This paper presents the application of integral-proportional control with fuzzy tuning to the automatic generation control problem. Simulation results indicate that the control scheme is able to provide good performance in a single area as well as a two-area interconnected system with nonreheat or reheat turbines. Furthermore, it is shown that responses of the system employing the proposed controller are rather insensitive to parameter changes and speed governor deadband, with and without generation rate constraints. The control strategy depends only on area control error, requires low computational cost and is easy to implement.
