摘　　要：为应对大规模海上风电的随机性及不确定性,作为灵活性资源的储能受到日益广泛的关注。然而,现有针对新能源并网的储能配置研究聚焦在电源侧,缺乏对电网侧储能的优化配置研究。针对此问题,在考虑海上风电不同出力区间预测误差的基础上,提出一种电网侧储能两阶段选址定容配置方法。第1阶段基于海上风电出力及负荷数据,采用多场景随机规划方法,以经济性最优配置储能容量,最大限度的补偿风电预测误差,减少弃风量和切负荷量;第2阶段建立基于优先选址的多时段最优潮流模型,考虑系统安全性及网络架构,以机组成本最小为目标进行储能选址定容。最后,采用修改后的IEEE39节点系统进行仿真模拟,结合储能综合评价模型,验证本文方法的有效性。To cope with the stochasticity and uncertainty of large-scale offshore wind power,energy storage as a flexible resource receives increasingly widespread attention.However,the existing research on energy storage configuration for grid-connected new energy sources focuses on the power side,and lacks research on the optimal allocation of grid-side energy storage.To address this issue,a two-stage grid-side energy storage configuration method is proposed based on the consideration of the prediction error of offshore wind power in different output intervals.In the first phase,based on offshore wind power output and load data,a multi-scenario stochastic planning method is used to optimally configure the energy storage capacity in an economical way,to maximally compensate for the wind power prediction error and to reduce the amount of wind abandonment and load shedding.In the second stage,a multi-temporal optimal tidal current model based on preferred siting is established,taking system security and network architecture into account,and the minimum unit cost is taken as the objective for energy storage siting and capacity setting.Finally,the modified IEEE39 node system is used for simulation,which is combined with the comprehensive evaluation model of energy storage to verify the effectiveness of the method in this paper.
