Control scheme of hybrid wind-diesel power generation has been proposed in this work. This work focus on frequency control using robust controllers such as Pitch controller and SMES. The robust controllers were designed based on inverse additive perturbation in an isolated hybrid wind - diesel power system. The performance and stability conditions of inverse additive perturbation technique have been applied as the objective function in the optimization problem. The GA has been used to tune the control parameters of controllers. The designed controllers are based on the conventional 1st-order lead-lag compensator. Accordingly, it is easy to implement in real systems. The damping effects and robustness of the proposed controllers have been evaluated in the isolated hybrid wind - diesel power system. Simulation results confirm that the robustness of the proposed controllers are much superior to that of the conventional controllers against various uncertainties.
