Abstract

Unified power flow controller (UPFC) is one of the most important flexible AC transmission systems (FACTS) devices in power systems. It has many applications such as stability enhancement, power flow control, voltage support, etc. In this paper UPFC is used in order to control voltage. In this scope, UPFC is installed on a specified bus and the voltage of the proposed bus is controlled by using UPFC. In order to optimize performance, the parameters of UPFC controllers are tuned using genetic algorithms (GA) optimization method. Simulation results, which are carried out on a multi-machine electric power system, clearly show effectiveness and viability of UPFC in voltage control.

 

Key words: Unified power flow controller, voltage Support, dynamic stability enhancement, multi-machine electric power system genetic algorithms.
