Premium power quality with DG integrated DC systems

The necessity to ensure premium power quality to the sensitive customers and development of distributed generators (DG), have determined the consideration of realizing a low voltage DC distribution system. This low voltage DC distribution system will represent a premium power network that combines the advantages of the equipments used for improving the voltage quality and supply continuity, and uses sustainable power generating units. The paper deals with the energy management and dynamic analysis of the DC system with interconnect distributed generators and storage devices, focusing on guaranteeing high voltage quality levels in case of AC mains disturbances.
