Abstract :
A new robust power oscillation damper (POD) design for a doubly fed induction generator based-wind turbine is proposed in this paper. The POD structure is specified by the second-order lead/lag compensator with single input signal. The parameters optimization of POD is formulated based on a mixed H2/H∞ control using linear matrix inequalities. The POD parameters are optimized by the firefly algorithm so that the damping performance against system disturbances and the robustness under system uncertainties are satisfied. Simulation results in a single machine infinite bus confirm the superior robustness of the proposed POD over the conventional POD.
