SiC erdieroaleak energia eolikoan LCoEa hobetzeko

Abstract

This research identifies the wind energy as the main renewable source. In order to improve its LCoE, SiC semiconductors are proposed, together with different voltage levels and topologies. After analyzing various configurations, two that improve current LCoE are found. The first considers current cost of SiC, and uses a two level topology, achieving little improvement. The second considers the expected cost reduction of SiC due to technological maturity, and it is shown that a three level NPC is the best topology, with higher LCoE improvement.

Ikerketa honetan energia eolikoa energia berriztagarri nagusi bezala identifikatzen da. Beraren LCoEa (Levelized Cost of Energy ingelesez) hobetzeko, SiC erdieroaleak proposatzen dira, baita tentsio maila eta topologia berriak ere. Konfigurazio ezberdinak aztertzen dira, LCoEa hobetzen duten bi aurkituz. Lehenengoak, gaur egungo SiC-en kostua kontuan izanik bi mailako topologia erabiltzen du, hobekuntza txikia lortuz. Bigarrenean, teknologiaren heldutasunagatik iritsiko den kostu jaitsiera aurre ikusten da, eta hiru mailako NPC (Neutral Point Clamped ingelesez) topologia erabiltzea dela onena ikusten da, LCoE hobekuntza handia lortuz.
