Hybrid Grids: DC Technology to Unlock Capacity of AC Systems
Marius Langwasser, Marco Liserre und Hrishikesan Madhavan von der University of Kiel
Datum: 15.09.2022, 09:00 – 12:00 Uhr
The use of DC in transmission and distribution leads to an increase in efficiency and controllability, and it reduces the size and cost of the infrastructure. AC is anyway widespread, and it offers reduced challenges for protection and voltage adaptation. It is foreseen a future in which both AC and DC infrastructures will coexist into a hybrid system using the best of the two worlds. The present AC system can be optimally operated with the flexibility of hybrid system using the applications of HVDC terminals and Smart Transformer.
This webinar will start from analysing real test cases of hybrid systems, like EV-charging stations, PV-parks, wind farms, harbor and airport infrastructures, as well as the new hydrogen infrastructures. It will show how HVDC and Smart Transformer can contribute in unlocking the hidden potential of AC grids, making use of voltage control, grid forming operation, active and reactive power flow control. It will also illustrate the hybrid grid contribution to the protection against faults using its power electronic terminals. The tutorial will also briefly review the power electronics converters like DC/DC, MMC and four-leg inverters to optimally embed the flexibility of DC into AC.
System operators, manufactures, R&D from industries with the background in power electronics.
