Under the ‘dual-carbon' goal,industrial parks,as the most important and extensive carriers of industrial systems,must undergo low-carbon transformation. In this context,this paper establishes a bi-level optimal dispatching model of low-carbon industrial park considering flexible scheduling of high-energy-consuming enterprises' production workshops. The model fully exploits the flexible adjustment ability of high-energy-consuming enterprises,obtains the optimal low-carbon scheduling plan of the park by flexibly adjusting the production scheme of high-energy-consuming enterprises to realize the coordinated operation of the industrial park and high-energy-consuming enterprises. Firstly,the upper layer establishes an optimal scheduling model with the objective of minimizing the total operating cost,taking into account carbon trading and tradable green certificate costs. Then,the lower layer focuses on the flexible scheduling problem of the high-energy-consuming enterprise's production workshops within the industrial park,aiming to minimize the maximum completion time and cost. The cost savings achieved by enterprise scheduling at the operational layer are used as subsidies. The upper and lower layers continuously coordinate and schedule plans to achieve the optimal objective. Finally,the feasibility and effectiveness of the proposed model are verified through case studies. The proposed approach not only reduces production costs and improves production efficiency but also effectively promotes load balancing,realizing the low-carbon operation of the industrial park.
