(Sin editorial (Bolonia, Italia), 23/06/2003)Voltage stability is concerned with the ability of a power system to maintain acceptable voltages at all buses. A measure of the power system voltage stability is the distance to the saddle node bifurcation of the power ... -
A long-term prospective for the Spanish electricity system
(Institute of Electrical and Electronics Engineers (Madrid, España), 2010-06-23)The main objective of this paper is to present the preliminary results obtained within the SUSPLAN EU Project2, regarding the integration of increasing levels of Renewable Energy Sources (RES) into the future Spanish energy ... -
A machine learning method applied to the evaluation of the condition in a fleet of similar vehicles
(European Safety and Reliability Association; International Association for Probabilistic Safety Asse (Venecia, Italia), 2020-11-01)This paper presents a procedure for anomaly detection of temperatures in different key components of the power train in a fleet of similar vehicles. The anomaly detection is based on the characterization of the typical ... -
A medium-term operation model for a natural gas system
(Sin editorial (Zagreb, Croacia), 2011-05-25)During last decades, consumption of natural gas has been continuously increasing worldwide. Hence, infrastructure has been developed to transport the natural gas from the well to the final consumer. Natural gas chain value ... -
A method for estimating stress of a failure mode in a component due to abnormal behaviour observed in a wind turbine
(Det Norske Veritas, Norway and Centre for Industrial Asset Management (CIAM), University of Stavange (Stavanger, Noruega), 2011-05-30)Sometimes an industrial component can be affected during its life by several external and internal conditions that can induce failure modes, or at least, contribute to the presence of one or more symptoms ... -
