摘要
随着风电和光伏等波动性能源并网发电量增加,电力系统的调频任务更加繁重。针对目前国内传统调频资源存在响应时间长、机组爬坡速率低等多种问题,结合储能电源技术响应速度快、控制精度高和双向调节效果好等优点,本文提出一种使用锂离子电容器储能参与火电机组自动发电控制调频的解决方案。根据QC/T 741-2014标准,对锂离子电容器单体(HAA 4V10000F)进行能量密度和功率密度测试,并分析其循环稳定性及循环寿命。通过上述研究验证了该锂离子电容器单体完全适用于火电机组自动发电控制调频领域。
With the increase of fluctuating grid connected power generation such as wind power and photovoltaic,the task of power system frequency regulation becomes more arduous.In view of the problems of long response time and low climbing rate in traditional domestic frequency regulation resources,this paper proposes a solution using lithium-ion capacitor energy storage to participate in automatic generation control frequency regulation of thermal power units.According to QC/T 74-2014 standard,the energy density and power density of lithium-ion capacitor monomer(HAA4V10000F)are tested,and its cycle stability and cycle life are analyzed.Through the above research,it is verified that the lithium-ion capacitor unit is completely suitable for the frequency regulation field of automatic generation control of thermal power units.
