摘　　要：由于光伏发电的波动性以及随机性,大量的光伏剩余电量因不满足电网质量要求而被浪费。为了提高光伏发电的利用效率,提出了一种光伏制氢与氢燃料电池联合发电的氢储能-氢利用系统,针对该联用系统进行了建模以及控制策略的研究。通过MATLAB/Simulink软件进行的仿真验证表明,氢储能的介入使得系统可以提供更平滑稳定的电能,同时消纳剩余电量。Due to the volatility and randomness of photovoltaic power generation,a large amount of photovoltaic surplus electricity is wasted because it does not meet the power grid quality requirements.In order to improve the utilization efficiency of photovoltaic power generation,a hydrogen storage-hydrogen utilization system which integrates photovoltaic hydrogen production with hydrogen fuel cell and produces power is proposed,and modeling and control strategies are studied for the integrated system.The simulation test conducted via MATLAB/Simulink software show that the introduction of hydrogen energy storage enables the system to provide smoother and stable power supply while absorbing surplus electricity.
