Heat supply system layered optimization scheduling method considering demand response and supply-demand interaction

The invention discloses a heat supply system layered optimization scheduling method considering demand response and supply-demand interaction. The method comprises the following steps: carrying out load prediction on a demand side in each day-ahead scheduling time period; establishing a system demand response model, making a thermal load response plan, sending a response demand to a demand side, and exciting a user to participate in response; building a demand side heat utilization building portrait; correcting the initial heat demand of the demand side; on the basis of the corrected heat demands of the different heat utilization buildings on the demand side, the maximum economic compensation on the demand side serves as a target function, a demand side optimization scheduling model is established, and heat supply regulation and control parameters of the different heat utilization buildings in all scheduling periods of the next day are decided and issued to the demand side to be executed; and on the basis of
