This project is to provide the technology of power stabilization by using an energy storage system connected to a large scale wind farm. Field test will verify the effectiveness of energy storage to smoothing wind power and the effectiveness of control systems to operate the system. This project is funded by New Energy and Industrial Technology Development Organization (NEDO), a Japanese incorporated administrative agency, through the Electric Power Development Co., Ltd.

The basic aero-dynamical characteristics of twin blades in a wing-stroke motion was investigated utilizing the lifting-line theory.
A fundamental equation was prepared modifying the Waissinger's theory to be adaptive for the twin-blades in a wing-stroke motion, considering the geometrical condition according tothe free flow and the interactive interface of two blades.
The equation was solved numerically by Runge-Kutta method, equipped in the computer aided design tool named MATLAB & SIMULINK system.

The basic aero-dynamical characteristics of twin blades in a wing-stroke condition was investigated utilizing the lifting-line theory.
This supplemental note provides some result of parametric research according to the basic characteristics of the system.
Basic performance of flapping two blades, particularly the effect of aerodynamic interference each other was investigated thoroughly and it may provide some reference for designing the system of the new feature.

On the Power of a Wind Turbine with Fixed-Pitch Angle Wings for Sinusoidally Changing Wind Speed

We studied on output power of a wind turbine with fixed-pitch angle wings in variable-speed wind. A mathematical model of the wind turbine is given, and numerical simulation was done. In the model, we assumed that the torque coefficient was characterized by a tip speed ratio only. We showed thatthe displacement of the tip speed ratio from the optimum value, at which a wind turbine had maximum output power, due to aperiodic change of wind speed can be analyzed well by a characteristic frequency. The characteristic frequency is given by the inverse of the response time, which was derived in the former report. Output power of a wind turbine in variable-speed wind was given as a function of an averaged power coefficient and the variance of wind speed.
