Abstract

Based on the technology of carbon capture and power to gas （P2G）, a day-ahead dispatching model of power-gas integrated energy system considering zero-carbon emissions is established in this paper. First, a framework of zero-carbon electric-gas integrated energy system is established. The CO₂ generated by coal-fired units is collected by the carbon capture devices, and the captured CO₂ is converted into CH₄ by P2G technology. Meanwhile, the mathematical relationship between the output of thermal power unit and the amount of CH₄ is deeply studied. Then, a dispatching model is established to minimize the comprehensive operation cost. At the same time, to achieve the goal of zero-carbon in the electric-gas integrated energy system, the CO₂ that cannot be collected and utilized is discharged into the atmosphere by purchasing carbon emission rights, so as to achieve the goal of zero-carbon. Finally, an example is given to verify that the proposed model can achieve the goal of zero-carbon in electric-gas integrated energy system. Meanwhile, compared with the traditional dispatching model, the wind curtailment is reduced by 1320.96 MWh and the operating cost is reduced by 561.6 thousand yuan.
