Abstract :
The paper describes a new method for determining critical load for a bus with respect to its voltage collapse limit of an interconnected multi-bus power system. For this purpose, network partitioning technique is used to transform load flow Jocobian matrix into a two by two matrix with respect to a selected/target bus and a procedure has been developed to determine load margin of the target bus using the elements of the transformed two by two elements Jacobian matrix and the bus voltage of the target bus. The validity of the proposed method has been investigated for the IEEE 30 and IEEE 118 bus systems.
