Abstract :
Different control schemes adopted in a multi-terminal VSC HVDC (MTDC) system will change the power injections into the connected AC grid and thus affect its dynamic performance. This paper investigates a multi-machine AC system model integrating a 4 terminal VSC HVDC system for wind farm connection and onshore power sharing. A series of control strategies are created for the MTDC grid including voltage margin control and different droop control settings. The DC system power sharing and the corresponding effects on the AC system are mainly considered. This work is carried out in DIgSILENT PowerFactory using case study simulations of the integrated system model.
