Abstract:
The present technological developments in power electronics industry increase the utilization of various types of Flexible AC Transmission Systems (FACTS) controllers. Depending on the type of converters connection, there are single and multi-line FACTS controllers. Based on the type of connection, amount of the compensation and the advantage of convertible static compensators (CSC), Generalized Unified Power Flow Controller (GUPFC) is presented in this paper. Voltage source based power injection model of GUPFC is used to incorporate this device in Newton Raphson load flow solution, to analyze the effect of this device on system parameters. The proposed methodology is tested on standard IEEE-5 bus and IEEE-14 bus test systems with supporting numerical and graphical results.
