要約(日本語): This paper presents the application of robust SMES controller for stabilization of power system oscillations in an interconnected power system attached with wind farms. However, wind power is frequently changed and unpredictable. High penetration of wind power adversely affects power system operations, and may lead to severe problems such low frequency. To cope with the problem, robust SMES controller is designed and utilized to improve the system damping performance and robustness against system uncertainties. In particular, the control design problem is formulated as an optimization problem and is solved by a heuristic algorithm to automatically obtain the controller parameters. The objective function considers both the damping performance index and the robust stability index. Moreover, scalar uncertainty models are included in a system. Consequently, simulation results and evaluations are carried out to illustrate the effectiveness and robustness of the proposed control scheme.
