| 为提升微电网光伏消纳能力,挖掘荷端新型平衡资源灵活潜力,提出一种基于改进同构多胞体的差异化聚合方法。将储能、温控负荷等灵活资源的运行约束统一表征为线性多胞体,经规则化分群后,通过基准同构多胞体的缩放与平移实现内逼近聚合；针对光伏正午大发特性,引入时段差异化权重强化核心时段调节能力,构建以光伏消纳为导向、运行成本最小为目标的微电网日前优化模型。仿真结果表明,所提方法能精准表征聚合灵活性,显著提升光伏消纳水平,平抑出力波动,调度可行性与计算效率满足工程要求,为微电网规模化荷端资源支撑新能源消纳提供高效解决方案。 |

| In order to improve the photovoltaic capacity of microgrid and tap the flexible potential of load end new balance resources, a differentiated aggregation method based on improved isomorphic polyhedron was proposed. The operation constraints of flexible resources such as energy storage, temperature control load and so on are uniformly represented as linear polytopes. After regular grouping, the inner approximation aggregation is realized through the scaling and translation of the benchmark isomorphic polytopes; According to the characteristics of photovoltaic high noon power generation, the time differential weight is introduced to strengthen the regulation ability of the core time period, and the day ahead optimization model of microgrid with photovoltaic consumption as the guidance and minimum operation cost as the goal is constructed. The simulation results show that the proposed method can accurately characterize the polymerization flexibility, significantly improve the PV consumption level, stabilize the output fluctuation, and the scheduling feasibility and calculation efficiency meet the engineering requirements, providing an efficient solution for the large-scale load side resource support of new energy consumption in the microgrid. |
