Optimal Settings of BTB-VSC in Interconnected Power System Using TFWO

This paper presents optimal settings of the Back To Back Voltage Source Converters (BTB-VSC) for optimal operation of a power system. The optimization is applied to achieve three objectives which are minimum total power losses, minimum line loading deviation and minimum voltage deviation. The optimization process is applied using Turbulent Flow of Water based Optimization (TFWO) algorithm. The study is applied to the IEEE 68-bus system which is connecting the New England system and New York system. Three scenarios are considered to connect the New York system with New England system using BTB-VSC in comparison with AC lines. The simulation and optimization process are performed using DIgSIENT power factory software application.
