چکیده

در این مقاله با استفاده از الگوریتم تکاملی کلونی زنبور­های عسل (ABC) و براساس معیار انتگرال زمان-قدرمطلق خطا (ITAE) به طراحی کنترل­کننده فرکانس بار (LFC)در سیستم­های قدرت تجدید ساختار ­یافته با سیاست دوجانبه پرداخته شده است. در این راستا، در نظر گرفتن تابع هدف مناسب برای دست یافتن به عملکرد مقاوم مطلوب مهم است. نتایج شبیه­سازی­ها نشان می­دهد با بهره­گیری از معیار ITAE که با وجود انحراف فرکانس و خطای کنترل ناحیه (ACE) است، پارامترهای کنترل بهینه برای سیستم قدرت با استفاده از روش ABC به آسانی به­دست می­آیند. کارآیی روش پیشنهادی برروی یک سیستم قدرت چهار ناحیه­ای تجدید ساختار یافته با سناریوهای قراردادی ممکن تحت تقاضای بار زیاد و اغتشاش­های ناحیه­ای نشان داده شده است. با ارزیابی نتایج مشاهده می­شود که روش بهینه­سازی پیشنهادی در محدوده وسیعی از تغییرات پارامترهای سیستم و تغییرات بار در حضور خاصیت غیرخطی بودن سیستم، عملکرد مقاوم خوبی داشته، بنابراین، می­تواند در کنترل‌کننده­های دیگر نیز استفاده شود.

چکیده [English]

In this paper, a robust Artificial Bee Colony (ABC) algorithm based on Integral Time Absolute Error (ITAE) is proposed for solution of a Load Frequency Control (LFC) problem in a restructured power system that operates under deregulation according to a bilateral policy scheme. Precise tuning of the objective function is significant in achieving the desired level of robust performance in the proposed method. Simulation result suggests that optimal control parameters for power system can be designed with much less effort using ABC in which the objective function is chosen based on ITAE method on the frequency deviation and Area Control Error (ACE). The effectiveness of the proposed method is demonstrated on a four-area restructured power system with possible contracted scenarios under large load demand and area disturbances in comparison with conventional tuning of control parameters through ITAE performance indices. The evaluation results show that the proposed optimization strategy achieves good robust performance for a wide range of system parameters and load changes in the presence of system nonlinearities and is therefore superior to other controllers.
