摘　　要：为了响应“双碳”目标,应对大规模可再生能源接入带来的弃风光问题,提出一种考虑混合储能的电-氢系统(electrichydrogen system,EHS)日前-日内协同优化调度策略。考虑系统及各出力单元的约束条件,以EHS运行成本最低及碳排放最小建立目标函数;对模型中的非线性约束进行线性化处理,构建混合整数线性规划问题;介绍日前-日内协同的多时间尺度优化调度方法;采用IEEE-33节点系统对所提策略进行算例分析,验证其对促进新能源消纳及EHS低碳经济运行的有效性。仿真结果表明,所提优化调度策略能够有效提高系统可再生能源的消纳能力,减少系统碳排放及运行成本。To respond to the goal of"dual carbon"and deal with the abandonment of wind power and photovoltaic caused by the access of large-scale renewable energy,a coordinated optimal scheduling of an electric-hydrogen system(EHS)considering hybrid energy storage in the day-ahead and intra-day stages was proposed.By considering the constraints of the system and each equipment,the objective function was established to minimize the operating cost and carbon emissions of the EHS.The nonlinear constraints in the model were linearized,and the model of multi-time scale scheduling method was established.The IEEE-33 node system was used to analyze the proposed strategy and verify its effectiveness in promoting the accommodation of renewable energy and the lowcarbon economic operation of the EHS.The simulation results showed that the proposed strategy could effectively improve the system′s accommodation capacity of renewable energy and reduce EHS′s carbon emission and operating costs.
