摘要

电池储能系统凭借功率输出精确、响应速度快、双向调节等优势

广泛应用于电力系统的调频调峰

但其使用寿命仍是储能系统的核心问题。采用基于电池荷电状态(SOC)反馈的自适应综合调频策略

由模糊控制器调节输入系数和储能电池荷电状态调节反馈系数共同确定自适应因子

输入系数由虚拟惯性控制和虚拟下垂控制的调频出力占比系数

决定。通过Matlab/Simulink平台搭建仿真模型并采用某电厂调频电池的实际运行数据进行了不同控制策略的研究

并利用雨流计数法预测储能电池的使用寿命。结果表明:自适应综合调频策略比目前电厂所用策略下电池的寿命提高25.53%

较定

法和变

法的使用寿命分别提高了38.19%和22.42%。

Abstract

Battery energy storage systems are widely used in frequency and peak regulation of power systems due to their advantages of accurate power output

fast response speed

and two-way regulation

but their service life is still the core restriction of energy storage systems. The adaptive comprehensive frequency modulation strategy based on battery state-of-charge (SOC) feedback was adopted. The adaptive factor was determined by the input coefficient of the fuzzy controller adjustment and the feedback coefficient of energy storage battery SOC adjustment

and the input coefficient was determined by the frequency modulation output proportion co

efficient (

) of virtual inertial control and virtual droop control. The simulation model was developed with the Matlab/Simulink platform

and the actual operation data of the frequency modulation battery of a power plant was used to study different control strategies. The rain-flow counting method was used to predict the service life of energy storage batteries. Results show that the battery life with the adaptive integrated frequency modulation strategy is 25.53% higher than that with the current strategy used in power plants

and the service life is increased by 38.19% and 22.42% compared with the fixed

method and variable

method

respectively.
