Abstract

This paper presents an .efficient method for AC-DC power flow used in
non- synchronous intercoihection. The proposed method treats the converter
as voltage dependent loads and the variables are eliminated from the power
flow equations. The method is successfully implemented to IEEE 5-bus test
system interconnected with IEEE 14-bus test system. The technical
conditions for interconnecting power systems, the short circuit capacity of
AC connected b&, the geometrical topology of the land in DC link path, and
location of AC bus from the generating stations, are considercd.
