A hybrid fuzzy-PI controller for voltage source
converter based HVDC (VSC-HVDC) transmission system is
proposed in this paper. At first, the elementary model of VSCHVDC
is described. Then the fuzzy self-tuning control strategy is
proposed, in which direct current control strategy and dual
closed loop structure are designed in dq synchronous reference
frame. Independent control of the active and reactive power is
realized. Simulation results show that the designed control system
obtains satisfying performance, and the adjustments of power
flow could be achieved quicker than convention PI control.
