Luis Díez-Maroto received in July 2008 the M.Sc degree in electrical engineering from the ICAI-Universidad Pontificia de Comillas de Madrid. He wrote his final master thesis as an intern in Elytt Energy. The topic was the design of the ITER\'s Poloidal Field Coils. During the next year and a half he worked as a Research Engineer in Switzerland for Alstom Switzerland Ltd in a collaboration project, which involved both the ICAI in Madrid and the EPFL in Lausanne. That collaboration project became a doctoral thesis about synchronous turbogenerators static excitation improvement and impact on the grid.
