提高清洁能源利用率，降低能源系统碳排放是实现能源结构低碳化转型以及“双碳”目标的重要手段。基于此背景，提出了一种阶梯式碳交易机制下包含风电、电储能、燃气机组、碳捕集设备与含储热光热电站的综合能源系统低碳经济调度方法，并结合负荷侧柔性资源的响应策略，从源荷两端联合调度挖掘综合能源系统在经济运行与低碳环保方面的调度潜力。最后以系统运行总成本最小为优化目标，运用CPLEX商业求解器对多个场景进行求解，结果表明：所提源荷协调调度方法可以有效降低系统碳排放并提高系统运行效益。

Improving the utilization rate of clean energy and reducing the carbon emissions of energy systems are important means to achieve the low-carbon transformation of energy structure and the goal of "double carbon". Based on this background, a low-carbon economic dispatching method of integrated energy system including wind power, electric energy storage, gas turbine, carbon capture equipment and thermal storage solar power station under the step-by-step carbon trading mechanism was proposed. Combined with the response strategy of flexible resources on the load side, the dispatching potential of integrated energy system in economic operation and low-carbon environmental protection was explored from the joint dispatching of source and load. Finally, with the minimum total cost of system operation as the optimization objective, CPLEX commercial solver was used to solve multiple scenarios. The results show that the source-load coordinated scheduling method proposed can effectively reduce the system carbon emissions and improve the system operation efficiency.
