when the AC short-circuit fault occurs in the multi-DC feed area, it may cause the failure of multi-DC simultaneous commutation, causing the huge power shortage and affecting the stability of the power grid. Hybrid DC transmission is one of the effective solutions to solve the failure of commutation...
