The development of an integrated energy system is a key initiative to economic development

energy conservation and emission reduction. Firstly

to improve the peaking capacity of the units and reduce CO2 emissions

carbon capture technology is introduced into the integrated energy system

and its role in the flexibility

economic

and low-carbon operation of the integrated energy system is studied.Then

to reduce the pressure on the system caused by fluctuations in load and wind power peaks and valleys

the role of demand response of electric and thermal loads is considered to achieve healthy and sustainable operation of the integrated energy system. Finally

the role of energy coordination and coupling is considered

and a low-carbon economic dispatch model for the integrated electricity-thermal energy system is constructed to minimize the comprehensive cost. The results of the analysis show that the combined effect of carbon capture and demand response reduces the total operating cost and carbon emission cost of the system

promotes the consumption of wind power from both the source and load sides

and facilitates the flexible dispatch and low carbon operation of the integrated electricity-thermal energy system.
