Description: This
paper proposes an optimal control strategy for an HVdc light system
using a direct current vector control mechanism. The proposed
approach is compared with the traditional vector control
method for different HVdc control requirements, such as active
power, reactive power, and grid voltage support control. A limitation
of the conventional control mechanism is analyzed through
a theoretical study and computer simulation. Closed-loop control
evaluation demonstrates that the proposed approach works well
for HVdc light system control both within and beyond the physical
constraints of the system, such as rated power and saturation of
pulse width modulation (PWM).
