摘　　要：在国内双碳目标以及国际碳关税、新电池法等绿色贸易壁垒影响下,用户侧碳减排需求急剧提升。微电网作为新型电力系统与用电负荷连接的重要桥梁,既能有效平衡本地分布式能源出力,同时可以推动用户侧绿色低碳转型,满足用户碳减排需求。为此,开展考虑碳减排需求的微电网经济运行策略研究。首先,构建了含风电光伏、绿电交易、储能、电动汽车、柔性负荷在内的微电网运行模型;然后,综合考虑碳排放成本、绿色电力交易和系统运行成本建立优化模型;最后,基于CPLEX求解工具对算例展开分析,结果表明所提方法能够适应新能源出力波动、电价变化以及碳价变化,显著降低系统碳排放量,满足微网内用户碳减排需求,提升系统低碳经济运行水平。Under the influence of domestic dual carbon targets,international green trade barriers,the demand for carbon reduction on the user side has sharply increased.As an important bridge connecting new power systems and electricity loads,microgrids can effectively balance local distributed energy output and promote green and low-carbon transformation on the user side,meeting their carbon reduction needs.The economic operation strategy of microgrids considering the demand for carbon reduction is mainly studied.Firstly,a microgrid operation model that includes wind and solar power,energy storage,electric vehicles,and flexible loads is constructed.Then carbon emission costs and system operation costs are comprehensively considered to construct an optimization model.Finally,based on the CPLEX solving tool,the results show that the proposed method can adapt to fluctuations in new energy output,changes in electricity prices,and changes in carbon prices,meet the carbon reduction needs of users within the microgrid,and significantly improve the low-carbon economic operation level of the system.
