Forecast Ratio and Security Analysis of Rating Forecasting Methods in an Overhead Line
(The Institution of Engineering and Technology, 2017-01-26)
The actual line rating in overhead lines varies with weather conditions. When a utility defines a rating value for the operation of the line, it takes into account both the security and the forecast ratio. The defined ...
Field validation of gap-type overhead conductor creep
(Elsevier, 2018-09-11)
Gap-type overhead conductor sag-tension calculations based on experimental conductor creep tests are based on stress-strain and metallurgical creep tests. Although for bi-metallic conductors, these tests are carried out ...
Uncertainties in the Testing of the Coefficient of Thermal Expansion of Overhead Conductors
(MDPI, 2020-01-14)
Overhead lines can be replaced by high temperature low sag (HTLS) conductors in order
to increase their capacity. The coe cients of thermal expansion (CTE) of the HTLS conductors
are lower than the CTE of conventional ...
Fuel cell-based CHP system modelling using Artificial Neural Networks aimed at developing techno-economic efficiency maximization control systems
(Elsevier, 2017-02-08)
This paper focuses on the modelling of the performance of a Polymer Electrolyte Membrane Fuel Cell
(PEMFC)-based cogeneration system to integrate it in hybrid and/or connected to grid systems and
enable the optimization ...
Model for optimal management of the cooling system of a fuel cell-based combined heat and power system for developing optimization control strategies
(Elsevier, 2017-12-18)
This paper is focused on the development of a model for achieving optimal control of the cooling system of a polymer electrolyte membrane fuel cell (PEMFC)-based cogeneration system. This model is developed to help facilitate ...
Optimized Energy Management Strategy for Wind Plants with Storage in Energy and Reserve Markets
(IOP Publishing, 2019-05-21)
This paper addresses the joint operation of wind plants with energy storage systemsin multiple markets to increase the value of wind energy from an economic and technical point of view. The development of an optimized ...
Analysis of Local Measurement-Based Algorithms for Fault Detection in a Multi-Terminal HVDC Grid
(MDPI, 2019-12-17)
One of the most important challenges of developing multi-terminal (MT) high voltage direct current (HVDC) grids is the system performance under fault conditions. It must be highlighted that the operating time of the ...
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 ...
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 ...
