DETERMINATION OF TRANSMISSION TRANSFER CAPABILITY WITH SECURITY AND VOLATAGE STABILITY

There has been an increased interest in quantifying the transmission transfer capability of power systems. Transfer capability indicates how much a particular bulk power transfer can be changed without compromising system security under a specific set of operating constraints and voltage stability capturing various contingencies. Hence this paper will touch on the security-constrained optimal power flow and P-V methodology for providing insight into the secure limit of interface flow between areas and steady-state voltage stability. An attempt to cover as much of the field as possible has been made by quoting tests on 2003 Korean electric power system.
