The power fluctuations of the wind power generation due to the wind speed variation cause a considerable frequency deviation to the power system in Tohoku and Hokkaido, etc. The frequency deviation has hardly an allowance. It is necessary to smooth the power fluctuations to interconnect a new wind power generation to the power system in those areas. Thus, the power storage system such as the battery system must be installed together with wind power generation. It needs the inverter system because there is DC power supply in the battery system. However, the system is expensive. A recent wind power generation has inverter system. The smoothing performance for wind power fluctuations can be given to the wind power generation by using the inverter system.The paper proposes a new wind power generation for which the smoothing performance is provided by such a scheme. The smoothing performance is examined in using simulation software PSCAD/EMTDC. The simulation result shows that a new wind power generation has an excellent smoothing performance for wind power fluctuations.
