Power conditioner for stabilizing power disturbance caused of wind turbine generator system

In Japan, Feed in Tariff has started since July in 2012. Moreover only solar power is not attractive energy, a wind turbine generator is attractive energy from the point of view to reduce double carbon oxide emission. However, to connect the wind turbine generator system to the grid, the independent power producer (IPP) must compensate the power disturbance caused of the wind turbine. Thus, a power conditioner for stabilizing power disturbance is necessary. The authors have developed a new power conditioner using batteries in this paper. The control technique, specifications, circuit configuration and prototype test results are described.
