风氢互补发电系统构建初探

A preliminary study on the construction of wind and hydrogen power electric generating system

为了解决风力发电输出功率的不平稳性和电压的波动性,以解决并网的瓶颈问题,提出风氢互补发电系统,将风力发电输出"波谷"对应的可控出力作为风电场能保证恒定输出的功率,"波峰"至"波谷"之间对应的不可控的出力,采用"波峰"制氢进行"削峰"、"波谷"氢气发电进行"填谷"的方式进行平衡。并以如东风电场为例进行了实例分析与计算,结果证明采用该风氢互补系统基本能保证发电输出平衡,是解决风电并网有效可行的途径。

To deal with the unstable stability of output power and the volatility of voltage in the wind power generation, a wind and hydrogen power electric generating system was put forward in the paper to break though the gridconnected bottleneck. In the system, the controllable output, which corresponds to ＂valley＂ of the wind power generation output, is used as the guarantee steady output power for the wind power plant, and the uncontrollable output corresponding to the part between ＂peak＂ and ＂valley＂ is adopting the peak load shifting mode to balance. In the mode, the ＂peak＂ is used for hydrogen generation to ＂cut the peak＂ and the ＂valley＂ is used for electric power generation by hydrogen to ＂fill the valley＂. What is more, as an example, the Rudongfeng Power Plant was introduced to complete corresponding analysis and computation, and the result showed that the system can guarantee the balance of power output mostly and it can be a feasible and effective way to solve the grid - connection of wind power generation.
