The invention discloses an energy storage power station time period electric quantity rolling control method adapting to peak regulation and frequency modulation of a power grid. The method is appliedto scheduling control requirements of power grid side large-scale energy storage in power grid peak regulation and frequency modulation multi-application scenarios. A typical time period of an energystorage power station is predefined through peak regulation requirements, an operation control behavior of the energy storage power station in a defined period of time within one day is appointed; atime period electric quantity rolling calculation result is taken as base point power of an active control target of the energy storage power station, on the basis, the adjustment of the unbalanced power of the power grid is participated, base point power self-adaptive correction of the predefined time period is achieved, it is ensured that the SOC of the energy storage power station is controlledin place before all the time periods are finished, the control targets of peak regulation and frequency modulation of a power grid can be considered, enough adjustable electricity consumption space is reserved for the energy storage power station, and therefore, the economic benefits and the energy utilization efficiency of the energy storage power station are improved. Compared with a plan tracking mode, the SOC control accuracy of the energy storage power station is improved by 40% after the method is adopted.
