Zusammenfassung:	To provide a method for controlling charging and discharging of a storage battery, starting and stopping of a water electrolysis apparatus and starting and stopping of an engine generator, directed at a renewable energy power generator including a wind turbine generator in which a generated power varies with a weather condition.SOLUTION: In the power fluctuation relaxation method for an engine generator 6 generating electric power using stored hydrogen and a wind power generating system S using a storage battery 3, at least one type is available as a threshold value of the storage capacity of a hydrogen tank 5 and at least two types are available as a threshold value of the storage capacity of the storage battery 3, respectively; therefore, charging and discharging of the storage battery 3, starting or stopping of a water electrolysis apparatus 4 and starting or stopping of the engine generator 6 are controlled, respectively, according to a relationship between the respective threshold values, the storage capacity of the hydrogen tank 5 and the storage capacity of the storage battery 3.SELECTED DRAWING: Figure 1 【課題】気象条件によって発電電力が変動する風力発電装置を含む再生可能エネルギ発電装置を対象に、蓄電池の充放電、水電電解装置の起動停止、エンジン発電機の起動停止を制御する方法を提供する。【解決手段】貯蔵した水素を用いて発電するエンジン発電機６と蓄電池３を用いた風力発電システムＳの電力変動緩和方法として、水素タンク５の貯蔵量の閾値として少なくても１種を、蓄電池３の貯蔵量の閾値として少なくても２種を設けることにより、それら各閾値と、水素タンク５の貯蔵量および蓄電池３の貯蔵量の関係によって、蓄電池３の充放電と、水電解槽装置４の起動または停止と、エンジン発電機６の起動または停止をそれぞれ制御することとした。【選択図】図１
