This article presents the modelling and simulation results of the dynamic stability performance of a multiterminal VSC-HVDC system inside an ac network. The VSC is modelled as two decoupled sources; one fundamental frequency ac source and a dc current source. The VSC model developed was used in a HVDC grid test system and its response is shown. The results obtained indicate that the VSC modelling approach is consistent with the expected response of the system including VSCs.
