摘　　要：在考虑风光不确定性条件下建立一个低碳背景下含电转气的多微网架构分层管理的能量调度模型。上层构建一个混合能源运营商模型,利用改进的蛇算法寻求运营商与微电网群的最优内部电价,在进行功率交换和主网应用分时电价条件下,实现电氢互转,分别协调与主网和微网群调度;下层利用求解器构建微网群间实现相互协作调度模型,将梯度碳交易机制引入各微电网调度阶段。通过仿真验证,该模型最终通过分时电价以及运营商储能储氢实现对主网削峰填谷的作用,同时在阶梯式碳交易模式下,降低碳排,考虑到环境成本,实现微网群与协同运营商的合作联盟。In this paper,an energy dispatching model for hierarchical management of multi-microgrid architecture with electricity-togas in low-carbon background is established under the condition of considering the uncertainty of wind and solar.In the upper layer,a hybrid energy operator model is constructed,and the improved snake algorithm is used to seek the optimal internal electricity price between the operator and the microgrid group,and the power and hydrogen transfer is realized under the condition of power exchange and time-of-use electricity price applied to the main network,and the dispatch of the main network and the microgrid group is coordinated respectively.The lower layer uses the solver to construct a mutual cooperative scheduling model between microgrid groups,and introduces the gradient carbon trading mechanism into the dispatching stage of each microgrid.Through simulation verification,the model finally realizes the role of peak shaving and valley filling of the main grid through time-of-use electricity price and energy storage and hydrogen storage by operators,and at the same time,reduces carbon emissions in the stepped carbon trading mode,considers the environmental cost,and realizes the cooperation alliance between the microgrid group and the cooperative operator.
