摘　　要：为促进多微网新能源消纳和低碳经济运行,构建了一种不确定环境下基于纳什谈判的含掺氢燃气综合能源多微网两阶段优化调度方法。首先,对多微网进行低碳改进,提出电解槽和甲烷反应器的量纲统一模型;将燃气掺氢供给燃气机组,建立了含掺氢燃气的氢储能(hydrogenenergy storage,HES)模型;其次,为有效衡量多微网的不确定性,通过多微网与配电网的净交互成本计算条件风险价值(conditional value-at-risk,CVa R),基于纳什谈判理论建立多微网两阶段优化调度模型,第一阶段最小化多微网总运行成本,第二阶段分配收益并最大化各微网利益;最后,构建基于动态自适应惩罚因子的改进交替方向乘子法(alternating direction multiplier method,ADMM)实现调度模型的分布式求解。通过不同场景的算例结果验证了所提模型实现了多微网运行成本的最低化及各微网利益的最大化,此外也保证了新能源消纳,促进了碳减排。同时比较了不同掺氢比以及CVaR风险系数对多微网能效的影响,从而为不确定环境下综合能源多微网的低碳经济调度提供参考。To promote the renewable energy consumption and the low-carbon economic operation of a multi-microgrid,a two-stage optimization scheduling method for the integrated energy multi-microgrid with the hydrogen-doped gas based on the Nash negotiation is constructed under the uncertain environment.Firstly,the low-carbon improvement of the multi-microgrid is carried out,and a unified dimensional model of the electrolyzer and the methane reactor is proposed;by supplying the gas doped with hydrogen to the gas unit,a hydrogen energy storage(HES)model with the hydrogen doped gas is establish.Secondly,to effectively measure the uncertainty of a multi-microgrid,the conditional value-at-risk(CVaR)is calculated by the net interaction cost between the multi-microgrid and the distribution network.A two-stage optimal scheduling model for the multi-micro-networks based on the Nash negotiation theory is developed to minimize the total operating cost of the multi-micro-networks in the first stage and to distribute the benefits and maximize the benefits of each micro-network in the second stage.Finally,an improved alternating direction multiplier method(ADMM)based on the dynamic adaptive punishment is constructed to realize the distributed solution of the scheduling model.The numerical results of different scenarios demonstrate the superiority of the proposed model in reducing the total operating cost of the multiple microgrids,maximizing the benefits of each microgrid,enhancing the new energy consumption and reducing the carbon emissions.The results of different scenarios verify that the proposed model achieves the minimization of the multi-microgrid operation cost and the maximization of the benefits of each microgrid,in addition to ensuring the new energy consumption and promoting the carbon emission reduction.The effects of different hydrogen doping ratios and the CVaR risk factors on the energy efficiency of the multi-microgrid are also compared to provide a reference for the low carbon economic dispatch of the integrated energy
