摘要
针对太阳能发电输出功率的不连续性和波动性,分析了各种储能电池的优缺点,提出了采用以钒液流电池(VRB)储能来解决这一缺陷的方法,研究了VRB的工作原理及其等效电路模型。在此基础上搭建了其仿真模型,通过采用恒流控制策略在Matlab/Simuink中对VRB特性进行了验证,仿真结果表明VRB能够快速平抑输出功率的波动,可以保证直流电压的稳定,增强系统运行的安全性和供电的可靠性,仿真结果与理论分析相吻合,为进一步研究钒液流电池在大规模光伏发电系统的应用提供了理论指导。
According to the discontinuity and solar power output volatility, this paper analyzes the advantages and disadvantages of various energy storage battery, and proposes an method based on vanadium flow battery （VRB） to solve this problem. We also study the working principle and its equivalent circuit model of VRB, and set up a simulation model in Matlab/Simuink to verify the control strategy characteristics of VRB. Simulation results show that VRB can bring down the output power fluctuation quickly. Conse quent reliab y, VRB can guarantee the stability of the dc voltage, and enhance the system operation safety and lity of power supply.
