چکیده

FACTS devices are new technology that developed in recent years and have 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 power network. PID controllers are very popular and efficient controller that has simple structure. In this paper application of UPFC unit in 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 PID controller the free parameters have 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 many literatures. The proposed system is tested real standard system and the obtained computer simulation results show that the proposed method has excellent performance.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
