A Note on the Normalization of Spanish Electricity Spot Prices
(IEEE, 2015-07-21)
Merit order of renewable generation has produced
an increasing, relevant number of zero values in Spanish electricity
spot prices since 2010, in contrast with the rest of markets
which rarely present zero values. This ...
Cálculo de distancias de seguridad en la repotenciación de líneas de corriente alterna con tecnología HVDC
(Federación de Asociaciones de Ingenieros Industriales, 2016-03-19)
During the last decades, the combination of several factors
(rapid growth of electricity consumption, deregulation of the
electricity market and increase of distributed generation)
has led to important changes in power ...
Electric Arc in Low-Voltage Circuit Breakers: Experiments and Simulation
(IEEE, 2017-01)
The aim of this paper is to present a further
approach for analyzing the air electric arc in low-voltage
circuit breakers (LVCBs). In order to achieve that, a new
simulation model and experimental tests have been carried ...
Professional skills development in engineering education at the university of the Basque country: Problem or Project Based on Learning?
(DYNA, 2019-01)
[EN]In engineering education, when choosing methodologies to promote the development of professional skills that satisfy both, the requirements of the evaluation agencies and employers, two options, among others, are being ...
Risk-based optimal distribution of power reserves in wind power plants
(Wiley, 2016-07-22)
This paper employs the Conditional Value-at Risk, largely used in financial risk management, to specify the power reservecapacity of a wind power plant (WPP) under a risk metric. Evidences are shown here that other popular, ...
Current procedures and practices on grid code compliance verification of renewable power generation
(Elsevier, 2017-05)
Generation assets applying for grid connection must comply with certain grid code requirements. Grid code
compliance verification shall include revision of documentation covering technical data and models, checking ...
Joint cost of energy under an optimal economic policy of hybrid power systems subject to uncertainty
(Elsevier, 2015-08-01)
Economical optimization of hybrid systems is usually performed by means of LCoE (levelized cost of energy) calculation. Previous works deal with the LCoE calculation of the whole hybrid system disregarding an important ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
