Abstract
This paper presents a new approach to perform time simulation of power system transient stability using implicit quadratic integral method. Fast and reliable simulation of the transient stability is required to achieve high reliability based on the on-line stability assessment. The trapezoidal method has been mainly adopted for this purpose. However, the proposed method shows the possibility of improvement in accuracy with no loss of the computation speed. The proposed method is tested with some typical case of ‘stiffness problem’ and for transient stability analysis in power systems.
