The invention relates to the technical field of industrial load demand side management, particularly provides a frequency modulation capacity determination method and device for cooperative cooperation of a submerged arc furnace and energy storage, and aims to solve the technical problem that the submerged arc furnace and an industrial park energy storage device cooperatively participate in power grid frequency modulation response. The method comprises the steps of determining adjustable capacity of the energy storage device based on charging and discharging power of the energy storage device; determining the adjustable capacity of the submerged arc furnace based on the active power of the submerged arc furnace and the minimum active power limit in the smelting stage; and determining the adjusting power of the submerged arc furnace and the adjusting power of the energy storage device when the submerged arc furnace and the energy storage device cooperatively participate in the frequency modulation response of the power grid by utilizing the adjustable capacity of the energy storage device, the adjustable capacity of the submerged arc furnace and the power of the industrial load participating in the frequency modulation response of the power grid. The scheme can increase the adjustable capacity of the load side, reduce the pressure of the generator side, realize source-grid load-storage coordination and ensure the safety and stability of the power grid.
Description
technical field [0001] The invention relates to the field of demand-side management of industrial loads, in particular to a method and device for determining a frequency modulation capacity in cooperation with submerged arc furnaces and energy storage. Background technique [0002] With the expansion of the scale of the power grid, the access of a high proportion of new energy sources and the increasing load, the problems of peak regulation and frequency regulation and frequency stability of the power grid are becoming more and more serious. Arc-type high-energy-consuming industrial loads have the characteristics of high power consumption and stable power, and have huge potential for power regulation. Adjusting the power of industrial loads in a short period of time will not seriously affect industrial production. Therefore, large-capacity, high-energy-consuming industrial loads can participate in power grid peak regulation and frequency regulation. [0003] Under normal ci...
