Abstract
and protection of medium power DC networks in an active
distribution power system considering fault current limiting,
system control and converter design. Reduced terminal
capacitance and extra DC impedance are used to limit DC fault
current and reduce the required converter current rating for
medium power DC networks. An adaptive DC power stabilizer is
proposed to alleviate possible system instability brought by the
fault current limiting settings in the presence of constant power
load. The effect of the current limiting method and the proposed
stabilizer on DC fault current and stability enhancement are
validated by simulation studies using a simple two-converter DC
network and a multi-terminal DC network in an active
distribution power system
