Ultra-fast Power Electronics based HVDC Circuit Breaker: A Paradigm Shift towards System Flexibility and advanced Control Features

The transition of high-voltage direct current (HVDC) transmission from point-to-point connections into multiterminal systems is essential for sustainable energy grids of the future. It improves significantly system availability, resilience, flexibility and cost efficiency. However, this change introduces the challenge of DC grid protection, where faults must be detected and cleared very quickly to ensure reliable system operation.
