摘　　要：针对不同储能类型运行成本和效率差异性的问题,以蓄电池和超级电容为例,提出一种综合储能协同控制方法用于电网频率控制,期望在提升调频效果的同时满足经济性要求。首先,根据超级电容和蓄电池自身特性,分别采用自适应控制和变系数下垂控制方式进行输出有功调整;然后,基于全寿命周期成本计算两种储能的调频效益,并据此来优化其容量配置;在此基础上,设计调频所需功率分配机制,根据超级电容和蓄电池的剩余调频能力,进行调频任务分配。最后,通过Matlab/Simulink进行仿真验证,结果表明所提方法在电网调频中的经济性和有效性。In view of the variability of operating cost and efficiency of different energy storage types,an integrated energy storage cooperative control method is proposed to meet the economic requirements while improving the grid frequency control effect,which is analyzed in the paper with battery and super-capacitor as examples.Firstly,according to the characteristics of the super-capacitor and battery,the output active power is adjusted by adaptive control and variable coefficient droop control respectively.Then,the frequency modulation benefit of two kinds of energy storage is calculated based on the life-cycle cost.According to that,the capacity allocation is optimized.Based on that,the power distribution mechanism for frequency regulation is designed.The task of frequency regulation is allocated according to the remaining frequency regulation capability of the super-capacitor and the battery.Finally,the simulation results of Matlab/Simulink show that the proposed method is economical and effective in power grid frequency regulation.
