“…Hybrid approaches of different storage systems, as compressed air and supercapacitors, are also under investigation [16]. Research can also be focused on storage solutions for special generators [17]- [19] or the influence of the place of the storage in the system [20]. The converters in such systems are also a topic under investigation [21]- [23].…”

Abstract-Diesel generators in small electricity grids are mostly not used in a very efficient way. The reason for this is twofold. First of all, the efficiency of a diesel generator is dependent on the ratio determined by the average power divided by the peak power of the generator. The smaller this ratio is, the lower the efficiency. Furthermore, some loads can regenerate energy. In small grids, this energy is mostly not needed elsewhere and should be dissipated. A solution solving both problems previously mentioned is using an energy storage device in the system. This storage can be used for peak shaving and storing regenerated energy. This paper focuses on a generator-set with energy storage. Six different power management strategies are discussed. Calculation of the costs shows that adding an energy storage device lowers the cost for all methods. Verification with simulation and experiments has been carried out.

Deseo expresar mi más profundo agradecimiento a mis padres por todo el amor y cariño que me han dado a lo largo de mi vida, y que me ha llevado a ser la persona que soy hoy en día. Por supuesto también a mis hermanos, que aunque a veces discutimos, siempre llegamos a un nuevo lugar de encuentro. También a mis directores de Tesis, sin cuya sabiduría, paciencia y apoyo no se hubiese podido terminar el presente trabajo. Y no puedo olvidar a todos los amigos que he ido encontrando a lo largo de los años en la universidad y los buenos momentos vividos juntos. En especial a Andrés Vallés y Salvador Orts, por toda la ayuda que me han prestado desde siempre, y sobre todo, por la amistad que nos une.Gracias.
