摘　　要：提出一种计及灵活性和源荷不确定性的储能容量优化配置方法,考虑火电机组和储能对灵活性的影响,并采用模糊机会约束描述源荷不确定性,综合考虑储能投资成本、系统运行成本、灵活性约束和源荷不确定性,建立双层储能配置模型,采用粒子群算法和CPLEX商业求解器进行求解。基于改进的IEEE 30节点系统进行对比验证,结果表明所提模型较传统模型的储能配置结果更合理,系统运行成本更低。Energy storage is an adjustable resource to enhance system flexibility,however,due to its cost constraint,it is difficult to allocate large amounts of energy storage in power systems.To this end,an optimal allocation method of energy storage capacity that considers flexibility and source-load uncertainty is proposed,considering the impact of thermal units and energy storage on flexibility in the system,and using fuzzy chance constraints to describe source-load uncertainty..Based on the improved IEEE 30-node system for comparison and validation,the results show that the proposed model has more reasonable energy storage configuration results and lower system operation cost than the traditional model.
