摘　　要：混合储能系统的容量配置优化是推进北方乡村风电清洁供暖的重要基础。面向北方乡村住宅,提出了一种风电热泵混合储能系统的容量配置双层优化方法。架构了风电热泵混合储能系统,通过聚类分析方法对乡村住宅的负荷特性进行分析;建立了容量配置双层优化模型,上层以全生命周期净收益最大为目标优化系统的设备容量,下层以运行成本最小为目标优化系统各设备的逐时功率,通过双层模型间的嵌套迭代,得出最优的系统容量配置方案;以辽宁某乡村住宅群为算例进行验证。结果表明:优化后的风电热泵混合储能系统的净收益比仅储电方案高22.08%,比仅储热方案高14.10%,清洁能源利用率达到了99.27%,兼顾了经济效益与风电消纳。在进行容量配置的同时实现了经济运行,可为北方乡村住宅风电混合储能供暖项目提供理论指导。Capacity allocation optimization of hybrid energy storage systems is an important foundation for promoting clean heating from wind power in northern countryside.A two-layer optimization method of capacity allocation for wind power heat pump hybrid energy storage system is proposed for northern rural houses.The wind power heat pump hybrid energy storage system is structured,and the load characteristics of rural houses are analyzed by cluster analysis;A two-layer capacity allocation optimization model is established.The upper layer is to optimize the equipment capacity of the system for the maximum net profit over the entire lifecycle,while the lower layer is to optimize the hourly power of each device in the system for the minimum operating cost.Through nested iterations between the two levels of the model,the optimal system capacity configuration solution was obtained.Finally,a rural residential complex in Liaoning is used as an example for validation.The results show that the optimized wind power heat pump hybrid energy storage system has a net benefit of 22.08%higher than that of the power-only storage scheme and 14.10%higher than that of the heat-only storage scheme,and the utilization rate of clean energy reaches 99.27%,which takes into account the economic benefits and wind power consumption.This study achieves economic operation while performing capacity allocation,providing theoretical guidance for residential wind-power hybrid energy storage heating projects in the northern countryside.
