考虑数据中心和分布式能源接入的配电网双层规划方法 [PDF]
在大数据时代背景下,社会对数据处理需求的增加导致电网中数据中心的负荷不断增长,若按数据中心原始负荷接入电网,会对配电网运行产生较大的负担。而数据中心的批处理负载与配备的储能设备决定了其可以作为灵活性负荷接入电网参与需求响应。通过选取包含数据中心、常规负荷与光伏机组的配电网作为研究对象,采用双层规划方法建立了考虑数据中心运行灵活性和分布式光伏接入的配电网规划模型,上层模型以最小化配电网系统的规划与运行成本为目标,对配电网线路以及其内部的光伏机组与燃气轮机容量进行规划 ...

ABSTRACT Lithium metal batteries (LMBs) promise ultrahigh energy density, yet their advancement is impeded by dendritic lithium growth and unstable interfacial behavior. Herein, for the first time, we present novel lithiophilic CoNiB quantum dots embedded in nitrogen‐doped hollow carbon nanorods (CoNiB@NC) as a multifunctional interlayer on a ...

文中以瓷柱式四断口滤波器断路器电压分布特性展开研究,建立了四断口断路器动态模型和暂态恢复电压仿真电路模型。基于Ansys仿真软件,计算了断口等效电容参数和杂散电容,通过四断口断路器等值电路分析了不同均压措施(电容、电阻、阻容串联、阻容并联)下各断口分压情况。根据静态分压计算结果选择合适的均压电容值和均压电阻值。在动态均压下,由于弧后电阻影响各断口等效参数,通过仿真得出阻容并联对多断口断路器电压分布特性的总体影响规律,提炼出并联阻容优化配置方案。在48 ...
