| Abstract |
DC power systems have been discussed for connection of renewable, small-scale power generation units. This paper addresses small-signal analysis of distributed DC power systems with emphasis on converter modeling and DC bus voltage control. Droop control is utilized to distribute the load between the source converters. The dynamic properties in terms of small-signal stability are investigated both for the converters
and for a small DC distribution system. It is found that the
converter models do not have to be taken into account. It is also
found that the negative equivalent small-signal resistance of
constant power loads does not cause problems, for the proposed
converter and DC bus parameters. |
