摘　　要：共享储能是可再生能源实现经济消纳的解决方案之一,在适度的投资规模下,应尽力实现储能电站容量功率与消纳目标相匹配。对此,提出了考虑新能源消纳的共享储能电站容量功率配置方法,针对储能电站投运成本最低与微能源网运行经济性最优的多目标,建立了双层规划模型,其中外层模型求解电站配置问题,内层模型求解经济消纳率及微能源网优化运行问题,使用Karush-Kuhn-Tucker(KKT)法对模型转化求解。算例分析显示:配置共享储能后,微能源网系统运行成本下降15.01%,新能源消纳率提升至97.06%,共享储能服务商可在4.51年收回投资成本。研究结果证明所提构建双层规划配置的方法能较好地考虑新能源经济消纳,提高共享储能电站与微能源网运行的经济性。Shared energy storage is one of the solutions for renewable energy to achieve economic consumption.With a moderate investment scale,efforts should be made to match the capacity and power of energy storage power stations with the consumption target.In this regard,a capacity and power allocation method for shared energy storage power stations considering new energy consumption is proposed,and a bi-level programming model is established for the multi-objectives of the lowest operation cost of energy storage power stations and the optimal operation economy of micro-energy network.For the power station configuration problem,the inner model is used to solve the economic consumption rate and the optimal operation of the micro-energy network,and the KKT method is used to solve the model transformation.The calculation example analysis shows that the operating cost of the micro-energy grid system decreases by 15.01%after the shared energy storage is configured,and the new energy consumption rate increases to 97.06%.The shared energy storage service provider can recover the investment cost in 4.51 years.The research results prove that the two-tier planning and configuration method constructed in this paper can better consider the economic consumption of new energy,and improve the operation economy of shared energy storage power stations and micro-energy grids.
