A New Model for Controlled Branch Impedance in Phasor-Based Transient Stability Programs

In transient stability (TS) studies, current injection models are widely used to present electrical power system elements. Such modelling causes divergence problems in some cases.

Description
Summary:In transient stability (TS) studies, current injection models are widely used to present electrical power system elements. Such modelling causes divergence problems in some cases. This paper presents a new current injection model to solve this problem. This new approach could be incorporated into a power system analysis course at either undergraduate or postgraduate level to expand students' understanding of problems that may arise in TS studies. Finally, simulation results of a power system obtained by the proposed model are compared to those obtained by Simulink to show the effectiveness of the new approach.
