Source-load multi-time scale optimization scheduling method based on integrated energy system

The invention discloses a source-load multi-time scale optimization scheduling method based on an integrated energy system, which comprises the following steps: firstly, a source side considers that a thermal power generating unit is additionally provided with a carbon capture device to form a carbon capture power plant and renewable energy source coordination, and a load side considers various demand response resources to solve the operation limitation of the carbon capture power plant under multiple time scales; a day-ahead-intra-day two-stage low-carbon economic optimization dispatching model of source load coordination is constructed; secondly, dividing the demand response resources into first-level demand response resources and second-level demand response resources according to the response speed of different demand response resources to the power grid dispatching instruction; finally, an improved IEEE-39 node is used as an example for simulation, and the result shows that the provided scheduling method
