Abstract

In this paper, a novel optimal reactive power flow solution approach in
multi-terminal HVDC (High Voltage Direct Current) systems is studied. ULTCs’
(under load tap changer transformers) full equivalent model for the DC
converters’ are taken into account in the proposed AC-DC power unlike the
similar studies in the literature. Thus, the proposed study provides real
accurate results for practical AC-DC applications. Optimal reactive power flow
for minimum active power loss is provided by Genetic Algorithm (GA). For the
test of the proposed study, the IEEE 14-bus test system modified to AC-DC
system is used in the study. The obtained test results prove that the proposed GA
based optimization method is effective to reach the global optimum point of
minimum active power loss without dropping to local minimum point through
satisfying system constraints.
