Optimal operation of offshore wind farms with line-commutated HVDC link connection / Montilla-DJesus, M.E. in IEEE transactions on energy conversion, Vol. 25 N° 2 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 2 (Juin 2010) . - pp. 504 - 513 Titre : Optimal operation of offshore wind farms with line-commutated HVDC link connection Type de document : texte imprimé Auteurs : Montilla-DJesus, M.E., Auteur ; Santos-Martin, D., Auteur ; Arnaltes, S., Auteur Année de publication : 2010 Article en page(s) : pp. 504 - 513 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : HVDC  power  convertors;  HVDC  power  transmission;  asynchronous  generators;  offshore  installations;  optimisation;  wind  power Résumé : This paper aims to calculate the optimal operation of offshore wind farms (OWF) working with wind turbines based on doubly fed induction generator (DFIG) technologies, and with a high-voltage dc transmission connection. The objective of the optimization problem is to maximize the active power output of the arrangement, while considering certain factors, i.e., the restrictions imposed by the available wind power, the capability curve of the DFIG, the dc-link model, and the operative conditions. The accomplishment of this aim implies setting, adjusting, and operating the system under study in order to produce a reliable and cost-efficient electric energy supply. A realistic simulation test case is performed to evaluate the proposed method, and the optimal operation analysis takes into account different wind speeds and high-voltage dc-link lengths. The results show the effectiveness of the proposed method, demonstrating the advantages of using the reactive control performed by the DFIG to manage the operational requirements of the dc link.

Problem-based learning in wind energy using virtual and real setups / Santos-Martin, D. in IEEE transactions on education, Vol. 55 N° 1 (Février 2012) 

Public ISBD [article]  in IEEE transactions on education > Vol. 55 N° 1 (Février 2012) . - pp. 126 - 134 Titre : Problem-based learning in wind energy using virtual and real setups Type de document : texte imprimé Auteurs : Santos-Martin, D., Auteur ; Alonso-Martinez, J., Auteur ; Eloy-Garcia Carrasco, J., Auteur Année de publication : 2013 Article en page(s) : pp. 126 - 134 Note générale : education Langues : Français (fre) Mots-clés : computer  aided  instruction;  power  engineering  computing;  power  engineering  education;  teaching;  wind  power;  wind  turbines Résumé : The use of wind energy is now an established fact, and many educational institutions are introducing this topic into their engineering studies. Problem-based learning (PBL), as a student-centered instructional approach, has contributed to important developments in engineering education over the last few years. This paper presents the experience of a problem-based learning approach within the context of teaching wind energy conversion systems for electricity generation at an Electrical and Electronic Master's degree level. Students were given the problem of finding the response of a wind turbine to a grid fault. Groups of three students worked on a cooperative learning project for 15 weeks, with the instructor providing resource assistance and information at all stages of the work. Two tools were designed to help the students: a virtual wind turbine simulator and a real wind turbine setup. Both experimental tools are described, and the results obtained by the students are discussed. The results show that the students valued both tools and were able to address problems at a high cognitive level.
