A new robust PID load frequency controller

A new systematic tuning method with a new structure to design a robust PID load frequency controller for multimachine power systems is presented. The control strategy is mainly based on a maximum peak resonance specification that is graphically supported by the Nichols chart. The proposed controller design is straightforward and effective. It also guarantees that the overall system performance is desirable. Comparative results of this new load frequency controller and a conventional PI one for a multimachine power system example show its robustness with a satisfactory response when the parameters of the system change.
