The invention provides an electric power system frequency modulation method and device, a control system, electronic equipment and a medium, and the method comprises the steps: collecting the required power of an electric vehicle in a charging state corresponding to each charging cabinet, the charging current of each charging cabinet, and the power grid voltage of an electric power system, and carrying out the frequency modulation of the electric power system based on the charging current and the power grid voltage of each charging cabinet; determining the charging power input by the corresponding charging cabinet, and determining the current power grid frequency of the power system based on the power grid voltage; obtaining power after frequency modulation according to a preset frequency modulation strategy; and adopting the charging power of each charging cabinet to correct the power after frequency modulation to obtain charging set power, performing power distribution on the charging set power according to a preset power distribution rule, and then sending the distributed charging set power to each charging cabinet so as to modulate the charging power output by each charging cabinet. According to the method, stable adjustment of the frequency of the power system is supported in the charging process.
