The invention discloses a power system peak regulation method and device for energy storage capacity optimal configuration. The method comprises the following steps: obtaining a detection voltage value and a detection frequency value of a connection point of an energy storage system and a power distribution network; respectively calculating a first difference value between the detection voltage value of the connection point and the voltage value of the power distribution network bus and a second difference value between the detection frequency value of the connection point and the frequency value of the power distribution network bus; calculating a power deviation value output by the energy storage system based on the first difference value and the second difference value; and adjusting the output power of the energy storage system through droop control based on the power deviation value to realize peak regulation of the power distribution network. The power of the energy storage system is controlled from the
