Abstract

In this paper, an efficient optimized fractional-order fuzzy proportional-integral-derivative controller (FOFPID) based on biogeography-based optimization (BBO) method is designed 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 15% and 43% reduction, respectively. Moreover, the simulation results were also demonstrate the effectiveness and the convergence of the BBO algorithm.
