Wind power output varies over time under the influence of meteorological conditions. Understanding these variations is indispensable to further wind power integration and effective operation of the power system in the near future. In this study, we developed time-series wind power output data of 9 power systems in Japan in the 2010 and the 2011 fiscal year for power supply-demand analysis. We analyzed the variations in time windows of 20 minutes or more. Furthermore, we evaluated the effects of output increasing rate restriction control. We found that the large variations can be absorbed by the small energy loss, and that this increasing rate restriction control is very effective against infrequent large variations.
