چکیده

In this paper , an efficient optimized fractional-order fuzzy proportional-integral-derivative controller (FOFPID) based on biogeography-based optimization (BBO) method is designd for automatic generation control of a two-zone four unit hydro-thermal power system. Studies were conducted in two scenarios . In the first scenario , the simulation was carryout for power system with pure-thermal units and in the second scenario; the simulation was performed for hydro-thermal power system . In each scenario , Ten percent load changes have occurred in both areas . Moreover , the simulations were also performed by applying the conventional PI , PID , and the hybrid PSO-PS based Fuzzy-PI controllers for two aforementioned scenarios . The numerical simulation results illustrated that the proposed optimized control scheme outperforms the other controllers such as the conventional PI , PID , and the hybrid PSO-PS based Fuzzy-PI controllers under uncertainties in terms of minimizing frequency deviations . Such that we had a decrease for the Integral Square Time Square Error (ISTSE) and settling time , with a ۱۵% and ۴۳% reduction , respectively . Moreover , the simulation results were also demonstrate the effectiveness and the convergence of the BBO algorithm .

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.
