    摘 要:超级电容- 蓄电池混合储能系统同时具有能量密度高和功率密度高的特点,适用于平抑含有大量分布式能源接入的低压直流配电网的电压波动。提出了一种基于混合储能的母线电压分区控制策略,对母线电压实施5 层电压控制,蓄电池用于稳定波动较小时的母线电压,超级电容平抑母线电压波动较大时的功率差额,给出了一种根据母线电压波动的极端情况配置超级电容容量的方案。经Matlab/Simulink 仿真,验证了该控制策略的可行性。

    Abstract: The super capacitor and battery hybrid energy storage system has the characteristics of high energy density and high power density, which is suitable to stabilize the voltage fluctuation of low-voltage direct current (LVDC) distribution network containing a large number of distributed energy. This paper presented a new bus voltage division control strategy based on hybrid energy storage to implement 5-level voltage control for bus voltage, using the battery to stabilize the smaller bus voltage and using super capacitor to stabilize power balance of the bigger voltage fluctuation, and presenting a scheme to configure the super capacitor capacity based on the extreme conditions of the bus voltage fluctuation. Finally, feasibility of the strategy is verified through the simulation based on Simulink in Matlab.
    Key words: low voltage direct current distribution network; hybrid energy storage; bus voltage; super capacitor
