Abstract

FACTS devices are a new technology that developed in recent years and has been used vastly in modern power electrical networks. These devices can improve the voltage profile and reduce the active power loss in large scale power networks. These devices can inject or absorb variable reactive power. The level of this injected or absorbed reactive power must be controlled to have normal and good conditions in the power network. PID controllers are a very popular and efficient controller that has a simple structure. In this paper application of the UPFC unit in a power network is proposed to enhance the voltage profile and reduce the power loss. In order to have good condition and performance, the manner of UPFC must be controlled. In the proposed method PID controller is proposed to control the UPFC. In the PID controller, the free parameters have a vital role in its performance. Therefore in this study, ICA is used to find the optimum value of these parameters. The imperialist competitive algorithm (ICA) is one of the best and rapid nature-based optimization algorithms that its capabilities are proven in literature. The proposed system is tested real standard system and the obtained computer simulation results show that the proposed method has excellent performance.
