摘　　要：为充分发挥多能源微网经济、环保等优势,早日实现“碳中和、碳达峰”目标,提出一种基于改进碳交易机制的多能源微网低碳经济调度模型。首先,建立微网内设备全寿命周期内各环节产生的碳足迹计算模型,以评估微网设备碳排放对环境潜在影响。其次,根据设备碳足迹对微网碳交易机制进行修正,并构建碳交易成本;在此基础上,以微网运行总成本为优化目标,建立基于改进碳交易机制的多能源微网低碳经济调度模型,以最小化微网自身碳足迹。最后,应用基于随机模拟的粒子群优化(particle swarm optimization,PSO)算法对该模型进行寻优求解。仿真结果表明,采用所述方法后微网运行成本和CO_(2)排放量分别降低1.08%和6.83%,从而实现微网经济及低碳高效运行。To fully leverage the economic and environmental benefits of multi-energy micro-grids and accelerate the achievement of"carbon neutrality and peak carbon dioxide emissions,"this paper proposes a low-carbon economic dispatching model for multi-energy micro-grids.This model is based on an improved carbon trading mechanism.Initially,a model is formulated to calculate the carbon footprint produced at each link in the entire life cycle of the microgrid equipment,aiming to evaluate its potential environmental impact.Subsequently,the carbon trading mechanism of the microgrid is revised according to this carbon footprint evaluation,and the associated carbon trading costs are calculated.Based on these modifications,a low-carbon economic dispatching model for multi-energy micro-grids is developed.This model sets the minimization of the total operating cost of the microgrid-and hence,its carbon footprint-as the primary optimization objective.In the final stage,a PSO algorithm,supported by stochastic simulation,is applied to optimize this dispatching model.Simulation outcomes indicate that implementing the proposed method leads to a reduction of 1.08%in operating costs and 6.83%in CO_(2)emissions.These results validate the effectiveness of the approach in realizing economical,lowcarbon,and efficient operation of the microgrid.
