Abstract

VSC-HVDC is anticipated as a flexible and reliable solution for photovoltaic (PV) power transmission. In this paper, the model of PV grid paralleled in infinite grid through VSC-HVDC is built in PSCAD/EMTDC. And corresponding D-Q decoupled control strategy for the system is proposed. Both normal condition and short-circuit fault condition have been simulated. The results show VSC-HVDC can improve recovery performance greatly.
