Multi-Terminal HVDC Networks - What is the Preferred Topology?
نویسنده
چکیده
This paper investigates the influence of the DC network topology with respect to two important aspects: the steady-state losses and the transient fault currents. For this, the optimal power flow in a combined AC-DC Multi-Terminal HVDC cable system based on Voltage Source Converters and the development of prospective fault currents during a pole-toground fault is simulated. The results prove that an evaluation of grid topologies must include both of the aforementioned aspects and that no network topology can optimize both at the same time.
