Author	Rehman, Bilawal Liu, Chongru
Abstract	Here, a novel approach is proposed to compute discrete value of converter tap position in AC/DC hybrid multi-infeed HVDC power flow solution. The approach is based on Newton–Raphson (NR) technique and sequential power flow method. An algorithm for the estimation of discrete tap position is devised by re-converging DC system to eliminate the error between discrete tap position and actual value of tap. The proposed technique computes new value of gamma for discrete value of tap which solves convergence problem of DC system caused by AC-voltage fluctuations. Theoretical bases and numerical results are presented to support new proposed approach. The technique is successfully applied to dual-infeed LCC HVDC feeding into the same AC system which is more practical scenario. The results validate the approach and show advantages in term of accuracy and convergence.
