摘　　要：面对日益凸显的能源危机以及全球变暖等问题,构建低碳清洁、安全高效的能源供应系统是改善环境污染和实现“碳达峰、碳中和”目标的重要途径之一。提出了一种面向综合能源系统的多能减碳装置最优配置的多目标优化模型,首先对多能减碳装置进行减碳特性建模,并提出系统加权平均碳势概念,通过区域综合能源系统碳流计算得到反映各能源子系统碳排放强度的支路碳流率,采用支路碳流率的占比作为各子系统的平均碳势权重,系统加权平均碳势克服了各子系统之间负荷节点数目和量级不对等的缺陷,可以合理表征系统整体碳排放水平,避免优化过程中只选择单一子系统的极端境况;然后以经济性成本最低和系统加权平均碳势最小作为目标函数,建立多目标最优配置模型,采用NSGA-Ⅱ算法求解最优多能减碳装置建设方案与成本;最后采用综合能源系统测试算例进行验证,算例根据加权平均碳势的变化得到不同减碳效果下的多能减碳装置最优配置与成本,以及各装置减碳量与全域总减碳量,验证所提减碳方法的合理性。验证结果表明,提出的系统加权平均碳势的概念,可作为一种减碳灵敏度指标,引导每一个能源子系统公平合理地参与减碳优化过程。In the face of the increasingly prominent energy crisis and global warming,building a low-carbon,clean,safe and efficient energy supply system is one of the important ways to improve environmental pollution and achieve the goal of“carbon peak,carbon neutrality”.This paper proposes a multiobjective optimization model for the optimal allocation of multi-energy carbon reduction devices for integrated energy systems.Firstly,the carbon reduction characteristics of multienergy carbon reduction devices are modeled,and the concept of system weighted average carbon potential is proposed.Using the proportion of branch carbon flow rate as the average carbon potential weight of each subsystem,the system’s weighted average carbon potential overcomes the defect of unequal number and magnitude of load nodes among subsystems,and can reasonably characterize the overall carbon emission level of the system,avoiding the extreme situation of selecting only a single subsystem in the optimization process.Then,taking the lowest economic cost and the lowest weighted average carbon potential of the system as the objective function,a multi-objective optimal configuration model is established,and NSGA-Ⅱalgorithm is used to solve the construction scheme and cost of the optimal multi-energy carbon reduction device.Finally,a comprehensive energy system test example was used for verification.The example obtained the optimal configuration and cost of multi-energy carbon reduction devices under different carbon reduction effects according to the change of weighted average carbon potential,and the carbon reduction amount of each device and the total carbon reduction amount in the whole region,verifying the rationality of the proposed carbon reduction method.The verification results show that the concept of the system weighted average carbon potential proposed in this paper can be used as a carbon reduction sensitivity index to guide each energy subsystem to participate in the carbon reduction optimization process fairly and reasonably.
