摘要 传统混合储能多采用直流母线响应高频负载,超级电容响应中频负载,蓄电池响应低频负载的分频控制,并未考虑负载变化率问题,本文首次提出考虑负载变化率的混合储能优化分频控制。首先根据储能元件Ragone曲线,选择能够覆盖负载频率变化范围最大的超级电容和铅酸电池作为混合储能元件。然后进行混合储能优化分频控制策略的设计,该控制策略采用基于分段函数的功率一次分配和基于分频控制的功率二次分配,且能够提高混合储能响应负载的精度。最后通过仿真实验将所搭建模型应用于居民区微电网负荷削峰,结果与理论分析一致,验证了该控制策略的正确性。 In traditional hybrid storage system,DC bus is used to regulate the high frequency load,super capacitor is used to regulate the medium frequency load,and the battery is used to regulate the low frequency load,but the change rate of the load is not considered in these processes.So in this paper,an optimal frequency division control method of hybrid energy storage is proposed for the first time by considering the change rate of the load.Firstly,the super capacitor and lead-acid battery which can cover the maximum variation of load frequency are selected as the hybrid energy storage components according to the Ragone curves of energy storage elements.And then the control strategy of optimal frequency division of hybrid energy storage is designed,in which the piecewise function based first power allocation and the frequency division control based second power allocation are applied to improve the accuracy of hybrid energy storage system for responding to load.Finally,the model is applied in residential area microgrid to avoid the peak load through simulation.The simulation results conform with the theoretical analysis,which verifies the correctness of the control strategy.
