Stochastic operation of isolated microgrids: aggregating-rule-based optimization versus standard approaches
Stochastic operation of power systems has risen attention of researchers as fluctuating energy sources like renewables are being increasingly integrated into existing grids. Uncertainties can be higher in small power systems ... -
The H2020 project RAYUELA: a fun way to fight cybercrime
As in the case of maieutics, this paper aims to unveil the most important goals and features of the recently funded European project RAYUELA by answering some important questions, such as: why, who, what, how, what the ... -
Simulating spatiotemporal energy technology adoption patterns under different policy designs
Recent studies found that the adoption of distributed energy resources (DER) tends to cluster spatially and temporally which has significant implications for distribution network planning. Currently, residential DER adoption ... -
Assessing electricity tariffs’ costs allocation in Saudi Arabia: upcoming challenges for a needed redesign
Redesigning electricity tariffs is a key need to enable an efficient integration of end users. The process requires moving from the plain volumetric prices still currently in force in most jurisdictions, to a more sophisticated ... -
A method for evaluating frequency regulation in an electrical grid
The first part of this two-part paper proposes a technique that consists in the measurement, through phasor measurement units, of bus frequency variations to estimate the rate of change of regulated power, and in the ... -
Modeling of third party access tariffs and portfolio gas purchases of CCGTs in the self-unit commitment problem
The structure of the operation costs of gas fired units (GFU) in real power systems is much more complex than what standard unit-commitment (UC) models consider in the state-of-the-art formulations. On the one hand, when ... -
Optimal discretization of net head dependency in heterogeneous multi-reservoir hydroelectric systems
Modeling the net head dependency of hydro power plants constitutes a serious challenge from the optimization point of view. One possible approach is to pre-establish a discrete set of representative net heads and to formulate ... -
Achieving active distribution networks through operational and architectural aspects analysis: a methodology for long-term planning
To enable the paved energy transition towards a cleaner and more sustainable living substantial changes are required at the power distribution grid level. Distributed energy resources together with the emerging actors in ... -
Technical requirements for the operation of microgrids in both interconnected and islanded mode Working group CIRED 2018-03
Considering the significant increase in projects and initiatives in Europe on microgrids connected to the distribution grid, CIRED launched a working group to address the topic of the technical requirements for the operation ... -
The role of interoperable, agnostic and flexibility enabling interfaces for DSO and system coordination
Flexibility is key for the decarbonization of the energy sector, contributing to decrease uncertainty in the operation of distribution networks, due to the connection of renewable energy sources and electric vehicles. ... -
Mechanical and electrical properties of cyanoacrylate adhesives by addition of graphene and graphene nanoplatelets nanofillers
Cyanoacrylate adhesives are of special interest because those adhesives are cured at room temperature, as well as they are able to bond a wide variety of substrates in short times. They are one-part adhesives, which cured ... -
Cianoacrilatos modificados con nanomateriales base carbono. Propiedades mecánicas y eléctricas
Los adhesivos de cianoacrilato presentan un gran interés porque curan a temperatura ambiente y son capaces de unir una gran variedad de sustratos en poco tiempo. Son adhesivos monocomponentes, que se curan sin necesidad ... -
A geo-remote IoT seismic sensing device, made of robust high-sensitivity TENGs
This work presents the best TENG (Triboelectric Energy NanoGenerator) candidate to be used as a seismic sensor and integrated into any global seismic network. Toe most optimal one out of six different compositions' was ... -
Supporting a sustainable multi-energy planning: the case study of Sulcis Iglesiente province in Italy
In the energy transition context, the design of integrated multi-energy systems is key for reaching ambitious sustainabilityobjectives. Due to the intermittent nature of the renewable energy sources, introducing technologies ... -
Tracking the silver economy. A multidimensional approach to aging societies
Aging societies constitute the largest demographic trend nowadays globally. This leads to a paradigm shift in the economic model known as the silver economy, bearing economic, societal and environmental consequences. Yet, ... -
How can theology contribute to our sustainability goals?
Religion has a responsibility in the addressing of environmental issues and the promotion of sustainability. The involvement of religious leaders such as Pope Francis and the Dalai Lama in environmental causes highlights ... -
Simplified analysis of railway track degradation by mobile applications
This analysis deals with the problem of track degradation and monitoring methods. The main aim is to discuss benefits, drawbacks, and shortages of most of them. There are several monitoring failures approach available ... -
Assessing current practices in market design to enable e-mobility in Brazil
The electrification of the transport sector will have many implications for the power sector. The latter, however, can benefit from e-mobility as a provider of system flexibility if regulation provides the correct signals ... -
