Under the “dual-carbon” background, in order to realize low-carbon emission and maximize wind power consumption of the microgrid system, an optimal scheduling strategy with a two-layer model of integrated energy system (IES) containing carbon capture power plant (CCPP) and power-to-gas (P2G) coupling and vehicle into the grid (V2G) is proposed. Firstly, at the low-carbon technology level, to address the problem that the CCPP and P2G equipment operate out of sync in time, a liquid storage tank is added as a CO₂ buffer station in the middle of the CCPP and the P2G equipment, and a mathematical model containing the CCPP, the P2G equipment and the gas turbine is established. Moreover, a laddered carbon transaction is established to impose low-carbon emission constraints on the IES. Secondly, in order to fully utilize the dual characteristics of EV load and energy storage, strategies are formulated to guide EV charging and discharging during wind abandonment hours and peak hours of the IES to carry out energy time shifting. Finally, at the level of economic efficiency, the integrated operating cost minimization is taken as the objective function, and MATLAB is used to invoke the GUROBI solver to solve the problem. By setting up different scenarios for comparison, the results show that the scheduling strategy can improve the level of microgrid wind power consumption while realizing the low-carbon economic operation of the system.
