AB  - Problem statement: The disturbance in power system is unavoidable situation. It cause in
voltage sag in power system. Approach: This study applied the STATCOM to mitigate voltage of the
system. The mathematical model of power system equipped with a STATCOM is systematically
derived. The presented mathematical model is shown how it effects on voltage sag improvement. The
simulation results are tested on a Single Machine Infinite bus. The proposed method is equipped in
sample system with severe disturbance. The variation voltage of the system without and with a
STATCOM is plotted and compared. Results: It was found that the system without a STATCOM has
high voltage variation especially voltage sags whereas with a STATCOM the system voltage has
small voltage sages. Conclusion: From the simulation results, the STATCOM can mitigate voltage
of power system.
