In response to the communication delay and delay jitter issues of existing differential protection methods for distribution network with distributed generation (DG)

a differential protection structure for distribution network based on 5th-Generation (5G) communication technology has been proposed

combining 5G communication technology with improved time dynamic bending algorithm for differential protection in distribution network with distributed power sources. The dynamic time warping algorithm is optimized by introducing weighted functions and global path constraint strategies

improving protection reliability and calculation speed. The superiority of the proposed protection method is verified through example analysis. The results indicate that

the proposed method can quickly perform protection in differential protection

effectively reducing communication delay

delay jitter and protection action time

which is capable of adapting to future complex distribution network structures with distributed power sources

providing certain assistance for the development of 5G + smart electricity.
