Abstract: The present work is about the load frequency control of a practical power system under certain operating conditions. The primary goal of the load frequency control is to reduce the area control error to zero when the system is experienced to abrupt load change. Real power is mainly affected by frequency change. To ensure satisfactory operation of the load quality of power delivered to load must be good so a load frequency controller is needed to ensure system frequency within the permissible limits. PID control is widely used in industry and accepted universally because they give robust performance under various operating conditions at least time compared to intelligent controllers. In this paper, dynamic PSO based Two-Degree- of Freedom Proportional-integral-Derivative (2- DOF PID) controller is used to tune the gains of the PID controller. Simulation results shows the advantage of this approach with respect to a PID controller.
