With the gradual increase in the proportion of renewable energy generation such as wind power, it is necessary to implement low-carbon transformation of thermal power units and fully exploit the capacity of industrial load demand response, so as to achieve carbon peak and carbon neutralization of energy and power. On this basis, a multi-time scale scheduling method considering typical industrial load production processes is proposed in this paper. Firstly, with regard to the source, a comprehensive fexible operation mode of carbon capture power plants is introduced to coordinate with wind power. In the aspect of the load, the production characteristics of two typical industrial users are specifcally considered, and the production models that meet their specifc constraints are established. Secondly, the day-ahead and intra-day two-stage economic dispatch model of source–load coordination is constructed so as to optimize the production plan of typical industrial load and the output of units, while improving the problem of load loss and wind curtailment. Finally, an example analysis is carried out. The results show that the scheduling method proposed in this paper can make use of the scheduling advantages of source–load adjustable resources to realize the economic dispatch of power system.
