Abstract:
In this study, optimal control of voltage source converter- high voltage direct current (VSCHVDC) transmission systems is modeled and its performance in weak networks is compared with strong systems. The comparison is made considering how they track the desired values of DC voltage and AC current while switching or fault occurs, which determines the system stability. A proportional-integral controller with decoupled control variables of a typical generator-load VSC-HVDC system is proposed for optimal control. Simulation results show that a fault caused by switching in weaker networks, of which the short circuit level is lower rather than stable networks, leads to higher changes in DC voltage and AC current.
