Under the background of“double carbon”

in order to optimize the structure of energy

improve the consumption of renewable energy and promote the carbon emission reduction of the integrated energy system（IES）

a low- carbon economic dispatch mode based on carbon capture and electro- hydrogen- gas two-way conversion is proposed. Firstly

the two-stage process of power to gas coupled with hydrogen storage

hydrogen fuel cell and carbon capture is analyzed. The energy flow model of the IES with clean energy as the main energy supply and the electricity

heat

cold and gas load as the end is constructed. Then

the carbon cost of each equipment is analyzed for its participation in the carbon trading market. Finally

a mathematical model of low-carbon economic operation with the minimum operation and maintenance cost

energy purchase costs

environmental costs and hydrogen sales benefits is constructed. Considering the equipment constraints and the energy balance constraints of the system

the different typical operating modes are analyzed and compared

and the consumption character istics

environmental protection and economy of the proposed scheduling model are verified.
