摘要

With the development of power electronics technology

the flexible DC grid will play a significant role in promoting the transformation and reformation of the power grid. It is immune to commutation failure and has high flexibility in power control and renewable energy grid integration. However

the protection and fault handling technology for a flexible DC grid is a big challenge because of the limited overcurrent capability of the converters. This paper summarizes the development of the flexible DC grid

and analyzes the fault characteristics in detail. Next

the applicability

advantages and disadvantages of the existing protection principle

fault isolation and recovery schemes are reviewed. Finally

the key problems and development trend of the future flexible DC grid are pointed out and forecasted respectively.
