Voltage Control and Load Sharing in DC Distribution Systems

In English This paper addresses voltage control and load sharing in DC distribution systems. At present, DC
distribution systems are utilised in, for example, telecommunication systems. Future applications
could also involve distributed power systems based on renewable energy sources. The dynamic and
stationary properties of voltage droop control and its load sharing abilities are investigated. The DC
bus voltage droop controller gain is selected so that the loading of each source converter is equal in
per unit. Both experimental and simulation results verify the operation. Experimental results
regarding fault detection in DC distribution systems are also presented.
