Power grid frequency modulation method based on cooperation of submerged arc furnace and polycrystalline silicon in industrial park

Abstract

The invention discloses a power grid frequency modulation method based on cooperative cooperation of a submerged arc furnace and polycrystalline silicon in an industrial park, solves the problem that the frequency modulation capacity is limited when the submerged arc furnace and the polycrystalline silicon separately participate in the response of a power grid demand side, and realizes the cooperative cooperation of the submerged arc furnace and the polycrystalline silicon to stabilize the power fluctuation of a power grid. Based on the actual production boundary constraint of the submerged arc furnace and the polycrystalline silicon, the frequency modulation capacity of the submerged arc furnace and the polycrystalline silicon in a certain production state is determined, the frequency modulation capacity of the submerged arc furnace and the polycrystalline silicon serves as the distribution principle, power values needing to be adjusted respectively under large disturbance are determined, and collaborative stabilization of power fluctuation of a power grid is achieved. The submerged arc furnace and the polycrystalline silicon cooperatively participate in power grid interactive response, the adjustable capacity of the load side is greatly increased, and meanwhile the output pressure of the generator side is relieved.

Description

technical field [0001] The invention relates to the technical field of demand-side management of industrial loads, in particular to a power grid frequency regulation method based on the coordinated cooperation of submerged arc furnaces and polysilicon in industrial parks. 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. High-energy-consuming industrial loads such as electrolysis and arc 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. Industrial loads with large capacity and high energy consumption can participate in peak regulation and frequency reg...
