Shervin Samimian Tehrani, Peyman Salmanpour Bandaghiri

This paper presents the Simulation ofa14-bus system using STATCOM compensated by applying the error and see the impact of the voltage compensator buses. Voltage stability of a system is affected by reactive power limit of the system. FACTs devices improve the reactive power flow in system thereby improving voltage stability. This paper explores the effect of STATCOM on static voltage stability. IEEE-14 bus system has been used to demonstrate the ability of STATCOM in improving the voltage stability margin. These FACTs controllers help to increase the load ability margin of the power network. Modelling & simulation is performed using MATLAB SIM power system block set for evaluation.
