摘　　要：针对高比例新能源电力系统运行方式复杂多变特征,提出一种基于精细化运行模拟的短期扩展规划方法,实现源-网-储协同优化配置,通过运行过程精细化模拟支撑运行关联指标准确计算,保证规划方案性能指标与规划目标的一致性。构建综合初始投资与运行性能的电力系统源-网-储协同扩展模型;基于模型特征分析将扩展规划问题分解为规划-运行双层优化问题,在运行层面嵌入精细化运行模拟,保证运行指标准确计算;结合双层规划问题特征,融合第二代非支配排序遗传算法(nondominated sorting genetic algorithmⅡ, NSGA-Ⅱ)架构设计求解算法,实现兼顾初始投资与运行性能的方案优选。基于IEEE-30节点系统的算例分析表明,所提扩展规划方法可避免基于典型场景规划方法偏离规划目标的问题,将系统投资与运行总费用降低约2%。Aiming at the complication and variability of the operation mode in power systems with high proportion of renewable energy,a short-term expansion planning method based on refined operation simulation was proposed to realize the synergistic optimal configuration of source-grid-storage.The method supported the accurate calculation of operation indexes through the refined simulation of operation process,so as to ensure the consistency of the operation indexes of planning solutions with objective functions.A synergistic source-grid-storage expansion model of power system that integrated initial investment and operational performance was constructed.The expansion planning problem was decomposed into a two-layer planning-operation optimization problem depending on model characterization,and refined operation simulation was embedded at the operation layer to ensure accurate calculation of operation indexes.The solution algorithm was designed by integrating the nondominated sorting genetic algorithmⅡ(NSGA-Ⅱ)considering the characteristics of the two-layer planning model to realize optimal selection of solutions that considered both the initial investment and the operational performance.Case study based on the IEEE-30 system showed that the proposed expansion planning method could avoid the deviation problem of planning method based on typical scenarios from the planning objectives and reduce the total cost of investment and operation by about 2%.
