Transient Stability Analysis on Modified IEEE 14-Bus System


Ermin Šunj, Ammar Arpadžić, Mirza Šarić


Power system stability represents an important condition of the safe and efficient operation of
the electric power system. This paper presents the transient stability analysis for the case of the new
generator grid connection. The analysis is performed on a modified IEEE 14-Bus test system. In total,
two cases were analysed. In the first case, the analysis with the maximum installed power of the generator
(250 MW) is carried out, while in the second case, the analysis is performed using the optimal generator
ratings (75 MW) using the DIgSILENT PowerFactory software. The transient stability analysis was
carried out under the three-phase symmetrical faults and the N-1 criterion requirements. The results
indicate that power system large disturbances significantly influence system operation and
characteristics. This paper demonstrates the importance of transient stability analysis, which is an
important part of power system studies and must be included in generator grid connection approval.
