Abstract
In this paper, to improve voltage stability of the most critical bus of the New England 39 bus test system has proposed a new DC transmission line based on the VSC-HVDC (Voltage source converter-High Voltage Direct Current) instead of AC transmission line. The power transferred has been provided by the VSC-HVDC that have two steady state control modes to the critical bus. It is determined by the sensitivity analysis the most critical bus of the power system. In this bus the effect of heavy loading on long term voltage stability is investigated. In the modified test system for all situations, to improve of the voltage stability is determined the best suitable control strategy for the voltage source converters. Simulations are conducted in DIgSILENT Power Factory 15.0 software. The results of proposed test system compared and presented the base system that included AC transmission line.
