“…In order to consider variations in parameters and the effect of wind shear, more advanced techniques, such as H ∞ control, are required. Robust control is applied to various control problems [8][9][10]. The H ∞ control characteristic can improve the stability of a system, because the response is considered positively in the frequency domain.…”

SUMMARYEffective utilization of renewable energies such as wind energy is expected instead of the fossil fuels. Wind energy is not constant and windmill output is proportional to the cube of wind speed, which causes fluctuating power of wind turbine generator (WTG). In order to reduce the fluctuating power of WTG, this paper presents an output power leveling technique of WTG by pitch angle control using H ∞ control, and the control input of WTG linear model is separated from the disturbance. The simulation results using actual detailed model for WTG show the effectiveness of the proposed method.

“…Therefore, the controller has good control and can improve the stability; this is seen in comparing the controller designed using a model whose multi-machine system is factorized to single-machine infinite-bus system and out of consideration of the influence of the inter-area oscillations, with the controller designed in consideration of the influence of the inter-area oscillations. Previous studies [13][14][15] have examined excitation decentralized controller for designed multi-machine power systems. To stabilize the entire electric power system, the state feedback controller is designed.…”

This paper proposes a robust decentralized controller based on optimal sequential design. The proposed controller can directly consider the inter-area oscillation mode on design phase. Further, the sequential procedure is applied to design for robust controllers in consideration of other controllers. The best design sequence of the controller is decided by using the condition number. The effectiveness of the proposed controller is demonstrated by comparing it with conventional controllers. Damping of many oscillations for a multi-machine power system is demonstrated through simulations, which considered a three line-to-ground fault for power system disturbance.

SUMMARYIn this paper, a systematic approach to design controllers based on H-infinity theory for a multimachine power system is presented. Generally, a centralized control scheme is difficult for a large-scale interconnected power system because of the necessity of obtaining information on the whole system, computation times, and so on. In order to handle these problems, two decentralized control schemes are proposed. One is based on the decomposition of information. The feedback gains for the whole system are obtained, and after decomposing the gains into subblocks for each area, the diagonal block is used to design the controller for each generator. The other is based on area decompositions. The procedure is carried out by decomposing the original system into blocks for each area and the local feedback gain is obtained by using information for each decomposed system. Furthermore, to improve the robustness of the system, an effective weighting matrix design, which involves the allocation of eigenvalues, is also proposed. Several simulation tests show the effectiveness of the proposed methods. ©
