch of energy and secondary reserve capacity for the Iberian Electricity Market (MIBEL). ... -
Enabling the seamless coordination and synchronization of microgrids using batteries
Microgrids (MGs) have become a commonly used way for renewable energy sources (RESs) integration in electrical distribution systems. These MGs are formed of a mix of RESs and batteries that can operate either in grid-forming ... -
Scalable uncertainty aware ancillary services procurement tool for active distribution systems
Achieving carbon neutral power systems is pushing for higher penetration of distributed energy resources (DER) in existing distribution systems. Accordingly, sophisti-cated, yet, practical tools for the optimal operation ... -
Regulatory learnings from EU funded flexibility projects. the i-DE case: preparing the future DSO.
Three European projects CoordiNet, OneNet and BeFlexible are playing a key role in developing key solutions to enable the use of flexibility in the electricity network, but also in particular i-DE's (leading Spanish DSO ... -
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 ... -
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 ... -
