不同典型用户侧储能配置评估与运行优化模型

Configuration Evaluation and Operation Optimization Model of Energy Storage in Different Typical User-side

不同典型用户的负荷行为存在很大差异,为使用户侧储能配置更加合理,缓解高峰负荷供需平衡,提出了基于层次分析法的用户侧电池储能系统配置评估与运行优化两阶段模型。首先,以用户侧储能全寿命周期内净收益最大为目标函数,对储能配置进行优化,得到储能配置结果和评估参数;其次基于层次分析法,以储能全寿命周期内净收益、回收年限和投资回报率为评估指标构建判断矩阵,评估不同典型用户储能配置方案的优劣;对适合配置储能的用户,以日调度期内购电成本最低为目标函数,建立日前优化调度模型,优化储能充/放电策略。最后通过Matlab平台分别对4类典型用户进行算例仿真,结果表明目前典型商业用户配置储能效益最佳,并分析了影响储能经济效益的指标,为不同用户侧储能商业化推广提供借鉴。

The load behavior of different typical users is very different.In order to ensure the user-side energy storage configuration more reasonable and ease the supply and demand balance during the peak load,a two-stage model of user-side battery energy storage system(BESS)configuration evaluation and operation optimization is proposed based on the analytic hierarchy process(AHP).Firstly,the BESS configuration is optimized to obtain the configuration results and evaluation parameters by taking the maximum net income of the user’s BESS over its whole life cycle as the objective function.Secondly,the net return,recovery life and return on investment in the whole life cycle of BESS are taken as the evaluation indicators to construct the judgment matrix based on AHP,to assess the merits of different typical user’s BESS configuration schemes.For the users who are adaptable,a day-ahead optimization model is established to optimize the charging/discharging strategy of BESS by taking the lowest power purchase cost in the daily scheduling period as the objective function.Finally,four typical users are chosen as simulation cases on MATLAB platform.The results show that the energy storage benefit of typical commercial users is the best at present,and the indexes affecting the economic benefits of energy storage are analyzed to provide reference for the commercialization and promotion of energy storage by different users.
