要約(英語): This paper presents a new control method of wind turbines group by use of a dynamic control including Pump-Up Operation. Under a condition of oscillating wind below the rated speed of the wind turbine, Maximum Power Point Tracking (MPPT) operation is a key to improve its efficiency. Even though, owing to the huge inertia of the wind turbine, the operating point of the wind turbine yields to the unavoidable delay to the Maximum Power Point. By use of the dynamic control, wind turbines respond to the wind speed change more rapidly. The wind turbines hence reach the Maximum Power Point rapidly and capture the energy from the wind more efficiently. On the other hand, because of the dynamic operation, the output from a wind turbine fluctuates more severe than that of the normal operation. In the proposed solution, by taking advantage of the kinematic energy stored in other wind turbines which belong to the same windfarm, not only the efficiency of output power, but also the severity of the fluctuation is improved. In the result of some simulation, group dynamic operation enables wind famrs to improve its efficiency and smooth the fluctuation of the output from the windfarm.
