Advanced Protection Technologies of a Cable Dominated Network with large Scale Power Electronics

In recent, due to the increasing application of renewable energy generations, active loads, FACTS and HVDC, it is expected that the Danish power system is in a transition towards a power system with very high level (even 100%) of power electronics (PE) integration. On the other hand, the Danish government has decided that a large part of the Danish power transmission system should be transformed into underground cables (UC). Such two transitions of the Danish power system will provide very different short-circuit power during faults in comparison with a conventional overhead-line-based and synchronous generators dominated power system which make the future Danish power system a unique case that has not been well studied before.

Therefore, this project is to comprehensively investigate the protection performance of the future Danish power system towards 100% PE based and UC dominated, and develop novel planning and operation methods.
