Abstract: The automatic load frequency control problem has been addressed in different power system areas such as single area, two area and three areas. Each area contain one thermal unit, one hydro unit and one gas unit. Initially, single-area three-unit system is addressed to analyze without and with PID controller for 10% of step load perturbation. After that, a two-area six-unit and three area-nine-unit systems are acknowledged and analyzed the effectiveness of PID controller. At last, capability of the proposed controller is assessed with a random step load disturbance. The total study was taken up in MATLAB/SIMULINK environment.
