With the high proportion of renewable energy connected to the grid, it brings many new challenges to the flexible regulation and power balance of the power system. Typical industrial loads have complete infrastructure and large individual user capacities, allowing them to participate in power balance adjustment through demand response mobilization and fully tapping into their own regulation potential. This article selects aluminum electrolysis load as the research object. Firstly, based on the analysis of the aluminum electrolysis industry process, key electricity-consuming equipment is identified, and the potential of demand response for these devices is analyzed. Then, an aluminum electrolysis enterprise demand response model that takes into account adjustment costs is constructed with the optimization objective of minimizing operating costs. Finally, based on actual electricity consumption data from a power grid and an aluminum plant, the demand response potential of aluminum electrolysis is evaluated using the established demand response model to verify its effectiveness. The model established in this article can fully consider the balance between production safety and adjustment benefits of the enterprise, quantitatively evaluate the demand response potential of aluminum electrolysis load under given incentive intensity, and provide reference for power grid companies to evaluate the demand response potential of industrial users and formulate dispatching plans and incentive prices.
