Fractional order PID controller design for LFC in electric power systems using imperialist competitive algorithm

(in lingua inglese)

In this paper, an FOPID controller was proposed for LFC in a three-area power system. The parameters of controllers were tuned using ICA. Simulation of comparative cases confirmed that the proposed controller had better performance in LFC of the interconnected power system. Responses of the power system to disturbances were much smoother and less oscillatory using the proposed controllers. In most cases, the settling time and maximum deviation of power system responses diminished when FOPID controllers were implemented.
