Summary:

The concept of Multi-Terminal DC grids (MTDC), where DC cables connect more than two AC/DC converter stations is nowadays spreading driven by different criteria, all necessaries for large-capacity RES grid integration, such as larger flexibility of grid operation, possibility of reversible power flows, increased redundancy, and reduction of maximum power loss in case of a grid disturbance.
