基于氢储能的光伏发电系统

PV generation system based on hydrogen storage

光伏发电不连续、随机性强,容易对发电系统稳定运行产生不利影响。在光伏发电系统中应用氢储能技术,将光伏电站电能以氢气形式存储起来,在必要时通过燃料电池发电系统释放能量,提高光伏发电的整体利用效率。通过建立各系统的仿真模型,分析总结了各个环节的输出特性。实际案例数据表明氢储能的加入能够提高光伏系统的能量利用效率。

The characteristics of strong discontinuity and randomness in the PV generation are easy to affect the stable of the power system.By applied a hydrogen storage system in the PV generation,the energy of the PV generation was stored in the hydrogen,and was released through the fuel cells system when necessary,complementing the PV generation and improving the overall utilization of effectiveness.Through the establishment of simulation models of system,the output characteristics were analyzed and summarized.The results of actual data show that the hydrogen storage system can improve the energy utilization efficiency of photovoltaic system.
