“…DC|hyPASim specifically investigates hybrid grid concepts with bidirectional energy flow between AC and DC grid [20]. Various studies exist on fault cases in the different grid types and the first prototypical reference systems from industry show the basic concept for specific applications for the grid form [21][22][23][24]. In terms of research, the publications address in detail the niche of simulating the efficiency for different operating points as a load in two grid forms with components available on the market.…”

Numerous research projects are investigating direct current (DC) grids for supplying energy to production plants. The motivation is the higher efficiency and lower material requirements compared to conventional grid structures, as fewer electrical conversion processes occur, regenerative energies can be coupled in more efficiently and recuperation energy can be stored better. The grid form and the associated earthing concept require different protective devices. The publication simulates two possible grid forms and compares the efficiency with an approximated power curve of a production cell. The publication gives researchers and plant planners an impression of how such a network is designed and which components influence the efficiency. It serves as a decision-making aid for the selection of the grid form and helps with the design of the electrical components.

“…The protection concept in the IT network provides for insulation monitors that ground the network to high impedance for measurement purposes and, if necessary, only issue an alarm in the first case of a fault and disconnect the network branch from the network in the second case of a fault.

“…DC microgrids require fewer conversion stages to host distributed energy resources in comparison to AC systems. The voltage regulation and power balancing are more controllable in DC systems [1, 2]. DC microgrids have already been introduced for several applications such as data centres, information communication systems and electric ships.…”
