Research of control strategy for VSC-HVDC system under unbalanced grid voltage conditio

In view of problems of harmonic and power fluctuation of DC and AC side of VSC-HVDC system under unbalanced grid voltage condition, the paper used dual dq-PI control strategy with respective direction of positive and negative sequence components of grid voltage to inhibit the second harmonic of DC s...
