太阳能光伏—燃料电池联合发电系统的模拟研究

Simulation Analysis of Photovoltaic-Fuel Cell Hybrid Power Generation Systems

叙述了为保证光伏发电系统长期、连续、稳定的电力供应构建的光伏—燃料电池联合发电系统及通过建立数学模型,利用Matlab模拟软件,进行不同配比电量输出和成本的仿真模拟结果,指出,通过调整系统的配比,可使蓄电池和H2罐的电量输出和成本达到最佳,提出,利用高效蓄电池只能满足短期的负载需求,用长寿命、低价格的H2罐,长时间存储电解的H2,在冬季光照不足时可用燃料电池满足负载需求。联合系统使二者互补,为用户提供长期、高效、连续、稳定的电力供给。

To ensure long-term,continuous and stable power supply of a stand-alone photovoltaic energy system,a photovoltaic-fuel cell（PV-FC） hybrid power generation system is proposed.Based on the mathematical model,this paper mainly did the simulation of power output and cost in different combinations which in the environment of Matlab.By adjusting the ratio of the different systems,ensure the batteries and hydrogen tanks power output and cost achieve the best.The batteries with high efficiency are used to satisfy the short-term demand,and a long life and cheap hydrogen tanks are adopted to store a large amount of energy for a long time.And use fuel cell to meet the load demand in winter.Combined system makes both complementary to provide users with longterm,highly effective,the continuous,stable power supply.
