All national power system networks are multi-area networks interconnected by tie-lines. Automatic Generation Control (AGC) ensures the frequency and tie-line power errors are zero in the steady state so that nominal frequency and tie-line schedules are maintained. This can be achieved by sophisticated controllers. In this paper a three area power system is considered. The three areas consists of non reheat turbine thermal generator, reheat turbine thermal generator and hydro generator respectively. A control technique based on Active Disturbance Rejection Control (ADRC) is employed for this purpose. The resulting system is simulated using MATLAB Simulink software. The performance of ADRC is compared with classic PID Controller tuned by Zeigler-Nichols method. The outcome of ADRC is very good with low overshoots and minimum settling times.
