The invention discloses an energy storage station capacity and charge-discharge power configuring method adaptive to peak clipping and valley filling and relates to the field of intelligent distribution network planning. The method is applicable particularly before investment and construction of an energy storage station during distribution network planning to determine the capacity and charge-discharge power of the energy storage station. A typical load characteristic curve of an area to construct an energy storage station is acquired through the power department, charge-discharge state of the energy storage station at each moment is determined according to its average load powder, and charge-discharge power that the energy storage station should have currently is acquired by calculating according to charge-discharge capacity balance rules. By using the method, it is possible to calculate reasonable capacity and charge-discharge power of the energy storage station before investment and construction of the energy storage station, the subjective factor, artificial intervention, in the planning and construction process is avoided, the configuring method of the invention provide certain peak clipping and valley filling effect after the investment and construction of the distribution network energy storage station.
