Abstract: For the short-process steel enterprises whose adjustable potential is closely related to their production process, a supplydemand interactive scheduling model considering the production process of such enterprises is proposed to motivate their enthusiasm to participate in grid scheduling and promote the consumption of renewable energy. Firstly, the resource-task network method is used to model the coupling relationship between each link of steel production and production resources, and the processing method of the connection relationship between the processes is improved to make the production operation plan more realistic and feasible. Secondly, considering the different interest of power grid dispatching and enterprise, a bi-level programming dispatching model is established to truly reflect the interactive game process between power supply and demand. Finally, in order to make the model solving process match the actual interaction process, a new heterogeneous decomposition algorithm is adopted based on the idea of hierarchical iteration to accelerate the convergence speed of the solution on the premise of ensuring that only real-time price and purchasing power are exchanged between two levels. The simulation results verify the effectiveness and superiority of the proposed improved method, and show that the proposed model can improve the ability of the system to absorb renewable energy while taking into account the interests of the enterprise.
