Compared with the existed PID methods for the multi-area LFC system, the proposed method has two advantages, which are the decoupling of total tie-line power flow and the robust disturbance rejection. Finally the proposed method is simulated with and without reheated turbine in the environment of Matlab/Simulink to validate the advantages and robustness of proposed method.
