To make it possible the feeding both of DC and AC...
This paper presents some considerations about fuel cell energy utilization instead of classical backup sources for substation ancillary services. The main necessity of substation ancillary services is to stay supplied and one modern solution to supply the substation ancillary services using a clean energy is compared versus an actual classical solution. The key elements of the investigated solution...
