Multi-time scale scheduling method for integrated energy system

The invention relates to the technical field of energy systems, in particular to a multi-time-scale scheduling method for an integrated energy system, which is characterized by comprising the following steps of: firstly, constructing models of a distributed energy unit, a carbon capture system and power-to-gas equipment and constraint conditions of the models; secondly, taking the minimum operating cost and the minimum carbon emission cost as targets, considering day-ahead scheduling and intra-day rolling scheduling, and establishing a multi-target optimization scheduling model of the integrated energy system; and finally, obtaining operation parameters of the integrated energy system, solving an optimal solution of the integrated energy system optimization scheduling model by using an algorithm under constraint conditions, and performing multi-energy complementary scheduling on the integrated energy system by taking the optimal solution as a scheduling scheme. According to the method, economical efficiency a
