摘　　要：混合储能目前是一种较为高效的能量存储方式,对于新能源消纳作用极大,大规模投建储能装置有助于提高可再生能源并网的比例,助力“双碳”目标的实现。然而,储能投建成本较高,盲目配置储能将导致大量资金的浪费,如何根据可再生能源的消纳需求来正确配置储能成为了急需解决的问题,需要综合考虑可再生能源的消纳效果以及储能配置的经济性,真正做到“好钢用在刀刃上”。本文提出一种两阶段的储能优化配置方法:第一阶段,对电力系统进行运行模拟,确定最优储能选型方案;第二阶段,充分考虑源测、网架和负荷的灵活调节能力,建立储能的优化配置模型,以最小化投资成本和弃风弃光率为目标,全面考虑发电侧、输电侧和负荷侧的灵活性资源,得到切实可行的储能选址定容方案。通过对算例仿真结果分析得知,本文方法可促进可再生能源消纳,大大缩减投资成本。Energy storage plays an extremely important role in the field of renewable energy consumption.Large⁃scale construction of energy storage will help promotion of the integration of renewable energy into the power system and help to achieve the"dual carbon"goal.However,the investment and construction cost of energy storage is rel⁃atively high,and careless allocation of energy storage will lead to a large waste of funds.Therefore,it is necessary to study the optimal allocation method of energy storage for renewable energy consumption,taking into account of both the consumption effect of renewable energy and the investment funds.This paper proposes a two⁃stage energy storage optimization method.In the first stage,the operation simulation of the power system is performed to deter⁃mine the optimal energy storage type selection scheme.In the second stage,a dual⁃objective optimization model to minimize the investment cost and the curtailment of wind and solar power is constructed,and the model is solved to obtain a realistic energy storage schedule scheme.The case study analysis shows that the proposed method in this paper can greatly increase the consumption of renewable energy and reduce the investment cost.
