Low-carbon economic dispatch of electricity-gas integrated energy system

In order to cope with environmental problems and improve energy efficiency, a joint operation mode of connecting carbon capture power plants and electric to gas conversion equipment is proposed with carbon storage equipment as the hub, taking the integrated energy system of electricity and gas as the research object. Firstly, the effects of carbon capture and electricity-to-gas joint operation mode on the consumption of new energy, the reduction of system carbon emissions and the improvement of the operating performance of each unit are analyzed, and a low-carbon economic dispatch model is constructed based on the low-carbon operation mechanism to achieve the low-carbon economic operation of the electricity-gas integrated energy system. The revised IEEE 39-node power network and the Belgian 20-node natural gas network coupling system verification shows that the proposed integrated electrical energy system operation mode can effectively promote wind power consumption and reduce carbon emissions.
