Abstract: This paper proposes a robustness and an optimum of the fuzzy logic-proportional
integral derivative (FLPID) controllers for automatic generation control (AGC) of a two
area interconnected hydro-thermal system and an application of bee algorithm (BA) in
order to design FLPID controllers. Traditionally, membership functions (MF) and
control rules (CR) of the fuzzy logic controller (FLC) were achieved by trial and error
methods of designers. To solve this problem, BA was proposed to concurrently tune
PID gains, MF and CR of the FLPID controllers to minimize frequency deviations and
tie-line power deviations of power system. Simulation results clearly showed that the
performance and the robustness of the optimal FLPID controllers were superior to the
conventional PID and the FLPID controllers in terms of settling time and overshoot.
