Estudio de una bomba-turbina integral
En este estudio se analiza una máquina que bombea agua de forma autónoma, es decir, sin aporte exterior de energía. Para ello se plantea el diseño y construcción de una bomba-turbina integral. Surge de la idea de realizar ... -
Retranslating Lorca s homoerotic poetry from taboo to totemic texts an analysis of ten versions of the Ode to Walt Whitman
Esta comunicación propone un análisis diacrónico de las retraducciones de la 'Oda a Walt Whitman', una poema que contiene algunas de las referencias más explícitas a la homosexualidad que permeaba su poesía y que fue el ... -
Gestión energética en sistemas eléctricos
Una correcta gestión energética de los sistemas eléctricos está directamente relacionada con una correcta planeación de los recursos, procurando garantizar la confiabilidad en el suministro. De ahí, la planeación debe ... -
Combined penetration of wind and solar generation with plug-in electric vehicles
Combining large penetration of wind and solar generation with Plug-in Electric Vehicles (PEVs) seems a promising solution for energy cost saving and emissions reduction. PEVs connected to the grid with smart charging ... -
On-line evaluation and planning tool for medium voltage-broadband over power line cells
Machine-to-Machine communications networks for Smart Grids must meet specific requirements from both technical and economic perspectives. Power Line Communications are indeed winning momentum in this area because they ... -
The influence of wind load modelling in the dynamic simulation of overhead catenary lines
Overhead catenary lines (OCL) are subjected to different loads, both those due to the interaction with the pantograph and those others mostly meteorological. The purpose of this paper is to analyze the dynamic response of ... -
An uncertainty reduction technique for short-term transmission expansion planning based on line benefits
In this article we provide a novel uncertainty reduction technique to deal with uncertainties associated to Renewable Energy Sources (RES) in Transmission Expansion Planning (TEP). For the sake of simplicity, we assume ... -
On the dynamic behaviour of catenary-pantographs subject to wind loads
Wind load effects on overhead catenary lines have acquired more importance in recent years such that the main European railways companies established limits on the velocity of the train passing through this system depending ... -
Will be always be special? Extending humanity, shrinking uniqueness
There is a vast array of characteristics that distinguish human beings from the rest of animals. We propose that these differential characteristics can be classified as: highly specific physiological traits (1), high-level ... -
Integration of renewable generation in power systems using flexibility of large industrial consumers
The integration of renewable generation in Europe is still facing some challenges to manage its intermittency and, if fully integrated in the market, additional costs may limit its feasibility. On the other hand, demand ... -
Strategic thinking for innovation policy towards sustainability. Applications in energy
Over the last decades, innovation policy-making has been widely enriched by contributions from innovation studies, which have provided new or improved conceptual frameworks that help us to better understand and deal with ... -
Analysis of operation reserves in a hydrothermal electric system with high wind power share under demand and wind power uncertainties
The paper analyses the amount of operation reserves procured in a hydrothermal system to deal with wind power and demand uncertainty. The operation planning of the system is formulated as a detailed hourly unit commitment ... -
A rational multiparty information exchange model using extensive games
It is well known that excessive intelligence is mandatory in military procedures, in companies to know about competitors, as well as in markets to decide where to invest in. However, this information is not always fully ... -
CIM as the reference data model for the UPGRID project
Distribution system operators from four countries (Spain, Portugal, Sweden and Poland) are engaged in an UPGRID project. The objective of the UPGRID project is to enable active demand and distributed generation flexible ... -
Value of perfect information of spot prices in the joint energy and reserve hourly scheduling of pumped storage plants
The value of perfect information of the day-ahead energy prices is studied in the context of the operation of a closed-loop and daily-cycle pumped-storage hydropower plant, participating in the spot market as a price-taker ... -
Mind the gap: challenges and policy options for cross-border transmission network investments
Cross-border transmission network investment requirements are expected to increase, in order to strengthen internal market integration and reach the renewable deployment policy target across Europe. This paper discusses ... -
Assessment of integrated community energy systems
Integrated Community Energy Systems (ICESs) are emerging as a modern development to re-organize the local energy systems allowing integration of distributed energy resources (DERs) and engagement of local communities. ...
