Focusing on the passive network, this paper analyzes the discrete mathematical model and its control strategy of the passive terminal of the VSC-HVDC system on the basis of the α-β frame of axes. The method of the functioning-fuzzy-subset inf

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
