High penetration of renewable energy sources (RES) into power systems result in challenged system operation and control while the interaction between transmission and distribution becomes more sensitive. This paper investigates the impact of dynamic voltage support provided by fast fault current injection from the converter-based generation present in the transmission system, on a distribution system with a high share of RES during fault conditions. In addition, the impact of a hybrid synchronous condenser and battery system in the transmission network on the distribution system is also analyzed in this paper. The results show that fast fault current injection from converter-based generation and the hybrid system contributes to speedier voltage recovery of the distribution network. Such a faster recovery of the distribution system voltage can prevent the triggering of under-voltage protections for distributed energy resources, thereby increasing the system's robustness and resilience.
