Damping of oscillations of the IEEE 14 bus power system by SVC with STATCOM

Flexible AC Transmission Systems (FACTS) Controllers are used to increase transmission capacity by damping the power system oscillations and regulating the bus voltage at which the Static Compensator is connected. The focus in this paper is to describe the use of SVC with STATCOM Controllers and compare them in static voltage stability improvements for the damping of the IEEE 14 Bus power system oscillations. A Single line diagram of the IEEE 14 Bus standard system is used in this paper with load assumed to be represented by constant impedance. The size and installation location for load margin improvement and price discussions are addressed. The Static VAR Compensator device is used to improve the voltage and reactive power condition in power systems network. The IEEE 14 Bus is modeled using the elements of Simulink. The effectiveness of the proposed controllers, the improvements in power quality and in voltage profile are demonstrated. In the simulation, the results of the proposed model for the SVC and STATCOM Controllers are determined. Then, they are compared with results obtained from the SVC with the conventional PID Controller.
