description	The invention discloses an energy storage stabilizing method and system based on a grid-connected power cross-time scale fluctuation index. A first time period and a second time period are set according to a grid-connected point power fluctuation index; obtaining the maximum value and the minimum value of the grid-connected point power in each time period; setting a power fluctuation limit value in each time period; determining the fluctuation range of the active power of the grid-connected point in each time period based on the corresponding power fluctuation limit value by using the maximum value and the minimum value of the power of the grid-connected point in each time period and the occurrence time sequence of the maximum value and the minimum value; according to the membership relationship of the fluctuation range of the active power of the grid-connected point in each time period, based on the actual power of the new energy station, determining an optimal value of the energy storage active power; corre
